Incidence of Vibrio parahaemolyticus Bacteriophages and Other Vibrio Bacteriophages in Marine Samples †
Vibrio bacteriophages were isolated by enrichment from 177 of 643 samples of marine molluscan shellfish, crustaceans, seawater, and sediments. The predominant bacteriophage types isolated were specific for some strains of Vibrio parahaemolyticus. A high frequency of phage isolations was also observe...

Vibrio bacteriophages were isolated by enrichment from 177 of 643 samples of marine molluscan shellfish, crustaceans, seawater, and sediments. The predominant bacteriophage types isolated were specific for some strains of Vibrio parahaemolyticus. A high frequency of phage isolations was also observed with strains of agar-digesting vibrios (21 of 56) and psychrophilic vibrios (14 of 72) that were originally isolated from non-shellfish growing areas. No bacteriophages were isolated against V. alginolyticus and only rarely for V. anguillarum even though these were the two most abundant species found in near-shore environments. No V. cholerae phages were isolated. It was also determined from quantitative studies on the Pacific oyster (Crassostrea gigas) obtained from two environments in Washington and Oregon that the titers of V. parahaemolyticus bacteriophages increased with increasing seasonal water temperatures and that this was proportional to the increase in numbers of mesophilic vibrios and not with the incidence of V. parahaemolyticus. Titers of V. parahaemolyticus bacteriophages occasionally exceeded 106 per g of oyster during the summer months. Specific V. parahaemolyticus bacteriophages were also isolated from market seafoods and other marine samples that originated in cold environments where no mesophilic vibrios are expected to be found. The possibility that V. parahaemolyticus bacteriophages originate from Vibrio spp. other than V. parahaemolyticus and the role of these bacteriophages in the ecology of marine vibrios are discussed. |
