Comparison of antibody levels against human and bacterial HSP60 in SpA patients. Antibody levels in serum samples from 2006 against human HSP60 (n = 39) were compared groupwise with IgG1 (A), (B) and (C) and IgG3 (D), (E) and (F) antibodies against bacterial HSP60. Lines are drawn between antibody levels for human HSP60 and HSP60 of Salmonella enterica Enteritidis, Chlamydia trachomatis and Campylobacter jejuni HSP60 for each patient. Serum levels below 2 μg/ml are shown in gray.
