Description of a Novel Symbiotic Bacterium from the Brittle Star, Amphipholis squamata

Michael P Lesser et al. Appl Environ Microbiol. 1990 Aug.

Abstract

A gram-negative, marine, facultatively anaerobic bacterial isolate designated strain AS-1 was isolated from the subcuticular space of the brittle star, Amphipholis squamata. Its sensitivity to O/129 and novobiocin, overall morphology, and biochemical characteristics and the moles percent guanine-plus-cytosine composition of its DNA (42.9 to 44.4) suggest that this isolate should be placed in the genus Vibrio. Strain AS-1 was not isolated from ambient seawater and is distinct from described Vibrio species. This symbiotic bacterium may assist its host as one of several mechanisms of nutrient acquisition during the brooding of developing embryos.
