Thanks Dr,
had a bit of a read up on polymyositis, another 'auto-immune disease' or should I say a disease that isn't understood yet.
Interesting links to Lyme disease and that will mean CPn as well as I thought!
Seems there are many diseases that are thought to be virus or bacterial linked but the tests are not up to the task 'yet'.

From back in 1999 when CPn was first linked to many diseases of 'auto-immune' origin, time has supported this finding and there are hundreds of links where 'auto-immune is found to be incorrect as a dx'.
For those with what I now call 'Bacterial MS' since being on the Wheldon/Paul Paul Thibault protocol and experiencing positive changes in my MS, this article brings more awareness to the way the infection spreads in ones system.
"If you have inflammation, a spider bite, a viral joint infection, viral meningitis or encephalitis, it doesn't matter what it is, if a Chlamydia-infected cells happens to end up in that inflamed area, you may have just started yourself a Chlamydia farm."
RA is also a co-disease for CPn sufferers.
