Effects of temperature and salinity on the survival of Vibrio vulnificus in seawater and shellfish
Article Abstract:
Sterilized seawater used to study the influence of temperature and salinity on the survival of Vibrio vulnificus showed that between 13 and 22 degrees centigrade, Vibro vulnificus population increased during the 6-day incubation. At restrictive temperatures, their numbers diminished by 90%. At salinity between 5 and 25 ppt and at 14 degrees centigrade, Vibrio vulnificus population increased or remained unaffected after 6 days of incubation. Biological and physiochemical factors are pivotal to the existence of Vibrio vulnificus in the environment, and temperature is critical to controlling its multiplication in oyster shellstock.

Multiple Vibrio vulnificus strains in oysters as demonstrated by clamped homogeneous electric field gel electrophoresis
Article Abstract:
Analysis of genomic DNA of 118 Vibrio vulnificus strains by a computer program and clamped homogeneous electric field gel electrophoresis reveals the existence of significant genomic diversity among V. vulnificus organisms in individual oysters. The heterogeneous nature of strains is revealed by principal component analysis. Experimental data support the two hypothesis associated with human V. vulnificus infections.

rpoS regulation of acid, heat, and salt tolerance in Escherichia coli O157:H7
Article Abstract:
An rpoS mutant of Escherichia coli O157:H7 ATCC 43895 is generated to determine the role of rpoS-regulated proteins in acid, heat and salt tolerance of the bacterium. Results suggest that existence of a stationary phase in E. coli. This phase degrades the acid, heat and salt tolerance of E. coli. The mutant does not possess this property.
