Phylum Proteobacteria, Class Gammaproteobacteria, Order Pasteurellales, Family Pasteurellaceae, Genus Actinobacillus,
Actinobacillus scotiae Foster, Ross, Patterson, Hutson and Collins 1998.
Gram-negative, pleomorphic rods, nonmotile, nonsporulated.
Colonies are 0.5 mm. in diameter after 24 h incubation on Columbia agar with 5%
citrated sheep blood and incubated at 37 ºC in an atmosphere containing 10% added
CO2. Weakly hemolytic.
Facultatively anaerobic. Added CO2 is required for growth. Blood or serum enhances
growth. No growth on MacConkey agar. X and V factors are not required. Growth
occurs at 25 ºC, but not at 42 ºC.
Isolated from porpoises (Phocoena phocoena).
One strain was recovered from the brain, lung, spleen, liver, mesenteric lymph node, blood, and small intestine of one animal that
died of septicemia.
