Abstract

The survival and replication of male-specific bacteriophages in hard-shelled clams (Mercenaria mercenaria) and their homogenates were examined to further assess their potential utility as indicator organisms. Trials were conducted in the presence and absence of a suitable bacterial host, Escherichia coli HS[pFamp]R. Results of this study demonstrated that male-specific bacteriophages were unable to replicate in hard-shelled clams, with or without added host cells. In addition, the densities of these bacteriophages were stable for up to 7 days in shellfish held at ambient seawater temperatures (less than 25 degrees C). Evidence of replication, although not observed in live shellfish, was found to occur in temperature-abused shellfish homogenates and supernatants, but only when a suitable bacterial host was present.
