title: Direct complement fixation and isolation attempts for detecting Chlamydia psittaci infection of psittacine birds.
abstract: Serum and fecal specimens from 147 birds were tested for Chlamydia psittaci. Isolation rates ranged from 3.4% of 88 birds that had titers less than 8, to 50% of six birds that had titers greater than or equal to 128. Testing of 44 paired sera revealed a significant titer increase in 5 pairs, a significant titer decrease in 8 pairs, and a stable titer in 31 pairs. The examination of both feces and serum is recommended for determining Chlamydia psittaci infections in individual live psittacine birds.
