PG - 253-9 AB - Three strains of Mycoplasma synoviae (MS) (Olson-WVU 1853, reported in 1956; and Massachusetts 9895 and 5044, respectively isolated in 1957 and 1972) were used for experimental inoculation of chickens to evaluate the various mycoplasma serologic tests. The MS plate agglutination and hemagglutination-inhibition (HI) tests were highly sensitive for detection of infection; reactions persisted for test periods extending to 63 weeks. Correlation between MS HI-tube and micro methods was good. HI titers were highest in sera from birds inoculated with strain 9895. All three strains produced cross-reactions with M. Gallisepticum (MG) plate antigens, which were detectable for 2 to 12 weeks following MS inoculation; strain 5044 produced the lowest percentage of cross-reactions. MG HI titers of 16 were observed occasionally in sera from all three group inoculated with strain 1853. It appears from these limited serologic studies in chickens that there may be antigenic differences among the three MS strains.
