Every year science learns more and more about how bacteria affect the human body, but what do we really know about Borrelia Burgdorferi, the bacterium that causes Lyme and Lyme-like illness?
A Little Background
Dr. Kenneth Liegner says it best,
"It took medical science roughly 500 years to gain a good understanding of syphilis. We are but 40 years in to Lyme disease, caused by a spirochete considerably more genetically complex than Treponema pallidum, the organism causing syphilis.”As I pointed out in an earlier post, there are 3 Basic Stages of Lyme Disease, and a 4th somewhat controversial stage or "syndrome" that occurs after antibiotic treatment. Stage 1-Primary Lyme (occurs days to weeks after infection); Stage 2-Secondary Lyme (occurs 3 weeks to 3 months after infection); Stage 3-Late Stage Lyme (occurs months to years later); Stage 4- Post Treatment Lyme Disease Syndrome aka PTLDS (Chronic symptoms that linger after a 2-4 week course of antibiotics).
The last stage, or syndrome, may be defined differently depending on which infectious disease theory you subscribe to. In the 'World of Lyme Research' there are basically two different theories:
The idea of bacterial persisters were first described by Joseph Bigger in 1944. In his 2007 Article, Dr. Kim Lewis of Northeastern University, reviews Persister Cells, Dormancy and Infectious Disease. Dr Lewis says, "Bigger discovered that penicillin lysed a growing population of staphylococcus ssp., but that a small number of persister cells, which were not simply antibiotic-resistant mutants, inevitably survived..." Bigger found that the E.Coli bacteria that survive after exposure to ampicillin form mutants that grew into persister cells. These persisters were able to survive at 1000 times the rate of non-mutants. Dr. Lewis suggests that dormant persister bacteria may play a much larger role in recalcitrant infectious diseases than previously thought.
- Says that the continuation of symptoms that persist after treatment for a Lyme Disease infection are caused by damage to the immune system (or other yet to be defined bodily tissues); the other
- Says that the chronicity of symptoms are a result of lingering persistent infection caused by Borrelia's ability to evade antibiotics and the immune system.
What Are Persister Cells?
”About half of infectious diseases that are difficult to treat with antibiotics are not due to resistance but persisters” ~ Kim Lewis, 2012Ed Yong does a fantastic job of describing persister cells in his 2012 New Scientist article entitled Sleeper Cells: "Our strongest antibiotics are being thwarted by bacteria that lie dormant, only to bounce back unharmed once the pressure is off." In this article Yong interviews Dr. Kim Lewis:
What is going on? It seems that this dormant state evolved to allow bacteria to cope with harsh environments, such as low oxygen levels, lack of nutrients or adverse temperatures. Today, it allows them to shrug off antibiotics.
Lewis describes them as the ultimate adversary. "Their function is to be not killed," he says. "They don't do anything else. They don't grow. They don't propagate. They don't do anything except survive."

Willy Knew What He Was Talking About
Accordingly, B burgdorferi converted rapidly to cystic forms when transferred to spinal fluid. No normal spirochetes were left after 24 hours of incubation at 37° C; all were converted to cysts. When these cystic forms were transferred to a rich (BSK-H) medium, the cysts were converted back to normal, mobile spirochetes after incubation for 9 to 17 days.
These most recent findings do confirm the development of membrane-derived cysts, blebs, spherules, vesicles and the potential transformation to motile, helical spirochetes, not as part of a complex developmental cycle -- as postulated by Dutton and associates -- but rather as a "survival mechanism" of spirochetes to overcome or escape unfavorable conditions.
It is tempting to speculate, however, that the survival mechanism of spirochetes is responsible for the diverse pathology of these organisms as well as for their ability to survive as cystic forms thereby producing prolonged, chronic and periodically recurrent disease.
Current and Ongoing Research
Norvect did a great interview with Dr. Zhang in September 2015 where he discusses the similarities between Tuberculosis and Lyme persister cells and the difference in treatment approaches to Early and Late Stage Lyme Disease. You can watch the short Video here.
