A woman who waited 29 years for a Lyme disease diagnosis is warning people about the dangers of a tick bites

Pauline Bowie, from Clydebank, was bitten in 1989 and for decades experienced chronic fatigue, heart problems and joint pain. 

She was diagnosed with fibromyalgia and ME, but was still struggling with her symptoms when she heard about Lyme disease.

“I was off work, barely able to get out of bed at times and it was just a throwaway comment from my dad,” the 54-year-old said.

“He had been speaking to a cousin of mine who was getting treated for Lyme disease.”

Pauline googled the virus and finally felt “everything fell into place”.   (See link for article)

_________________

SUMMARY:

  • A ‘throwaway’ comment is quite often how “everything falls into place” for people because  government public health has failed to lead mainstream medicine to truth about this plague. Myths have continued unabated for over 40 years and show no sign of changing.
  • Similarly to this patient, nearly everyone who goes to a regular GP to get standardized testing has a negative test – further propelling the Lyme lies.
  • It wasn’t until this patient, like so many others, uses a more sensitive test – vilified by conflict riddled authorities due to their own patent ownership in testing, that she found out not only did she have Lyme, but numerous other tick-borne infections (TBIs). This is also common in Lymeland.
  • And she, like thousands, if not millions more – don’t receive true help until they see a doctor who specializes in TBIs – who are also vilified and called “quacks” by conflict riddled authorities, and who are hunted down by state medical boards and other professional medical groups and are persecuted for helping patients.
  • The patient admits she’s now in remission but has occasional flare-ups – or relapses, necessitating stints of treatment.  This concept is completely denied, ignored, and vilified by mainstream medicine.
  • She also admits she can do things now she hasn’t been able to do since she was in her 20’s, and that it’s been “life changing.”  DITTO!
  • Scientists as Glasgow University have developed a map where members of the public can upload information about where and when they found ticks, and take samples from hot spots.
  • Evidently people from all over Scotland are stating they’ve never seen ticks like they have this year and the team has found larger numbers in urban areas and gardens, and warns that they are everywhere.
  • The article then gives tick prevention ideas which can also be found here in an article that is more thorough & complete. They also recommend changing into a new set of clothes at the end of your activity which is a good idea.  (Put the others in a tightly secured bag and put in dryer on high for 15-20 min when you get home)
  • They also give a section on what to do if you are bitten.  I believe this article is better.  The article quotes the International Lyme and Associated Diseases Society (ILADS – how to handle a tick bite):

    “ILADS recommends that prophylaxis (preventive treatment) be discussed with all who have had a blacklegged tick bite. An appropriate course of antibiotics has been shown to prevent the onset of infection.

    When the decision is made to use antibiotic prophylaxis, ILADS recommends 20 days of doxycycline (provided there are no contraindications).The decision to treat a blacklegged tick bite with antibiotics often depends on where in the country the bite occurred, whether there was evidence that the tick had begun feeding, and the age of the person who was bitten.  Based on the available evidence, and provided that it is safe to do so, ILADS recommends a 20-day course of doxycycline.

  • Personally, I would treat each and every black-legged tick bite with antibiotics/antimicrobials.  The risk just isn’t worth it. Taking the “wait and see” approach is foolish considering the potential devastating outcome.

Deer Keds, Flying Ticks?

https://www.iamexpat.de/expat-info/german-expat-news/tick-season-germany-look-out-flying-ticks

Tick season in Germany: Look out for “flying ticks”

27 July 2021, by William Nehra

Excerpts:

Ticks can cause similar problems amongst humans, spreading diseases like tick-borne encephalitis (TBE) and Lyme disease, as well as some other, lesser-known diseases like babesiosis and boutonneuse fever. In 2019, a Hyalomma tick even infected a man in North Rhine-Westphalia with typhus.

Beware of “flying ticks”

Between July and October, the deer louse fly is also active in Germany. Sometimes known as a “flying tick”, these critters make a beeline for their target and then shed their wings when they land, burrowing down, biting and sucking blood from their victims. The ticks usually target animals, but attacks on humans have been recorded. They prefer to bite humans on the scalp or neck and can cause allergic reactions and even heart infections.

