The Scientific Connection Between STARI & Chronic Lyme

The Scientific Connection Between STARI and Chronic Lyme

By Allison Caruana

President, The Mayday Project

The organism that causes chronic Lyme disease and STARI/Master’s disease is physiologically similar, but until now has not been defined. Borrelia burgdorferi (Bb) is the carrier of but not the cause of the longstanding symptoms of what is known as chronic Lyme disease. Borrelia burgdorferi B31 is a rickettsial agent. Helical spiroplasma that carries the Pandora Virus (circular plasmid 26), which transfers mutant virophages to the host, is the causative agent of chronic (not early) Lyme disease, as well as STARI/Master’s disease.

In an interview with Gary Engelman, Dr. Willy Burgdorfer made two important claims. The first, borrelia was the agent of Relapsing Fever, but is not the agent of Lyme disease.13 Relapsing Fever is a different species of borrelia2, whereas Borrelia burgdorferi B31 is Spiroplasma apis.21 Dr. Willy Burgdorfer goes on to state that these are spirochete-like organisms and that up until his discovery of Borrelia burgdorferi, spirochetes had never been found to exist in deer ticks.13 The same is not true for spiroplasmas, which are common in arthropods.16 Spiroplasmas are known to cause symptoms identical to Lyme disease, i.e., arthritis, heart murmur, swollen knee, and more.14 

The Borrelia associated with Lyme disease are unlike other borrelia, as these organisms are known for an amorphous slime layer. Historically, this feature has been associated with spiroplasmas, not spirochetes.17, 20, 29, 30 Spiroplasmas (family spiroplasmataceae, order mycoplasmatales) are comprised of a group of helical prokaryotes whose external morphology differs from the spirochete. The spirochete is defined by an internal skeletal framework rather than an external peptidoglycan-containing cell wall.15 The organism we call the Bb spirochete has blebs and granules,6 which are attributes of spiroplasma and mycoplasma that occurs as a morphological response to environmental stress- which produce uncultivable mycoplasmas.20, 23, 29, 31, 32

Borrelia burgdorferi B31 is believed to be a pleomorphic spiroplasma within the family of Spiroplasma apis. This would explain Dr. Willy Burgdorfer’s statement regarding the “spirochete-like organisms” that are found in ticks.13 Additionally, Borrelia burgdorferi contain 12 linear and 9 circular plasmids, some of which have been determined to harbor mutant “bacteriophages”.4, 11, 12, 18 In theory, the term bacteriophage could be exchanged for a more proper term: “virophage”. This suggestion comes on the basis that the term “plasmid” and “chromosome” can be interchanged for “Giant viruses”.19 The circular plasmid 26 (cp26) of Borrelia burgdorferi contains 27 phages7, 11, 12 of which 19 are mutant phages (FIG. 6).18 If cp26 was not a Girus (Giant Virus), the plasmid would have burst due to the infection of a natural phage. However, cp26 is the only plasmid to be found in all isolates of Bb that has not experienced gene loss.7, 18 

It is important to note that convoluted terminology has been previously experienced in discussions around Bb. The terms “spiroplasma”, “mycoplasma” and “spirochete” are used interchangeably,31 so this is understandable for “Giant virus”, “Plasmid” and “chromosome”. The Giant Virus is also said to be associated with amoebas, however, there are amoeba-associated bacteria which can exploit common mechanisms.26

Dr. Willy Burgdorfer reviewed and tested patient blood samples from Dr. Anderson for C9P09, which is a rickettsial helical Mycoplasma; P09 being a Rickettsia bellii and C9 being a Mycoplasma (FIG. 2).35 This is further supported by the theory that an endosymbiotic infection produces spirochetes that are uncultivable Mycoplasmas, which are also called spirochetes. 1, 22, 31, 32 

The “Swiss Agent” is documented by Dr. Willy Burgdorfer (FIG. 3),25 who also wrote a speech on “Pandora’s Box”.5 Although the Swiss Agent paper is associated with the suspected African Swine Flu, Dr. Willy Burgdorfer appears to be famous for leaving clues throughout his work regarding Lyme disease. Upon reviewing the structure of the Lyme disease “Swiss Agent” and the “Pandora Giant Virus”, there is a striking resemblance that deserves further examination. This theory is supported by presentations FIG. 3 & 4, which show similar organisms. Additionally, this is supported by phylogenic information found on www.giantvirus.org regarding the genes found within the giant viruses (FIG. 5). 

