Objective –  Paired serum and cerebrospinal fluid (CSF) specimens were investigated for Chlamydia pneumoniae ‐specific oligoclonal bands (OCBs) to determine band specificity in multiple sclerosis (MS). Material and methods –  Serum and CSF samples were collected from patients with relapsing–remitting MS ( n  = 56), other inflammatory ( n  = 18) or non‐inflammatory ( n  = 15) neurologic diseases, and from 10 healthy controls. OCBs were determined with affinity immunoblotting of C. pneumoniae ‐specific IgG onto antigen‐coated nitrocellulose paper after protein separation with agarose isoelectric focusing. Results –  Chlamydia pneumoniae ‐specific OCBs were present in 5 of 56 patients with MS, and in 3 of 18 patients with other inflammatory neurologic diseases. Conclusions –  The intrathecal production of C. pneumoniae ‐specific oligoclonal IgG occurs in a minority of patients with MS. This intrathecal anti‐ C. pneumoniae reactivity is likely part of a polyspecific humoral immune response in MS.
