Ok, not easy to explain Cpn in one go... Basically Cpn (Chlamydia Pneumoniae) is a bacterium transmitted through cough and sneezes which does not cause the majority of people more than a flu like episode. However some people are much more affected than others, ie some susceptible people will suffer from MS or CFS, or RA or like me Alopecia, to name but a few, as a result of this infection.
It is difficult to detect and difficult to treat because of its reproductive cycle and its ability to lie dormant inside the cells of your body. For more information about this bug you might find it useful to go to

Simply put it is something like tuberculosis, difficult to treat and eradicate. Unlike tuberculosis it 'kills you more slowly' and in the meantime incapacitates some unlucky sufferers.
It is estimated that up to 70% of the over 50 population are suffering from some Cpn related ailments.
The protocol used to treat this disease consists of two antibiotics taken simultaneously which stop the beast from replicating. When these are well tolerated another is added intermittently that kills some of the bugs. It is important not to kill too many of them at one go, was the dead bacteria are toxic and can make you quite ill, hence the length of time it takes to treat it.
This is just a very sketchy explanation... It is a complex beast and we are complex organisms so there is a lot to learn.
Hope this helps you on your way...
