The strains, all isolated from pathological processes in animals, were divisible into the two biotypes of Fievez (1963) were recognized, differing in colony morphology, cell morphology, degree of haemolysis, growth in broth, and haemagglutination. The following characters were shared by all strains: Gram-negative, anaerobic, nonsporeforming, immotile rods, producing acid from fructose, glucose, mannose, maltose, and (variably) from galactose, but not from arabinose, xylose, lactose, saccharose, cellobiose, melezitose, adonitole, sorbitole, mannitole, and salicine. Terminal pH in glucose medium was 5.77 plus or minus 0.17. Growth was not inhibited by 0.008% brilliant green, but was partially inhibited by 10% ox bile. Indole was produced. Nitrate was not reduced. A lecithinase was present. Proteolytic properties were present. Threonine was deaminated. The fatty acids: acetic, propionic, and butyric acid were produced in medium both with and without glucose.
