Synonym:
Neisseria caviae Pelczar 1953.
Possible synonym:
Neisseria flava Bergey et al. 1923 (99.9% similarity with M. caviae by 16S RNA gene sequence).
Gram-negative diplo-cocci, 0.6-1.0 μm. Division in two planes at right angles to each
other and tetrad formation may be observed. Nonmotile.
Colonies are low, conical, approximately 2.5 mm in diameter after 48 h incubation,
semiopaque and have a butyrous consistency. Weak hemolysis may be observed,  
resembling
M. ovis. Aerobic. Optimum growth temperature 37 ºC. Can grow at 22 ºC,
but not at 42 ºC. Growth occurs on trypticase soy agar. No growth on MacConkey agar.
Isolated from the pharyngeal region of guinea pigs.

Positive results for alkaline phosphatase, catalase, esterase, oxidase & nitrate
reduction.
