Membrane filter procedure for enumeration of Vibrio parahaemolyticus.
Watkins, W D, Thomas, C D, Cabelli, V J
A membrane filtration procedure has been developed for the enumeration of Vibrio parahaemolyticus in marine waters. Background microbial growth on the primary medium was decreased through the use of...
Direct plating procedure for enumerating Vibrio vulnificus in oysters (Crassostrea virginica).
Miceli, G A, Watkins, W D, Rippey, S R
A procedure for enumerating and identifying Vibrio vulnificus in oysters was developed and evaluated. This method consists of growth on a direct plating medium (VVE medium) for isolating the organism...
Seasonal effects on accumulation of microbial indicator organisms by Mercenaria mercenaria.
Burkhardt, W, Watkins, W D, Rippey, S R
The ability of hard-shelled clams (Mercenaria mercenaria) to accumulate fecal coliforms and other microorganisms (Escherichia coli, Clostridium perfringens, and male-specific bacteriophages) was...
Survival and replication of male-specific bacteriophages in molluscan shellfish.
Burkhardt, W, Watkins, W D, Rippey, S R
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...
Wright, A C, Miceli, G A, Landry, W L, Christy, J B, Watkins, W D, Morris, J G
An oligonucleotide DNA probe (VVAP) was constructed from a portion of the Vibrio vulnificus cytolysin gene (hylA) sequence and labeled with alkaline phosphatase covalently linked to the DNA. Control...
Novel compound for identifying Escherichia coli.
Watkins, W D, Rippey, S R, Clavet, C R, Kelley-Reitz, D J, Burkhardt, W
A new chromogenic compound, 5-bromo-4-chloro-3-indoxyl-beta-D-glucuronide, was found to be useful for the rapid, specific, differential identification of Escherichia coli in the sanitary analysis of...
Effect of fecal pollution on Vibrio parahaemolyticus densities in an estuarine environment.
Vibrio parahaemolyticus densities in the Narragansett Bay, R.I., estuary were found to significantly correlate with the level of fecal pollution in the water. Results of field investigations showed a...