Deer louse flies are usually found in forests in the summer and autumn. It is recommended to thoroughly check any pets after walks in case they have been bitten by ticks. Ticks can be located using a flea comb and removed with adhesive tape or washed away. Any animal that has been infested with ticks should be bathed and washed.

The deer ked (Lipoptena cervi) mainly parasitize elk and deer but also bite humans.  It is unknown whether it serves as a vector for transmission but the following have been detected:

Remains of L. cervi have been found on Otzi, the Stone Age mummy.

Read the following on the deer fly (200 species in the Chrysops genus):

While male deer flies collect pollen, female deer flies feed on blood, which they require to produce eggs.[4] Females feed primarily on mammals. They are attracted to prey by sight, smell, or the detection of carbon dioxide. Other attractants are body heat, movement, dark colours, and lights in the night. They are active under direct sunshine and hours when the temperature is above 22 °C (71.6°).[4] When feeding, the females use scissor-like mandibles and maxillae to make a cross-shaped incision and then lap up the blood. Their bite can be painful. Anti-coagulants in the saliva of the fly prevents blood from clotting and may cause severe allergic reactions. Parasites and diseases transmitted by the deer fly include tularemia, anthrax, anaplasmosis, equine infectious anemia, hog cholera, and filiariasis. DEET is not an effective repellent.[2]

New records show spread of parasitic deer flies across the United States

Date:
May 31, 2019
Source:
Penn State
Summary:
With flattened bodies, grabbing forelegs and deciduous wings, deer keds do not look like your typical fly. These parasites of deer — which occasionally bite humans — are more widely distributed across the US than previously thought, according to entomologists, who caution that deer keds may transmit disease-causing bacteria.

With flattened bodies, grabbing forelegs and deciduous wings, deer keds do not look like your typical fly. These parasites of deer — which occasionally bite humans — are more widely distributed across the U.S. than previously thought, according to Penn State entomologists, who caution that deer keds may transmit disease-causing bacteria.

“It was more or less known where deer keds are found, but very broadly,” said Michael Skvarla, extension educator and director of the Insect Identification Lab in the Department of Entomology at Penn State. “We don’t know if deer keds transmit pathogens (disease-causing microorganisms), but if they do, then knowing where they are at more precisely could be important in terms of telling people to watch out for them.”

The researchers collated records of the four North American deer ked species and produced the most detailed locality map of these flies to date, documenting ten new state and 122 new county records. The researchers published their results in a recent issue of the Journal of Medical Entomology. They also provided an illustrated species-identification key.

The team harnessed citizen science — collection of data by the public — to gather deer ked records from the U.S. and Canada. In addition to scouring museum databases and community websites like BugGuide and iNaturalist, the team distributed deer ked collection kits to hunters as part of the Pennsylvania Parasite Hunters community project. The researchers also collected flies directly from carcasses at Pennsylvanian deer butcheries.

“I really like using citizen science information,” said Skvarla. “It often fills in a lot of gaps because people are taking photographs in places that entomologists may not be going. Deer keds are the perfect candidate for citizen science. They’re easy to identify because there’s only four species in the country and because they’re mostly geographically separated. And as flat, parasitic flies, they’re really distinctive. You couldn’t do this with a lot of insect groups because they’d be too difficult to identify from photographs.”

The European deer ked, Lipoptena cervi, thought to have been introduced from Europe, previously was reported to occur throughout the Northeast region. The researchers newly report this species from Connecticut, Rhode Island, Vermont, and as far south as Virginia. In Pennsylvania, it occurs throughout the state, with 26 new county records.

The researchers also describe new records of the neotropical deer ked, L. mazamae, from North Carolina, Tennessee and Missouri — increasing its range further north and east than had previously been reported.

In western North America, two deer ked species, L. depressa and Neolipoptena ferrisi, are found from British Columbia through the U.S. and into Mexico — and as far east as South Dakota. The researchers newly report these species from Nevada and Idaho.

Deer keds are usually found on deer, elk and moose, but occasionally bite humans and domestic mammals. Although several tick-borne pathogens — including bacteria that cause Lyme disease, cat scratch fever and anaplasmosis — have been detected in deer keds, it is unknown whether they can be transmitted through bites.