Basically what you need to know is that antibiotics are designed to target different forms of bacteria--gram negative, gram positive, those with cell walls, and those without cell walls. Antibiotics can also be used to target bacterial proteins or interfere with the bacterial enzymes. Doxycycline for instance, is microbiostatic and relies on immune clearance of static bacteria in order to work.
Because B.b. evades the immune response, like a stealth bacteria, doxycycline alone may not be the most effective antibiotic for treating Lyme, especially in immunocompromised individuals. Most antibiotics are only able to kill bacteria during their active growing phase. Because B.b. can survive for many months in a dormant phase in places like deep tendons, connective tissue, joints and central nervous system without nutrients, many types antibiotics will be ineffective when used alone.
At any given point in time the Lyme bacteria will be present in multiple "pleomorphic" forms. Science has known that Treponema palladium, the bacteria that causes syphilis also has the ability to form atypical cystic forms allowing it to lay dormant for years before resurging to attack the nervous system. This is not a new discovery. Many bacteria do this, for example, Tuberculosis, Gonorrhea, and Mycobacteria like the one that causes Leprosy.
Pleomorphic forms of B.b. (a) spirochete, (b) bleb, (c) round body, (d) biofilm (source) |
So what happens when you treat one of these bacteria with the wrong or too weak of an antibiotic? They can form resistance to the antibiotic and/or persistent forms of bacteria that will lay dormant until such time that the environment is favorable for them to grow again. Ying Zhang likens this to using a lawn mower for killing weeds.
There are multiple studies which have proven the Lyme Bacteria are capable of surviving in animals after a standard course of antibiotics. In fact, there is a preponderance of evidence from multiple labs, on multiple species using multiple drugs (doxycycline, amoxicillin, azithromycin, ceftriaxone, tigecycline) all with similar results of visible persistent infection in tissues after antibiotics. (UC Davis -Bartholdi, Hodzic et al.; Yale Univ- Bockenstedt et al; Univ Tuku- Yrjanainen et al; Cornel Univ- Straubinger et al; Tulane Univ- Embers et al.)
Can We Apply TB Science to Lyme Science?
In his paper Dr. Zhang reveals Two triple drug combinations with highest activity against Borrelia burgdorferi Persisters: (link here)
- Artemisinin/Cefoperazone/Doxycycline
- Sulfachlorpyridazine/Daptomycin/Doxycicline
Note that both of these Drug combinations are from FDA approved libraries. The next step would be to apply these in animal models and human clinical trials to test the treatment theory outside of the laboratory. Hopefully, it won't be long before we have more data.
As Dr. Zhang presented his findings on Saturday, May 14, 2016 at Massachusetts General Hospital during a conference on "Lyme Disease and Other Tick-borne Illnesses..." I can't help but wonder, was the Medical Community listening?
Great blog thanks for this post one or two points you have pointed me to research papers I wanted to find but hadn't had time.
ReplyDeleteThanks for reading my blog Joanne and for following me on twitter.
DeleteGlad to connect,

Great post! I felt the same way when the Johns Hopkins study came out about persister cells. Um, didn't we ALREADY discover that like 20 years ago? The one thing I don't agree with Zhang is that the two camps are focusing on different aspect of the disease and that they will come together. The most influential doctors at the IDSA say there is no persistence, there is no such thing as the disease causing the later symptoms (though they now no longer deny the symptoms exist with the growing population of those who've failed 2-4 weeks of doxy). It concerns me that the IDSA willfully ignores hundreds of peer reviewed research (even Willy's 1999) supporting persistence and makes me question the motivation behind such blatant disregard. That particular theory supports funneling all funds to a vaccine instead of research to help those that need help with persistence. Whereas Zhang would love to see more research to help the chronic population, the IDSA does not. I don't think that ILADS denies the various stages, such as early stage, and in fact proposes prophylactic approach to being bitten by a tick in an endemic area. It's interesting to see some researchers like Zhang trying to ride the middle road not to tick off (no pun intended) those in the IDSA.
