Serologic studies with Mycoplasma synoviae in experimentally inoculated chickens. 1976

O M Weinack, and G H Snoeyenbos

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.

UI	MeSH Term	Description	Entries
D009174	Mycoplasma	A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D003429	Cross Reactions	Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.	Cross Reaction,Reaction, Cross,Reactions, Cross
D006385	Hemagglutination Inhibition Tests	Serologic tests in which a known quantity of antigen is added to the serum prior to the addition of a red cell suspension. Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of hemagglutination.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