“In Pennsylvania you have a lot of hunters,” said Skvarla.

“Deer keds can run up your arm while you’re field dressing a deer and bite you. If these insects are picking up pathogens from deer, they could transmit them to hunters. With two million hunters in the state, that’s not an insignificant portion of the population. We don’t want to scare people, but people should be aware there is the potential for deer keds to transmit pathogens that can cause disease.”

The researchers will next screen hundreds of deer keds for pathogens. They will also dissect some insects to screen the salivary glands and guts separately. According to Skvarla, this approach will give a good indication of whether deer keds could transmit pathogens through bites, or whether the bacteria are merely passed through the gut after a blood meal.

In Pennsylvania, after deer keds emerge from the soil each fall, they fly to a host and immediately shed their wings, usually remaining on the same host for life. Females produce just one egg at a time — it hatches inside her, and she feeds the growing larva with a milk-like substance. When the larva is almost fully developed, it drops to the soil and forms a pupa, eventually emerging as a winged adult. If disease-causing bacteria are transmitted from mother to offspring, newly emerged flies could pass on pathogens to hosts. Pathogens could also be spread when bacteria-harboring flies jump between animals in close contact.

The other researcher working on this project was Erika Machtinger, assistant professor of entomology at Penn State.

Deer Ked: A Lyme-Carrying Ectoparasite on the Move

Cutis. 2018 August;102(2):121-122
By Andrew Kelsey, MDJustin Finch, MD
Author and Disclosure Information

Lipoptena cervi, known as the deer ked, is an ectoparasite of cervids traditionally found in northern European countries such as Norway, Sweden, and Finland. Although rarely reported in the United States, this vector recently has been shown to carry Borrelia burgdorferi and Anaplasma phagocytophylum from specimens collected domestically. Importantly, it has been suggested that deer keds are one of the many disease-carrying vectors that are now found in more expansive regions of the world due to climate change. We report a rare sighting of L cervi in Connecticut. Additionally, we captured a high-resolution photograph of a deer ked that can be used by dermatologists to help identify this disease-carrying ectoparasite.

Practice Points

  • There are many more disease-carrying arthropods than are routinely studied by scientists and physicians.
  • Even if the insect cannot be identified, it is important to monitor patients who have experienced arthropod assault for signs of clinical diseases.

Case Report

A 31-year-old man presented to the dermatology clinic 1 day after mountain biking in the woods in Hartford County, Connecticut. He stated that he found a tick attached to his shirt after riding (Figure). Careful examination of the patient showed no signs of a bite reaction. The insect was identified via microscopy as the deer ked Lipoptena cervi.

Comment

Lipoptena cervi, known as the deer ked, is an ectoparasite of cervids traditionally found in Norway, Sweden, and Finland.1 The deer ked was first reported in American deer in 2 independent sightings in Pennsylvania and New Hampshire in 1907.2 More recently deer keds have been reported in Massachusetts, New York, Pennsylvania, and New Hampshire.3 In the United States, L cervi is thought to be an invasive species transported from Europe in the 1800s.4,5 The main host is thought to be the white-tailed deer (Odocoileus viginianus). Once a suitable host is found, the deer ked sheds its wings and crawls into the fur. After engorging on a blood meal, it deposits prepupae that fall from the host and mature into winged adults during the late summer into the autumn. Adults may exhibit swarming behavior, and it is during this host-seeking activity that they land on humans.3

Following the bite of a deer ked, there are reports of long-lasting dermatitis in both humans and dogs.1,4,6 One case series involving 19 patients following deer ked bites reported pruritic bite papules.4 The reaction appeared to be treatment resistant and lasted from 2 weeks to 12 months. Histologic examination was typical for arthropod assault. Of 11 papules that were biopsied, most (7/11) showed C3 deposition in dermal vessel walls under direct immunofluorescence. Of 19 patients, 57% had elevated serum IgE levels.4

