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% NaCl than in filtered water without autoclaving. The lack of some essential nutrients, which may be degraded by autoclaving, might explain these results.
利用活菌计数法研究了空肠弯曲菌和大肠杆菌在湖水中的存活情况。在所有研究的测试条件下，大肠杆菌的存活情况均优于空肠弯曲菌。在过滤后的水中，这两种菌的存活情况均优于未处理的水。这表明捕食和/或对营养物质的竞争会影响这两种菌在水生环境中的存活。与未高压灭菌的过滤水相比，空肠弯曲菌在经过过滤的高压灭菌水中以及在0.9%氯化钠溶液中的存活情况较差。某些可能因高压灭菌而降解的必需营养物质的缺乏，或许可以解释这些结果。
