Hemagglutination-inhibition versus serum plate agglutination in detecting Mycoplasma gallisepticum in broiler flocks.
Sera from 43,040 broilers in 36 flocks were tested for antibodies to Mycoplasma gallisepticum by serum plate agglutination (SPA) and hemagglutination-inhibition (HI) tests. The importance of testing SPA-negative samples for HI antibodies was demonstrated.
