The bacterial flora of the gut contents and environment of larval lampreys
*Subscription may be required
The microbial flora of the contents of the intestine of larval lampreys, as well as of the water and substrate in the ammocoetes' habitat, have been cultured on Trypticase Soy Agar. The bacteria have been separated into taxonomic groups, using the scheme of Cowan and Steele (1974) and the API 20E system. The microbial flora of the gut contents of larval lampreys closely parallels that found in the environment in which the ammocoetes live. Bacillus, Aeromonas and Aeromonas-like organisms were by far the most abundant bacteria identified, followed by Pseudomonas and members of the Enterobacteriaceae. The only anaerobic components of the bacterial flora in the gut contents and the environment were Clostridium and a relatively uncommon and unidentified Gram-negative organism. Estimates of abundance of the microflora indicated that the concentration of bacteria was much greater in both the gut contents and the substrate than in the water overlying the animals' burrow.
