Recent publications support the health significance of injured microorganisms. These reports show that enteropathogenic bacteria are less susceptible than pollution indicators to injuries under conditions similar to those in drinking waters, and that injured pathogens retain the potential for virulence. This experimental investigation has been led to point out the effects of some antimicrobials, as well as the responsibility of environmental pollutants, in determining sublethal injuries to microbial cells. The study has been carried out by the application of a new analytical method, based on the definition of the kinetics of growth which characterize bacterial strains taken into account. Resuscitation of stressed or injured microorganisms is enhanced by inoculating bacterial cultures in a liquid, noninhibitory medium.