In addition to the associated dermatologic findings, the deer ked is a vector of various infectious agents. Bartonella schoenbuchensis has been isolated from deer ked in Massachusettes.7 A recent study found a 75% prevalence of Bartonella species in 217 deer keds collected from red deer in Poland.5 The first incidence of Borrelia burgdorferi and Anaplasma phagocytophylum in deer keds was reported in the United States in 2016. Of 48 adult deer keds collected from an unknown number of deer, 19 (40%), 14 (29%), and 3 (6%) were positive for B burgdorferi, A phagocytophylum, and both on polymerase chain reaction, respectively.3

A recent study from Europe showed deer keds are now more frequently found in regions where they had not previously been observed.8 It stands to reason that with climate change, L cervi and other disease-carrying vectors are likely to migrate to and inhabit new regions of the country. Even in the current climate, there are more disease-carrying arthropods than are routinely studied in medicine, and all patients who experience an arthropod assault should be monitored for signs of systemic disease.

How to Protect Yourself From Ticks With Permethrin-Treated Clothing

How to protect yourself from ticks with Permethrin-treated clothing

how-to-protect-yourself-from-ticks

Several studies have found that wearing permethrin-treated clothing can reduce the risk of tick bites. But very few studies have looked at the behavior of a tick when it comes in contact with permethrin-treated clothing. Does it climb onto the insecticide-soaked textile or avoid it entirely? Does permethrin actually kill ticks?

By Dr. Cameron

As more individuals begin to venture outside with warmer weather, there are often concerns over how to protect yourself from ticks. Researchers have examined not only the effectiveness of various repellents and protective clothing but also the behavior of individuals who are more likely to encounter ticks.

Researchers in Indiana looked at the protective measures used by recreational hikers in their state. Surprisingly, they found that only 9.5% of hikers used a tick repellent, even fewer (3.4%) wore protective clothing and only 2 individuals “indicated that they took a shower post-recreation and used that activity to search for tick bites.” [1]

Ultrasonic device

Meanwhile, investigators in Australia recently studied the efficacy of ultrasonic pest repellent devices against the Australian paralysis tick, Ixodes holocyclus. “As more than 80% of the ticks were not repelled within the confined area, this level of repellency is clearly insufficient to provide adequate protection from a potential tick bite,” they conclude. [2]

Permethrin-treated clothing

Several studies have looked at Permethrin-treated clothing in repelling ticks.  Sullivan et al. recruited state and county park employees from North Carolina to wear long-lasting Permethrin-impregnated (LLPI) clothing. The authors found that the clothing “retained Permethrin and bioactivity against ticks after three months of use in real-world conditions.” [3]

A study in Rhode Island aimed to provide insight as to how to protect yourself from ticks by examining Permethrin-treated footwear. The authors found that people wearing sneakers and socks treated with Permethrin were 73.6 times less likely to have a tick bite than those wearing untreated footwear. [4]

Researchers found “people wearing sneakers and socks treated with Permethrin were 73.6 times less likely to have a tick bite than those wearing untreated footwear.”

Meanwhile, another study explored the behavior of ticks when they encounter Permethrin-treated clothing. How do ticks react? Using a model that mimicked a pant leg or the arm of a long-sleeved shirt, scientists studied the behavior and fate of ticks when exposed to Permethrin-treated clothing. [5]

“Ticks approaching a textile impregnated with a strong non-contact spatial repellent (DEET) very rarely made physical contact with the treated textile,” according to Eisen and colleagues from the Division of Vector-Borne Diseases, National Center for Emerging and Zoonotic Infectious Diseases at the Centers for Disease Control and Prevention. [4]

Tick behavior when exposed to Permethrin

However, Permethrin-treated textiles did not repel ticks without contact, as seen with DEET. In fact, the majority (88%) of nymphal ticks chose to move onto Permethrin-treated textile versus DEET-treated textile.

After coming in contact with the treated clothing, the ticks dislodged through a “hot-foot” effect.

“Ticks readily walked onto a Permethrin-treated textile…. but laboratory-reared ticks became visibly agitated, displaying a hot-foot effect, and escaped contact with the Permethrin-treated textile by tumbling downwards until they dislodged themselves completely from a textile-covered assay card.”

