“…The samples were close to a point source of domestic pollution, and this may be a factor in persistence. The general survival of C. albicans in seawater (1,16,32,33) has not been quantitated adequately.…”

Candida parapsilosis, C. tropicalis, and Torulopsis glabrata were the human-associated yeasts most frequently isolated from quahogs, oysters, and mussels collected from four estuarine areas along the northern shore of Long Island Sound. Some inconsistency and seasonal variation in the occurrence of these and other yeast species were noted. In particular, C. albicans densities were greatest during colder months in the more heavily polluted waters. A total of 347 yeasts were isolated and cultured at 37°C and, of these, 219 or 62% were human-associated forms. Generally, these yeasts in the animals sampled reflected the overall pollution status of the estuary from which they were taken. This study represents a clear demonstration of potentially pathogenic yeasts in a valuable marine resource. The occurrence of human pathogenic microorganisms in native populations of bivalve molluscs is well-documented (4-6, 9, 14, 20, 25, 27, 35, 37-39, 42). In addition, a variety of shellfish species have been shown to accumulate and eliminate coliforms (10, 11, 24), other bacteria (26), and virtlses (15, 30) under experimental conditions. These reports, in addition to outbreaks of viral hepatitis traced to the consumption of raw shellfish (7), indicate that recreationally and economically valuable bivalve molluscs represent a potential health hazard in some areas. Considering the filtering capacities of molluscan shellfish for particles in the yeast cell size range (23) and the known presence and survival of human pathogenic yeasts in coastal
