Historical synonyms: Corresponds to Frederiksen’s third taxon of M. haemolytica (Frederiksen 1973), classified as P. haemolytica
biogrups 3 and 5 by Bisgaard and Mutters, 1986 and reclassified as M. haemolytica biogroups 3A-H bu Angen et al (1973). Also
includes NPG and meso-inositol positive strains of M. haemolytica biogroup 9 (Bisgaard and Mutters, 1986).

Gram-negative, nonmotile, small rods.
Regular colonies, smooth, and graysh on blood agar; 1-2 mm in diameter,
beta-hemolytic on bovine blood agar.
Strains are V-factor independent and X-factor independent. Growth on MacConkey is
variable. Mesophile and facultative anaerobe.

Isolated from sheep and cattle; probably represents part of the resident microflora in the upper respiratory tract . Also isolated from
ovine lung.
ovine lung.
Normally is not associated with disease. Serotype A11 produces a leucotoxin.
