Field evaluation of a microtitration complement-fixation test for diagnosis of Mycoplasma gallisepticum in chickens.
Results of a direct microtitration complement-fixation (CF) test were compared with hemagglutination-inhibition (HI) test results in diagnosing Mycoplasma gallisepticum (MG) infection of chickens in the field. Of 16 flocks negative for MG by the HI test, eight were CF-positive. Of nine flocks that were HI-positive for MG, three were CF-negative. It was concluded that the CF test is not effective in diagnosing MG infection of chickens in the field.
