In a study published in mBio, a journal of the American Society for Microbiology, Jorge Benach and Rafal Tokarz, and their co-authors at Stony Brook University and Columbia University, reported on the prevalence of multiple agents capable of causing human disease that are present in three species of ticks in Long Island.

Tick-borne diseases have become a worldwide threat to public health. In the United States, cases more than doubled, from 22,000 in 2004 to more than 48,000 in 2016, according to the U.S. Centers for Disease Control. Tick-borne diseases range from subclinical to fatal infections with disproportionate incidence in children or the elderly. Moreover, some infections can also be transmitted by blood transfusions and cause severe disease in patients with underlying disorders. While public attention has focused on Lyme disease, in recent years, scientists have uncovered evidence that ticks can carry several different pathogens capable of several different tick-borne diseases, sometimes in a single tick.

In the new study, researchers collected ticks from multiple locations throughout Suffolk county in the central and eastern part of Long Island, where seven diseases caused by microbes transmitted by ticks are present. In total, they examined 1,633 individual ticks for 12 separate microbes. They found that more than half of the Ixodes (deer ticks) were infected with the Lyme disease agent, followed by infections with the agents of Babesiosis and Anaplasmosis. Importantly, nearly one-quarter of these ticks are infected with more than one agent, resulting in the possibility of simultaneous transmission from a single tick bite.

Notably, the lone star tick, a species originating from the southern U.S., has expanded its range, possibly fueled by climate change. This study documents that the invasive lone star tick is abundant in Long Island, and that it is a very aggressive tick that can transmit a bacterium that causes a disease known as Ehrlichiosis. The lone star tick has also been implicated in cases of a novel form of meat allergy, and the immature stages can cause an uncomfortable dermatitis.

Polymicrobial infections represent an important aspect of tick-borne diseases that can complicate diagnosis and augment disease severity,” says corresponding author Jorge Benach, PhD, Distinguished Professor at the Department of Microbiology and Immunology at the Renaissance School of Medicine at Stony Brook University. “Some of the polymicrobial infections can be treated with the same antibiotics, but others require different therapies, thus enlarging the number of drugs to treat these infections.”

“In evaluating tick-borne infection, more than one organism needs to be considered,” says senior author Rafal Tokarz, PhD, assistant professor of epidemiology in the Center for Infection and Immunity at the Columbia Mailman School of Public Health, and a graduate of the Department of Microbiology and Immunology at Stony Brook University. “This study emphasizes the need to focus on all tick-borne diseases, not just Lyme.”

Avid Hiker Meets Bad Bug, Ends Up With Babesiosis

Avid hiker meets bad bug, ends up with babesiosis

Dear Dr. Roach • I am an avid hiker, and I live in an area with lots of Lyme disease. I recently developed some fever, headache, shaking chills and dark urine, and just felt awful. My doctor did some blood tests and said I had Babesia and/or Anaplasma. Are these related to Lyme disease? — I.J.M.

 

Answer • Like Lyme disease, babesiosis (caused usually by Babesia microti) and anaplasmosis (caused by Anaplasma phagocytophilium) can be spread by the bite of the deer tick, Ixodes scapularis, but neither bacteria species is related to Borrelia burgdorferi, the cause of Lyme disease. These diseases are not well-known by most people, nor even by many general doctors outside the areas where they are common, such as Wisconsin and Connecticut.

Babesiosis causes fever as high as 105.6 F, fatigue and feeling unwell. Dark urine is occasionally present. There are nonspecific lab findings, such as anemia and low platelet counts, but the diagnosis is confirmed by seeing the bacteria inside the red blood cells or by sophisticated blood testing (PCR). Treatment is with azithromycin and atovaquone.

Anaplasmosis has a generally lower fever, muscle aches, headache, chills and the same feeling of being unwell (called “malaise” in medical literature). Blood counts frequently show low white blood cell counts. The diagnosis is made by antibody or PCR testing, but treatment is usually started in the appropriate setting even before positive results. Treatment is with doxycycline.

Tickborne diseases may exist at the same time, so consideration must be given to people having both anaplasmosis and babesiosis, with or without Lyme disease.Doxycycline treatment for anaplasmosis also treats early Lyme disease, but does not treat babesiosis.

Both anaplasmosis and babesiosis can be very severe in people with immune system disease, such as HIV or an organ transplant. Older people are also at higher risk for severe disease.

