Distribution of Vibrio vulnificus in the Chesapeake Bay
Article Abstract:
The pathogenic bacteria Vibrio vulnificus is one of the main bacterial species present in the water and oysters of the Chesapeake Bay, especially during the warmer months. The bacterial concentration decreases with an increase in water salinity and is dependent on the depth from which the sample is collected. The bacteria are present in oysters collected from water at 7.6 degrees centrigrade. An oligonucleotide DNA probe specific for V. vulnificus is used to identify the bacteria in water samples collected between Apr. 1991 to Dec. 1992.

Distribution of viruses in the Chesapeake Bay
Article Abstract:
The viral particles present in Chesapeake Bay water samples were monitored in relation to sample depth, degree of stratification and season. Morphological observations showed that the predominant viral types were bacteriophages. Virus counts showed that the viral populations peaked during August and October, during which time the bacterial counts were lowest. The results imply that the presence of viruses in natural waters may be an important factor influencing bacterial populations and gene transfer within the same locations.

Iasolation and diversity of actinomycetes in the Chesapeake Bay
Article Abstract:
Approaches for the isolation of actinomycetes from marine and estuarine environments were studied. Actinomycetes were derived from Chesapeake Bay sediment samples and were subjected to antimicrobial activity profiles, cell wall analysis and DNA hybridization studies. The suitability of the Chesapeake Bay for the isolation and the determination of diversity among actinomycetes was established.
