Serological investigation of horse sera for antibodies against mycoplasmas and acholeplasmas.
Sera from horses with respiratory disease (RD) have been investigated using the complement fixation test, indirect hemagglutination test, enzyme immune assay, and the metabolic inhibition test, and sera from mares after abortion, using the complement fixation test, indirect hemagglutination test and enzyme immune assay, for antibodies against Mycoplasma equirhinis, M subdolum, M. equigenitalium, M. pulmonis, M. felis, Acholeplasma laidlawii, A. hippikon and A. equifetale. Antibodies were found against all mycoplasma and acholeplasma species tested, more often against acholeplasmas. The antibody pattern was quite similar for horses with RD and for mares after abortion. The results of the four serological tests performed showed only a limited correlation and the percentage of sera with antibodies detected by the four tests used differed widely.
