^aIsolates from individual samples were combined to form a composite based upon sample origin. IM, intestinal mass; B, bone-associated sample; S, sediment; CA, clastic anchor. Isolates are not reported where the MIDI similarity indices fall below the level of acceptable identification (<0.5). 

^bInitial identifications of isolates were determined by FAME analyses. Identifications of facultatively anaerobic gram-negative rods were confirmed by API-20E profiles.
