Actinobacillus delphinicola

Description and Significance


This is a species of bacteria from the family Pasteurellaceae. Actinobacillus delphinicola is a gram-negative, rod-shaped bacterium. It was reported for the first time in 1993 isolated from the lungs of a harbour porpoise in the North Atlantic Ocean. It is pleomorphic, catalase negative and non-motile and known to be non-hemolytic or weakly hemolytic. This strain is known as M906/93T (=NCTC 12870 =ATCC 700179 =DSM 11374 =CIP 106129). This organism is also
