Mass Cultures

The heterotrophic bacteria present in 15 mass cultures of six different genera of algae used for feeding larvae of the Atlantic oyster, Crassostrea virginica, and the hard clam, Mercenaria mercenaria, were isolated, identified, and their physiology studied. Of the 120 isolates obtained, 118 (98.3%) were asporogenous, gram-negative rods — types commonly found in marine waters. The majority of the isolates, 98 (81.6%), belonged to the genus Pseudomonas.

Quality Of Water

Shellfish (Crassostrea virginica and Mercenaria mercenaria) and shellfish-raising waters from a variety of Long Island and New Jersey marine embayments were examined for the presence of human enteroviruses. Little difference in virological quality was noted between areas designated as being open or closed to shellfishing. Viral isolations could not be correlated with coliform counts from identical samples, indicating the need to re-evaluate the use of bacterial standards as indices of the overall sanitary quality of water and shellfish.
