Emerging Lyme Disease Co-infection: Chlamydia Pneumoniae

Emerging Lyme Disease Co-infection: Chlamydia Pneumoniae

Chlamydia Pneumoniae, also known as CPN, is a fast emerging Lyme co-infection with very similar symptoms.

In fact for some who remain very sick and have yet to receive a positive Lyme diagnosis, CPN is something that should definitely be tested for.

The following description was taken from a blog on www.cpnhelp.org the only CPN forum I could find. It is important to note the extreme similarities in symptoms, reaction to antibiotics and even the close association with Babesiosa.

Many who are familiar with both diseases have said, “It’s not a far stretch to insert CPN everywhere lyme/borrelia is inserted” Chlamydia Pneumoniae (Cpn) is a tiny bacterium which is most often noted for causing a form of pneumonia. Up until the 1970′s it was not even isolated and was mistaken for a virus (its discovery is an interesting story and can be found here: http://www.washington.edu/research/pathbreakers/1989a.html).

“It was not until 1989 that J. Thomas Grayston and his associates named it as a separate species of the Chlamydiae. Cpn is very difficult to culture and so, without modern lab techniques, also to study. It is an intracellular bacterium, which means that it invades the body cells, and it is an obligate parasite, which means that it cannot supply it’s own energy source and so takes over the energy machinery of the body cells it invades, depleting them and leaving the host cell less functional.”

“Cpn has been implicated in a wide variety of diseases and is seen by some researchers as a causal factor in particular disease such as Multiple Sclerosis, Chronic Fatigue, Asthma, Rheumatoid Arthritis, Fibromyalgia, Chronic Refractory Sinusitis, Cardiac disease, Interstitial Cystitis, Prostatitis, Alzheimer’s disease, Crohn’s disease, Inflammatory Bowel disease, and others.”

CPN is also commonly accompanied by Secondary Porphyria and Micoplasma.

If you suspect you may have CPN or CPN complications, ask your doctor to test for PCR testing, especially that which is referred to as nested-PCR testing, is considered to have the highest sensitivity and to be most objective source of serology testing for Cpn.

    If I recall correctly, the same antibiotics used to treat Babesiosis will also treat CPN… is that correct? If the timelines are about the same for these two pathogens, then taking Mepron and Zithromax should probably kill both at the same time. What else can be used to treat CPN and how long does one generally treat it?

      It has been a long time since I’ve been on the CPN.org site but my sister doesn’t tolerate abx at all so she has had a very long rough go of trying to get rid of it and her immune system has tanked on her a number of times in the past 15 years so my knowledge of CPN is second hand. However when we swap symptoms I am amazed at how similar they are, and the CPN crowd is the only other group I know of that uses the term “herx” the way chronic Lymies do. It seems to me they can diagnose CPN more accurately but have a similar issue with co-infections which makes recovery far more complex. I will have to do an update on CPN when I get my blog back together…thanks for taking the time to comment!


    Could you tell me where to go in the UK to be tested for CPN and who could give treatment for this. I also have Lyme Disease with co~infections so am very complicated?

    • Jenna Smith says:

      The best place to find out would be CPN.org…and my sister is very private about her health – she doesn’t visit with forums or other groups mostly because she has 3 young children to take care of. I will say that she has done the best with a gluten free diet, juicing with organic fruits and veggies all day long, lots of Vitamin B12, D and Iron (she’s always anemic which is something I am borderline but nothing like her) – lots of rest when she can…but I will talk to her because I am a firm believer in having someone who can understand what you are going through. Do you have children? I have so much respect for her…she is the BEST Mom, I just don’t know how she gets out of bed…
      I hope you have good support Jane, I know CPN.org has a wonderful forum for people who need to reach out and I am pretty sure there are others there with Lyme as well.

    Hello! I was diagnosed 2 years ago with Lyme through IGENEX labs. I was in treatment for about 6 months and stopped on my own. (not smart, I know) Anyway, I became symptomatic again recently after I had an engorged tick on my belly. The tick just came back “negative” for Lyme but my LLMD tested several things. Everything came back “negative” except for Chlamydia Pneumoniae! I am now shocked and devastated to learn I have yet another battle ahead of me! My question is did the TICK give me this as well as Lyme? I know that I was hospitalized for 13 days back in 2004 with double pneumonia but why would I just now be finding out about this CPn after another tick bite? *scratching head* Thanks for any input!

    • Jenna Smith says:

      I am so sorry Kim –

      You probably had CPN before this last tick bite but who knows – these tests are not reliable in any way. I would say you’ve been sick for as long as you have had “the symptoms”. For everyone the collection of symptoms will be unique and I know that CPN is very much like Lyme but also a co-infection (ticks spread CPN along with Lyme, Babesia, Bartonella, Mycoplasma, Herpes, Toxemia and many others.) You can’t go back in time but you should definitely get back on abx with a strong probiotic – that is my opinion – I am NOT a licensed medical practitioner but you need to find a good one fast. CPN.org will give yo lots of info too but you have to kill ALL of the infections – parasites, candida (yeast) and mold too. If you need help finding a good doctor let me know.
