title: Immunotyping of Chlamydia psittaci by indirect immunofluorescence antibody test with monoclonal antibodies.
abstract: Monoclonal antibodies against pigeon and budgerigar strains of Chlamydia psittaci were used to classify the immunotypes of C. psittaci strains by an indirect immunofluorescence antibody (IFA) test. Thirty-three C. psittaci strains from pigeons and 24 from budgerigars were divided into three immunotypes (P-I, P-II, and P-III) and (B-I, B-II, and B-III), respectively. Two strains from human psittacosis patients were identified as P-III and B-I, coinciding with the epidemiological evidence of each human infection. Two strains from psittacine birds, a parrot and a parakeet, were identical to the B-II immunotype. Other mammalian strains were quite distinct from avian strains in their IFA reaction with the monoclonal antibodies.
