RESUMO

Survival of chlorine-injured and noninjured subpopulations of enterotoxigenic Escherichia coli was compared in KH2PO4-buffered water and chlorine-neutralized tap water. Injured cells were no less persistent than noninjured cells and did not exhibit limited survival as a consequence of chlorine injury. At high inoculum densities, some injured cells were able to repair, apparently owing to the accumulation of materials arising from the chlorination procedure.
