Gram-negative diplococci, 0.6-1.0 μm. Division in two planes at right angles to each
other and tetrad formation may be observed. Non-motile.
The colonies are conical, opaque, and often friable. The colony size in 48 h is similar
to, or slightly smaller than, that of M. catarrhalis. Nonhemolytic. Aerobic. Optimum
growth temperature 37 ºC. Can grow at 42 ºC. No growth on MacConkey agar or in
minimal medium containing ammonium and acetate.
Isolated from the mouth of healthy rabbits.

Positive results for alkaline phosphatase, acid phosphatase (weak reaction),
catalase, esterase and oxidase.
Negative results for DN-ase, gelatin liquefaction, indole production, nitrate reduction,
phenylalanine deamination, Tween 80 hydrolysis and urease. Acid is not produced
from sugars.