Unfortunately, field-collected ticks were hardier than laboratory-reared ticks and able to sustain longer contact with the treated textile. The authors postulated that field-collected ticks have been exposed to highly variable temperatures and humidity conditions which may result in slower absorption of Permethrin.

“However, by 1 and 24 hours post-exposure very few ticks displayed normal movement, thus presenting minimal risk to bite, regardless of whether they were reared in the laboratory or collected in the field.”

“Contact with Permethrin-treated textiles negatively impacts the vigor and behavior of nymphal ticks for >24 hours,” according to Eisen, “with outcomes ranging from complete lack of movement to impaired movement and unwillingness of ticks displaying normal movement to ascend onto a human finger.”

One day after exposure, a majority of ticks were completely motionless. The remaining ticks were able to recover. “Ticks having recovered normal movement 1 day after exposure in our study most often ascended onto a finger when given the opportunity (and presumably also were capable of biting),” Eisen points out.

“In a real-life scenario, prolonged periods of time where ticks having fallen off a human host after contact with Permethrin-treated textile are unable to move will undoubtedly increase the risk of mortality due to desiccation or predation.”

“A scenario more difficult to address in a bioassay is when a tick makes initial contact with bare skin and subsequently approaches loose-fitting summer-weight Permethrin treated garments, such as shorts or a T-shirt,” states Eisen.

“In this case, the tick may walk underneath the treated textile and be contacted primarily from the dorsal side as the person moves and the clothing comes in and out of contact with the tick and the person’s skin.”

Permethrin is acutely toxic in high doses. The authors did not address the potential toxicity of Permethrin to humans. “Acute signs of toxicity to the central nervous system include incoordination, ataxia, hyperactivity, convulsions, and finally prostration, paralysis, and death,” according to a review by the National Research Council (US) Subcommittee to Review Permethrin Toxicity from Military Uniforms. [6]

Note: Users have been advised not to inhale Permethrin when treating clothes and not to apply Permethrin to the skin.

How Prevalent is Bartonella?

https://www.lymedisease.org/bartonella-prevalent-lyme-disease/

How prevalent is Bartonella in people who have Lyme disease?

July 15, 2022

By Lonnie Marcum

At a meeting of the federal Tick-Borne Disease Working Group on March 1, Ben Beard, PhD of the CDC made a highly significant statement that passed without remark at the time.

Beard’s statement was in reply to a comment by Monica Embers, PhD, also a member of the working group. Embers noted that several slides from Beard’s Clinical Presentation and Pathogenesis subcommittee mentioned neuropsychiatric illness and neuropathic manifestations of Lyme disease.

“We’re seeing a lot more neuropsychiatric disease associated with Bartonella,” said Embers. “I’m wanting to hear more about your thought process and your recommendation with respect to bartonellosis?”

Bartonella’s “significant impact”

Beard replied:

“In my view Bartonella is ubiquitous. There are multiple different Bartonella species. A lot of people are exposed to cats and fleas, and Bartonella henselae–or cat scratch disease–is pretty common. Our group looked at it as an illness that is associated with people with other tick-borne illnesses. Not necessarily agreeing that it’s tick-borne—for me the jury is still out for that—but I’m perfectly convinced that it is very common, and that it may be confounding the diagnosis, and that it is an important co-infection. We need not get side-tracked on whether or not it’s tick-borne. We need to agree that it’s a common infection, commonly seen in patients with other illnesses, and it can have a significant impact on clinical outcome and presentation.”

This is actually a showstopper of a comment.
The CDC has long declined to categorize bartonellosis as tick-borne and has not considered it a co-infection of Lyme.

Even today, the CDC website states: “Ticks may carry some species of Bartonella bacteria, but there is currently no causal evidence that ticks can transmit Bartonella infection to people through their bites.”

Yet, as Beard observed, Bartonella is very common in people with Lyme disease.