ReplyDeleteOn another note, there are hundreds of diagnosis where patients are often getting 2nd and 3rd opinions on diagnosis and/or how to treat. That is often the first thing people do when they get a severe diagnosis. Why in the world is Lyme so controversial in this manner? Why is it so taboo to have another MD offer a 2nd opinion and treat the patient to the best of his ability and knowledge? Lyme disease is no different than any other disease in that manner and yet it's been put in this political struggle in which patients are mocked and doctors are witch-hunted. Why? To me it comes back to the same motivation of a (now small) group of MD's and scientists.
Thanks for this article. The education on persistence versus resistance was very useful!
Thank you for reading my blog. I'd just finished reading a text book on the history of Tuberculosis when Zhang's study came out. I'd also just happened upon the 1999 Conference with Willy's Keynote speech by chance. It's unbelievable, to me that these facts on persisters have been known for 20 years and not taught in medical schools. Many of the doctors that were at that conference 'got it' and many of them are still practicing today.
DeleteI've had a lot of doctors tell me that TB is "very different" than Lyme, but when you look at persisters as a mechanism for chronic illness, I see very little difference. The more I study the more I think science will eventually prove infection as the trigger for the vast majority of illness (eg. Fibromyalgia, ME, CFS, MS, Lupus, PANDAS and the list goes on...) We know that HPV causes cervical cancer, H-Pylori causes stomach cancer, untreated Lyme causes arthritis...why is it so hard to believe that under-treated Lyme causes Chronic Lyme Disease? (ready paragraph on What's causing ME/CFS here: http://tenaciouspt.blogspot.com/2015/07/chronic-fatigue-syndrome-myalgic.html)
Zhang is all about the Yin and the Yang. I like his approach and do think we still have a lot to learn. There are extremists in both Camps. The solution is going to be a balanced approach somewhere in the middle- hopefully a targeted combination therapy, and as we learn more the treatment needs to continue to evolve. We should never think we have the final answer. Unfortunately, Lyme treatment got stuck 30+ years ago. We need to unstick it.
I agree on the 2nd and 3rd opinion's. It is totally acceptable for any other illness. I am fortunate in that currently all of my daughters doctors work together. Even her pediatrician who knew nothing about Lyme, stuck with us when we began treatment with an LLMD. Some of the specialists we saw were more closed minded but for the most part we've run into lack of knowledge of how to treat tick-borne diseases versus a lack of desire to help. Ironically, the only doctor that said absolutely "no" it's not Lyme was the Infectious Disease Specialist at our nearest children's hospital simply because she was missing 1 band on the Western Blot. Every other doctor she's seen was much more open minded.
Anyway, thanks for the thought provoking comment.
All Best Wishes, Lonnie
Missing a band on a Western Blot? So I suppose a pregnancy test can mean you're only "a little bit pregnant?" sigh. So tired of hearing that excuse of missing a band means no infection. I have had good and bad experiences with non lyme docs... some asking for help for patients who they know have lyme and want to know where to send them. others insisting i don't have lyme. We got stuck 30+ years ago because of things changing in pieces of bacteria being able to be patented and intellectual property. Patients got hurt and are getting hurt today because science isn't shared or being collaborated. Patients must be their own advocates and be as educated or more than the basic MD. Weird world we live in. Ultimately though, your health comes down to your own decisions. Knowledge is power to make the best decision for your specific case, Lyme or not. Even in every single case of Lyme & Co, it still comes down to more than just the infection, but the knowledge of the individual's genetics, environmental toxin exposure and diet sensitivities. It's a puzzle for every single case and that ultimately is not good for the healthcare industry who cannot put Lyme in a box with a specific treatment protocol. Sadly, none of this would be such an issue if Lyme is diagnosed very early and not sloughed off as "just a nasty tick bite and you don't have any infection if no bulls eye and a negative Elisa." Most of the chronic lyme cases are late diagnosis, not just failed early treatment cases. It's a complex disease and our healthcare system hates complexity. LOL. Take care, Julie
