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

Genome Structure


A. delphinicola is circular, it contains 1 chromosome.


There is 1837244 nucleotides, 1626 protein genes and 85 RNA genes found.

Cell Structure, Metabolism and Life Cycle


It's known to be a microaerophile, and is mesophilic ideally growing from 37-44 Celsius.

It is facultatively anaerobic but CO2 is required for the growth, while blood can also enhance it's growth.

Ecology and Pathogenesis

A. Delphincola is found in marine environments and lives in the tissues of cetaceans, mainly in the uterus, cervix, lungs, and intestines.

The Genus Actinobacillus itself is known to be susceptible to the beta-lactam family of antibiotics, including chloramphenicol, aminoglycosides, tetracyclines, and antibacterial chemotherapeutics.