What the data says

In MyLymeData, LymeDisease.org’s patient-led research project, 60% of patients with chronic symptoms of Lyme disease report co-infections. A previously published LymeDisease.org survey of over 3,000 patients found that over 50% had co-infections, with 30% of patients reporting two or more. Bartonella (28%) was the second most commonly reported co-infection associated with chronic Lyme disease. (Johnson, L., et al., 2014)

Bartonella does not respond to standard treatment for Lyme disease, and it is notoriously difficult to detect through standard tests. Moreover, Bartonella is not included in standard surveillance testing for ticks, and cases of the disease are not tracked by the CDC

Which leads me to the elephant in the room: nobody knows how many cases of bartonellosis there are in the US—or anywhere else for that matter.

What is bartonellosis?

Bartonellosis is caused by one of many species of the bacterium Bartonella. It is harbored in wild and domestic animals, and can be transmitted to humans through a number of different pathways including fleas, flies, lice, animal bites, animal scratches, ticks, bedbugs, and possibly through maternal fetal transmission. (Maggi RG, et al., 2015; Reis C, et al., 2011)

First identified in 1990, Bartonella henselae bacteria is the most common cause of bartonellosis in humans. Bartonella henselae infection, also called cat scratch disease, is frequently caused by flea bites or the scratch of an infected cat. The primary reservoirs for B. henselae across the world are domestic and stray cats, and the primary vector is the cat flea (ctenophalides felis). (Breitschwerdt, E.B., 2017)

Prior to 1990, there were only two diseases known to be caused by Bartonella bacteria. One was “Carrion’s disease,” endemic to parts of South America, caused by Bartonella bacilliformis. The other was “trench fever,” which infected many soldiers during World War I, caused by Bartonella quintana.  Though the illness was first described in 1915, Bartonella quintana was not  molecularly identified as its cause until 1961. (Breitschwerdt, E.B., 2017)

We now know that these bacteria have been infecting humans for thousands of years. Researchers discovered Bartonella quintana in a 4,000-year-old human tooth in France. (Drancourt M., et al., 2005)

Today, at least 40 different species of Bartonella have been identified.  About half of them are known to cause symptoms in humans or animals.

Bartonella is a stealth pathogen

At a recent conference, Dr. Ed Breitschwerdt, DVM, a leading expert in the field,  explained how Bartonella can invade and “literally affect every system in the body.” This includes the: cutaneous, muscular, skeletal, endocrine, cardiovascular and nervous systems.

He reviewed several recent studies implicating Bartonella infection in the brain in relation to several neuropsychiatric and autoimmune manifestations.

According to Breitschwerdt, these bacteria are extremely difficult to find in humans because they are slow growing and can hide within cells.

He explained how Bartonella, which are intracellular bacteria, have the ability to:

  • invade red blood cells, wall themselves off, and hide from the immune system (immune evasion)
  • migrate into the nervous system via macrophages (Trojan horse)
  • penetrate the blood brain barrier via endothelial cells and pericytes
  • persist within the brain via microglial cells.

Considering the number of different species and different methods of contracting Bartonella, Dr. Breitschwerdt ponders, “Is Bartonellosis a modern-day hidden epidemic?” (Breitschwerdt E.B., 2014)

Symptoms of bartonellosis

The symptoms of bartonellosis can range from mild to life-threatening, depending on the Bartonella species and the health of those infected. Furthermore, a growing body of evidence links Bartonella to neuropsychological symptoms.

The most commonly reported neurological symptoms include sleep disorders, mental confusion, memory loss, brain fog, irritability, rage, anxiety, panic attacks, depression, migraines, tremors, hallucinations, psychosis and postural orthostatic tachycardia (POTS).

Additional symptoms common to bartonellosis are swollen lymph nodes (especially around the head, neck and arm pits), bone pain (especially shins), pain in the soles of the feet, low grade fever in the morning, night sweats, tender nodules along the extremities, gastrointestinal pain, and skin markings (striae) that resemble stretch marks.

The table below lists the known species of Bartonella associated with human disease, the most common symptoms as well as the reservoir host and vector.

bartonella symptoms

How a stealth pathogen may prolong your chronic illness

In individuals with strong immune systems, Bartonella infection is often mild or asymptomatic. However, in those with an impaired immune system, Bartonella can wreak havoc on the body.

