Pathogen Characteristics

Top of page

M. synoviae is small with a genome size of 900 kbp (Herrmann, 1992), is pleomorphic, lacks a cell wall and has a low G+C ratio (34.2 mol%). M. synoviae is morphologically and biochemically very similar to M. gallisepticum. M. synoviae ferments glucose but does not hydrolyse arginine, nor does it possess phosphatase activity. However M. synoviae can be distinguished biochemically from M. gallisepticum by the former's inability to reduce tetrazolium salts aerobically. Some isolates of M. synoviae are reported to produce a film, although this is not a consistent feature.

M. synoviae and M. gallisepticum cause remarkedly similar clinical diseases in birds; a certain degree of serological cross reactivity has also been reported, especially in the rapid slide agglutination and ELISA tests (Avakian et al., 1988). Whilst the two mycoplasmas have similar colony sizes (0.1-2 mm), M. gallisepticum colonies often have no centres in early passage.