Giant viruses are also known to harbor a symbiotic colony of Sputnik or mutant virophages in archaeal viruses (plasmids).9, 27 These phages are found in cp26 and the multiple cp32’s, which are worthy of additional research.4, 7, 11, 12, 18  From a virology standpoint, the only way these phages could coexist in a symbiotic relationship within the bacteria would be if the plasmid was in fact a giant virus- able to transduce genetic information to ensure the survival of the host and the organisms.11, 12 The phages carried in cp26 are the only ones to be found in all isolates and never lost.7

The giant virus also brings into question why STARI and Master’s disease is noted by Dr. Willy Burgdorferi to be a Lyme disease agent that is found in Amblyomma americanum (FIG. 1). This is supported by the fact that flaB (a transcription gene for Bb) was found in all STARI patients he had tested.8, 11 The Lyme- like organism is a mimicking microbe that by scientific definition is a giant virus.9 The scientific differentiation has been made between “Early Lyme disease” and “STARI”/“Master’s disease”, but not “chronic Lyme disease”.24 There are numerous morphological similarities between chronic Lyme disease and STARI/ Master’s disease. In both organisms, uncultivable spirochetes can be found, in addition to the transcription gene, flaB being found in STARI. Being that flaB is a promoter gene of cp26,10 the giant virus of Borrelia burgdorferi would be found in STARI patients. 

It is suspected that the rickettsial agents associated with the Lyme disease organism assists in a morphological transformation of the plasmid within the spiroplasma.2 This transition could cause the morphological transformation of the bacterial infection of early Lyme disease into the chronic Lyme/ STARI/ Master’s disease organism of uncultivable spirochetes.3, 31 In addition to the transformational aspect of early Lyme disease to chronic Lyme disease, we have a variety of ticks believed to carry this organism (FIG. 1). It is possible that the giant virus is still transferred to the patient, despite some ticks carrying an anti-borrelial agent in their salvia that eliminates the spiroplasma.1, 8, 24 All evidence supporting the theory that cp26 is in fact responsible for the uncultivable spirochetes found in human subjects,3 potentially the same for all three diseases in question in this research study.

Former U.S. Senator Dies of Powassan Virus

Flags in NC lowered to half-staff to honor former US Sen. Kay Hagan

October 28, 2019

— Tributes poured in Monday from North Carolina and Washington, D.C., praising former U.S. Sen. Kay Hagan, who died after battling a lengthy illness, her family and Democratic party leaders confirmed to WRAL News. She was 66.

“We are heartbroken to share that Kay left us unexpectedly this morning,” her family said in a statement. “Kay meant everything to us, and we were honored to share her with the people of North Carolina, whom she cared for and fought for so passionately as an elected official.

“Most of all, we already miss her humor and spirit as the hub of our family, a role she loved more than anything. Nobody could light up a room and make people feel welcome like Kay,” her family said.

Hagan, a Democrat who was seen in public this weekend at a fundraising event for former Vice President Joe Biden, was elected in 2008 and served one term before she was defeated by Republican U.S. Sen. Thom Tillis during a bruising contest for the seat in 2014.

Gov. Roy Cooper ordered U.S. and North Carolina flags lowered to half-staff through sunset Tuesday to pay tribute to Hagan, who was born in Shelby.

Hagan served 10 years in the state Senate, representing Guilford County, before besting Republican U.S. Sen. Elizabeth Dole in 2008. Before entering politics, Hagan worked as a lawyer and in the banking industry.