In fact, Bartonella henselae was discovered in the 1990s during the AIDS epidemic. Because  the HIV virus causes an acquired immune deficiency, these patients were extremely susceptible to new infections and reactivation of latent infections. In this patient population, Bartonella caused a distinctive skin lesion called bacillary angiomatosis (BA), and a type of liver disease called peliosis hepatis. (Breitschwerdt, E.B., 2017)

Advanced, disseminated disease is more likely to occur in immunocompromised patients or those taking immunosuppressive drugs. Without proper treatment, the infection can spread systemically throughout the body. The result is sometimes fatal.

When the co-infection becomes the main infection

Data from multiple animal studies shows that Borrelia burgdorferi suppresses the immune system. (Buffen K, et al., 2016; Tracy KE, Baumgarth N., 2017)

This makes me wonder. How many people with chronic Lyme disease had a latent Bartonella infection that was re-activated when their immune system became impaired?

I believe this was the case with my daughter. We live on a farm with lots of animals, including cats. Veterinarians, cat owners, and people who live or work on farms are at increased risk for Bartonella.

It wasn’t until my child became deathly ill after contracting Ehrlichia chaffeensis that her Bartonella symptoms began.

The symptoms that stood out were the constant migraine/headache, memory loss, bone pain, painful soles of feet, relapsing fever, insomnia, nighttime hallucinations that made everything look like Whoville, POTS, skin marks (striae) that resembled stretch marks, swollen lymph nodes, and an immune system so impaired it led to a temporary misdiagnosis of HIV. What a horrific experience for all of us!

Diagnosis & Treatment

Because  Bartonella may hide inside of cells and only emerge periodically, you may need to test multiple times to find a confirmatory diagnosis. And in patients who are immunocompromised, the test may not turn positive until after treatment has begun.

Research led by Ricardo Maggi, Ed Breitschwerdt and colleagues has led to the development of a new digital PCR that is much more sensitive to Bartonella. Even still, Dr. Maggi recommends running multiple types of tests (IFA serology, PCR, culture, and microscopy).

According to Dr. Joseph Burrascano, one should consider bartonellosis when symptoms persist after treatment for Lyme disease. Especially when the neurological symptoms are out of proportion to the common symptoms of disseminated Lyme disease.

Just as with Lyme disease, the longer Bartonella goes untreated, the more difficult it is to treat.  Furthermore, the standard treatment for Lyme (doxycycline) is ineffective against Bart. As Dr. Breitschwerdt famously said, “You cannot float humans or horses in enough doxycycline to kill this bacteria.”

According to the CDC: “A number of antibiotics are effective against Bartonella infections, including azithromycin, penicillins, tetracyclines, cephalosporins, aminoglycosides, and macrolides. More than one antibiotic is often used. Consult with an expert in infectious diseases regarding treatment options.”

Dr. Burrascano says, treating Bartonella-like organisms “can be difficult, as drug resistance can rapidly develop to macrolides and fluoroquinolones when used as a single agent and solo courses of tetracyclines are ineffective.”

Moving forward with Bartonella research

In 2021, a new Bartonella Research Consortium was formed with a $4.8 million grant from The Steven & Alexandra Cohen Foundation.

The consortium includes Ed Breitschwerdt and Ricardo Maggi of North Carolina State University, Monica Embers of Tulane University, and Timothy Haystead of Duke University, who is continuing the work of the late Dr. Neal Spector.

The team is actively working towards creating a targeted treatment for bartonellosis and quickly getting the drug to the marketplace for use in both animals and humans.

It’s time medicine moves beyond the one-pathogen-one-disease model. Let’s face it, ticks are full of toxic soup. Because each pathogen interacts with the host in unique ways, extensive research is needed to understand all factors surrounding co-infections and Lyme disease. (Moutailler S, et al., 2016)

Understanding the complex nature of these pathogens, how they impact the immune system, and how other bacterial and viral factors shape illness, will be key in improving public health. (Cheslock, M. A., & Embers, M. E., 2019)

It’s time for the CDC, NIH, HHS, the Tick-Borne Disease Working Group and other researchers to start looking deeper into the prevalence of Bartonella infections–not just in patients with Lyme disease but in all patients with poorly-defined chronic illnesses.

Excellently written.  Bartonella is a real problem out here, but the CDC is just sipping on margaritas.
