EVALUATION OF 2 COMMERCIAL ENZYME-LINKED-IMMUNOSORBENT-ASSAY KITS FORTHE DETECTION OF MYCOPLASMA-GALLISEPTICUM ANTIBODIES

Sensitivity and specificity of two commercial Mycoplasma gallisepticum (MG) enzyme-linked immunosorbent assay (ELISA) kits, rapid slide aggl utination (SA) and haemagglutination inhibition (HI) tests were compar ed using sera from specific pathogen free chickens, turkeys or ducks w hich had been inoculated with various avian mycoplasmas, bacteria or w ith a reovirus. Results show that sensitivity of SA was superior to EL ISA and HI tests in the ability to detect antibodies formed in early r esponse to MG infection. However, both ELISA kits and HI tests had a h igher degree of specificity.
