Chlamydia psittaci was isolated from the spleen of a moribund white-winged dove (Zenaida asiatica). The isolate was serotyped as the serovar B that is commonly isolated from pigeons. A fourfold increase in the titer of antichlamydial IgM activity occurred in that bird in paired serum samples tested by chlamydial elementary body agglutination (EBA) and a greater than or equal to fourfold decrease of IgG occurred by direct complement fixation (DCF). The increases or decreases of EBA and DCF titers in other clinically ill birds that were treated with tetracycline varied, as normally occurs in cases of avian chlamydiosis. Titers in clinically normal birds were consistent with past infections. These birds were from a captive group of about 200 birds to be used for breeding and reproduction research. A small sample of recently caught wild birds was serologically negative for chlamydial antibody activity. |
