Chlamydiosis in captive raptors.
Chlamydia psittaci was isolated from four red-tailed hawks (Buteo jamaicensis) that died suddenly and from seven birds that survived at a raptor rehabilitation center in California in 1983. One hundred captive raptors representing 14 species in five families were subsequently tested serologically and by direct cloacal culture. C. psittaci was isolated from seven clinically normal birds. Forty-four percent of the raptors were considered positive using an enzyme-linked immunosorbent assay (ELISA), and 19% were suspects. The ELISA was repeated on 54 raptors in 1986. Forty-one percent of the birds were considered positive, and 35% were suspect, indicating that C. psittaci is endemic in the population.
