Comparative efficacy of serodiagnostic procedures on Chlamydia psittaci infections among livestock

Indirect microimmunofluorescence test on 184 morbid specimens for the detection of C. psittaci was adjudged to be superior than the conventional staining of impression smears with Giemsa and Gimenez stains and isolation in developing chicken embryos. The dot-ELISA was employed for the confirmation of 172 isolates of C. psittaci vis-a-vis indirect microimmunofluorescence and the efficacy of both the tests was observed to be equal. The 3 sero-diagnostic tests, viz. complement fixation (CFT), agar-gel precipitation (AGPT) and elementary body slide agglutination (SAT) were compared on 910 serum samples and it was concluded that the SAT can be performed for serodiagnosis of chlamydiosis in sheep, goats, poultry, wild birds and pigs.
