| Abstract: | Data on specific antibodies to the bacterial antigens of Yersinia enterocolitica (serovars 03, 09) and Proteus mirabilis in rheumatoid arthritis (RA) patients are presented. According to the data of some researchers, these organisms play some role in the pathogenesis of RA. The highest level of IgG antibodies to Y. enterocolitica antigens of both serovars was noted. The activity of specific IgG antibodies to serovar 03 was higher than that to serovar 09. In the sera of RA patients with P. mirabilis antgens the activity of IgM antibodies was higher. |