**Comment**

This article reminds us of issues that demand answers:

  1. Why does mainstream medicine STILL know so little about tick-borne diseases after 40 years? https://madisonarealymesupportgroup.com/2019/08/22/early-diagnosis-necessitates-lyme-savvy-doctors/
  2. Why is testing STILL being used that is so unreliable after 40 years?  https://madisonarealymesupportgroup.com/2019/08/05/controversies-challenges-in-treating-lyme-other-tick-borne-diseases/
  3. Please notice the doctor’s wise usage of “usually caused by?” This is wise because it could be one of a number of strains of Babesia.
  4. Please notice the the doctor’s wise explanation that a tick bite can transmit a whole host of pathogens – not just Lyme and sometimes not Lyme at all.  This issue is what is completely being neglected in mainstream medicine because doctors aren’t looking at all for any of these coinfections that can come with or without Lyme. Since testing is abysmal for ALL of them, they should be educated in symptomology since diagnosis has always been and still is a clinical diagnosis. Testing is not accurate and should not be the sole means of diagnosis.
  5. Little research has been done on concurrent infection & what it does to the body and how it affects testing:  https://madisonarealymesupportgroup.com/2018/10/30/study-shows-lyme-msids-patients-infected-with-many-pathogens-and-explains-why-we-are-so-sick/  But this recent study shows by Garg et al. shows a 85% probability for multiple infections including not only tick-borne pathogens but also opportunistic microbes such as EBV and other viruses.  Mainstream medicine isn’t touching this with a ten foot pole.
  6. The good doctor points out that anaplasmosis and babesiosis can be very severe in people with compromised immune systems. I believe tick borne illness compromises the immune system greatly and it’s only logical to conclude that concurrent infection with numerous pathogens do so even more. Add a few opportunistic infections like Chlamydia and EBV, and you have a patient as sick as a dog:  https://madisonarealymesupportgroup.com/2016/10/07/chlamydia-like-organisms-found-in-ticks/https://madisonarealymesupportgroup.com/2017/04/11/diagnosed-with-ebv-had-lyme/  This is why patients are so sick and why standard mono therapy often doesn’t work.
Taking into account the totality of these issues presents an entirely different picture than what authorities such as the IDSA and CDC present.

This is often a complex illness with many moving parts which necessitates various drugs of longer duration than currently being used.

The CDC/IDSA “One size fits all” approach just doesn’t work. Until authorities take into account these variables and allow doctors to treat patients accordingly, it’s a losing battle – and make no mistake about it – it’s the patients who loose.

Human Seroprevalence of Tick-Borne Anaplasma, Lyme, and Rickettsia Species in Northern California

https://www.ncbi.nlm.nih.gov/pubmed/31295054/

Human Seroprevalence of Tick-Borne Anaplasma phagocytophilum, Borrelia burgdorferi, and Rickettsia Species in Northern California.

Abstract

There is a paucity of data on human exposure to tick-borne pathogens in the western United States. This study reports prevalence of antibodies against three clinically important tick-borne pathogens (Borrelia burgdorferi, Anaplasma phagocytophilum, and Rickettsia spp.) among 249 people in five counties in northern California. Individuals from Humboldt County were recruited and answered a questionnaire to assess risk of exposure to tick-borne pathogens. Samples from other counties were obtained from a blood bank and were anonymized. Seventeen (6.8%) samples were seropositive for antibodies against at least one pathogen: five for A. phagocytophilum, eight for B. burgdorferi, and four for Rickettsia spp. Women and people aged 26-35 had higher seroprevalence compared to other demographic groups. Santa Cruz County had no seropositive individuals, northern Central Valley counties had three seropositive individuals (all against A. phagocytophilum), and Humboldt County had 14 (all three pathogens), a significant, four-fold elevated risk of exposure. The Humboldt County questionnaire revealed that a bird feeder in the yard was statistically associated with exposure to ticks, and lifetime number of tick bites was associated with increasing age, time watching wildlife, and time hiking. Three-quarters of respondents were concerned about tick-associated disease, 81.0% reported experiencing tick bites, and 39.0% of those bitten reported a tick-borne disease symptom, including skin lesions (76.4%), muscle aches (49.1%), joint pain (25.5%), or fever (23.6%).

Despite high levels of concern, many individuals who had been bitten by a tick were not tested for a tick-borne pathogen, including those with consistent symptoms.

We highlight the need for further research and dissemination of information to residents and physicians in Northern California regarding tick-associated disease, so that appropriate medical attention can be rapidly sought and administered.

Again, the numbers are going to be much higher as they used the abysmal serology testing which tests for antibodies – not the organisms.
