L.K. KORHONEN AND P.J. MARTIKAINEN. 1991. The survival of Campylobacter jejuni and Escherichia coli in lake water was studied using viable counts. Escherichia coli survived better than C. jejuni in all the test conditions studied. Both the species survived better in filtered than in untreated water. This suggests that predation and/or competition for nutrients affect the survival of both the species in an aquatic environment. Campylobacter jejuni survived less well in filtered autoclaved water and in 0.9% NaC1 than in filtered water without autoclaving. The lack of some essential nutrients, which may be degraded by autoclaving, might explain these results.
