P. Gingivalis and citrullination (note that this was the HLA-DR1 group but we are looking at it now to compare with mycoplasmas)
http://www.roadback.org/forums/topic/pathogens-and-seropositive-ra/
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4131749/

note that arginine deaminase inhibits gingivalis attachment
https://www.researchgate.net/publication/233931217_Arginine_Deiminase_Inhibits_P_gingivalis_Surface_Attachment

I don't think that only gingivalis is an issue in RA because some mycoplasmas use arginine and attach to cells using arginine too

some mycoplasmas attach to cells and use arginine
https://books.google.com/books?id=YmEoAv_eQ3EC&pg=PA154&lpg=PA154&dq=mycoplasma+attach+arginine&source=bl&ots=ws1fi5f34s&sig=mHWiUkK4eX4A65EMHGpq8VKq2Es&hl=en&sa=X&ved=0ahUKEwismdXG4JbQAhVE02MKHUEkDIwQ6AEISTAJ#v=onepage&q=mycoplasma%20attach%20arginine&f=false

(under citrullination : arginine becomes citrulline)

problem: takayasu and hla-dr6....that's a mycobacteria?

patients with pulmonary tuberculous has antibodies to cyclic citrullinated proteins

This would mean that late onset MS would be mycobacteria with HLA-DR6
