Two previously unreported Vibrio species have been isolated from three Brown Sharks (Carcharhinus plumbeus) which had recently arrived at the National Aquarium at Baltimore.  Clinical and necropsy results will be discussed in a separate presentation.  Though biochemically, these two species resembled other Vibrio species, particularly V. damsella and V. alginolyticus. Their % G + C values were significantly different.

This paper will present methods of isolation of initial cultures, transport, and isolation of pure cultures as well as biochemical data on each of the isolated species.  It is the collective opinion of all involved that these organisms are significant pathogens of Elasmobranchs.
