Abstract

The mortality of a clinical Helicobacter pylori strain was assessed by inoculating it in untreated well water, filtered well water, and autoclaved well water. Two different temperatures (5 and 25°C) were used during the experimental period. Because Escherichia coli is commonly used as indicator of faecal pollution of water, we compared the survival of H. pylori using E. coli as indicator of its persistence. H. pylori was not culturable 48 h after inoculation, whereas the population of E. coli, monitored at the same temperature, decreased slowly, especially in filtered water. In untreated water, both H. pylori and E. coli survived less well than in filtered and autoclaved water. In general the survival of H. priori and E. coli was better in filtered water than in autoclaved water and the ability of H. priori to survive several days in water at 5°C is reported, supporting the observation that H. pylori survives better at 5°C than at higher temperature. This suggests a possible faecal-oral transmission of H. priori in the presence of a contaminated water.
