The number of cases of chlamydiosis in psittacine birds from various areas of the USA are reported (1978-1983). Serotesting of 3485 birds by direct complement-fixation method detected antibody titres of: 8 in 340 (9.8%); 16 in 333 (9.6%); 32 in 309 (8.9%); 64 in 263 (7.5%); 128 in 110 (3.1%); and 256 in 76 (2.2%). 476 (13.7%) birds were considered to have active Chlamydia psittaci infections.