In 2016, Hagan was diagnosed with Powassan virus, an illness transmitted by ticks. According to experts, there is no vaccine or antiviral drug that can combat the ailment.

As word began to spread about her death, the condolences started pouring in for Hagan.

“The world is a little grayer since we lost this amazing woman and dear friend today,” Claire McCaskill, former U.S. senator for Missouri, tweeted.

Biden also tweeted his condolences.

“Kay Hagan was a courageous soul who lived every day of her too-short life with incredible dignity and character, even as the days became more difficult physically,” Biden’s tweet said. “Jill and I are deeply saddened by this news and extend our condolences to her entire family.”

Republican 6th District Congressman Mark Walker, who represents the Greensboro area, said Hagan worked tirelessly for North Carolina.

“Sen. Hagan was dedicated to serving North Carolinians and especially to the men and women of the Armed Forces in America’s most military-friendly state,” he said in a written statement.

Cooper recalled the days when they both served in the state legislature.

“I’ve known Kay since our days in the legislature together,” Cooper’s statement said. “Kay was a fierce advocate for North Carolina, and she represented our state with courage and grace her entire career.

“She made it a mission to inspire young people, especially young girls, to enter public service, and she served as a role model to so many,” Cooper said.

Hagan rose quickly in the General Assembly to become one of the Senate’s primary budget writers under former Gov. Mike Easley. Easley had to negotiate the state budget with Hagan for many years, and he said she was warm but drove a tough bargain.

“She was such an angel and delightful personality, but at the same time, she could be just as tough as nails,” Easley said. “I remember her on [Senate] Appropriations standing up to a lot of the older guys in the legislature.”

Those who served in state government with her said news of her passing hit close to home.

“Notwithstanding the fact that we are of different parties and had philosophical disagreements, I always had a warm and friendly relationship with her,” Senate President Pro Tem Phil Berger said, noting they served in the Senate together for eight years and both represented Guilford County.

Tillis, who defeated Hagan for the Senate seat he now holds, said in a written statement, “Susan and I are absolutely heartbroken by Senator Kay Hagan’s sudden passing, and we extend our condolences and prayers to her loving family and many friends. We join all North Carolinians in remembering her dedicated and distinguished record of public service to our state and nation.”

Republican U.S. Sen. Richard Burr praised Hagan’s dedication to North Carolina.

“Kay dedicated much of her life to serving North Carolina, and she will be remembered for her tireless work on behalf of the home and the people she loved,” he said in a statement. “In our time as Senate colleagues, we worked across the aisle together frequently on issues that we both knew would determine what type of country our children would inherit.”

“…Say — what’s that?”

“Nothing but a tick.”

“Where’d you get him?”

“Out in the woods.”

“What’ll you take for him?”

“I don’t know. I don’t want to sell him.”

—Tom and Huck, in Tom Sawyer

Ticks were evidently so rare in Samuel Clemens’ Hannibal that a single live specimen had value enough to tempt Tom Sawyer to part with his newly shed tooth. Matthias Leu says it was the same in the Switzerland of his more recent youth.

“When I was a boy, I spent all my time in the forest,” Leu said. “I never saw one tick. And in Switzerland now, you should not leave the trails because there are so many ticks. So, it’s not just in North America; it’s global.”

**Comment*

Great read which exposes the fact that little is known about the Ehrlichia chaffeensis bacterium which gives similar symptoms as Lyme disease. According to biologist Matthias Leu, “There probably has been a lot of ehrlichiosis that was misdiagnosed as Lyme.” Leu and his colleagues studied the habitat of the Lone Star Tick and found that forest fragmentation causes more edges which deer love, giving ticks an easy meal.

Leu explains that deer are “competent hosts,” serving not only as a meal for the tick, but also a reservoir for ehrlichiosis, capable of infecting the next feasting tick with Ehrlichia chaffeensis. He states that fawns and yearling deer are especially important in transmission of the bacterium.

