LOW PATHOGENIC POTENTIAL IN HETEROTROPHIC BACTERIA FROM POTABLE WATER
Stelma Jr., G N., J W. Messer, D J. Lye, AND B G. Smith. LOW PATHOGENIC POTENTIAL IN HETEROTROPHIC BACTERIA FROM POTABLE WATER. Presented at Annual Meeting of the Water Quality Association, Orlando, FL, March 29, 2001.
Develop data for use in assessing the efficacy of the in vitro virulence tests in predicting pathogenicity of heterotrophic bacteria and in assessing risk of infection by opportunistic pathogens in potable water and to attempt to identify possible opportunistic pathogens among the heterotrophic bacteria that occur in drinking water, while determining the influence of type of source water or treatment technology on the occurrence of opportunistic pathogens.
Forty-five isolates of HPC bacteria, most of which express virulence-related characteristics are being tested for pathogenicity in immunocompromised mice. All forty-five were negative for facultative intracellular pathogenicity. All twenty-three isolates tested thus far were also negative for extracellular pathogenicity.