According to this study, health providers often fail to consider ehrlichia when treating tick borne infections:  https://www.sciencedaily.com/releases/2018/10/181001171202.htm

“The failure to test for Ehrlichia, even as more and more evidence suggests that the infection may be just as common as other endemic tick-borne diseases, appears to impact patient care with antibiotics prescribed less frequently when testing is not ordered.”

Researchers Conclude Asian Longhorned Tick Contributes Minimally to Lyme Disease in the U.S.

Original article

Failure of the Asian longhorned tick, Haemaphysalis longicornis, to serve as an experimental vector of the Lyme disease spirochete, Borrelia burgdorferi sensu stricto

Under a Creative Commons licenseopen access

Abstract

The invasive, human-biting Asian longhorned tick, Haemaphysalis longicornis, was detected in New Jersey in the eastern United States in August of 2017 and by November of 2018 this tick had been recorded from 45 counties across 9 states, primarily along the Eastern Seaboard. The establishment of H. longicornis in the United States has raised the questions of how commonly it will bite humans and which native pathogens may naturally infect this tick. There also is a need for experimental vector competence studies with native pathogens to determine if H. longicornis can acquire a given pathogen while feeding, pass it transstadially, and then transmit the pathogen in the next life stage.

In this experimental study, we evaluated the vector competence of a population of H. longicornis originating from the United States (New York) for a native isolate (B31) of the Lyme disease spirochete, Borrelia burgdorferi sensu stricto (s.s.).

In agreement with a previous experimental study on the vector competence of H. longicornis for Borrelia garinii, we found that uninfected H. longicornis larvae could acquire B. burgdorferi s.s. while feeding on infected Mus musculus mice (infection prevalence >50% in freshly fed larvae) but that the infection was lost during the molt to the nymphal stage. None of 520 tested molted nymphs were found to be infected, indicating that transstadial passage of B. burgdorferi s.s. is absent or rare in H. longicornis; and based on the potential error associated with the number of nymphs testing negative in this study, we estimate that the upper 95% limit for infection prevalence was 0.73%.

An Ixodes scapularis process control showed both effective acquisition of B. burgdorferi s.s. from infected mice by uninfected larvae and transstadial passage to the nymphal stage (infection prevalence of 80–82% for both freshly fed larvae and molted nymphs). We also observed that although H. longicornis larvae could be compelled to feed on mice by placing the ticks within feeding capsules, attachment and feeding success was minimal (<0.5%) when larvae were placed freely on the fur of the mice.

We conclude that H. longicornis is unlikely to contribute more than minimally, if at all, to transmission of Lyme disease spirochetes in the United States.

Transmission can still happen and if you are the sorry sucker it happens to – it makes all the difference in the world.  Here’s the deal – ticks are not your friends. Take each and every tick bite as seriously as a heart attack.  Little is known about the Asian Longhorned tick but in Asia it’s bite KILLS 15% of those whom contract it. Don’t take this lightly.

Excerpt:

Several other human pathogens have been detected in the ticks, but it’s not clear the Asian longhorned species are able to transmit them to humans. They include Anaplasma, Ehrlichia, Rickettsia, and Borreliaspecies. Lyme disease is caused by Borrelia burgdorferi bacteria.

She warned that the organisms are present in states where longhorned ticks have been found and that it’s possible that the tick—known to be an aggressive bitermight be able to transmit Heartland virus, given its close relationship to SFTS virus.

Pritt said it’s clear that the invasive species is here to stay for the foreseeable future, and next steps should include public awareness campaigns that incorporate the new information, easy-to-use resources for labs to identify the tick, and more research to understand the implications of the new findings.

For a great read on this aggressive biter which can clone itself and is found in sunny open locations:   https://madisonarealymesupportgroup.com/2018/09/12/three-surprising-things-i-learned-about-asian-longhorned-ticks-the-tick-guy-tom-mather/.  This picture demonstrates how if you brush against a blade of grass a literal cluster bomb of ticks explodes onto you.  To downplay this is really short sighted.three_surprising_4.png-2
