近年来,弯曲杆菌作为细菌性肠炎的一种病原体,引起了人们的重视。这种细菌通过受污染的水和食物传播,已在人群中引起几次大爆发。作者对弯曲杆菌在地表水中是否存在季节性变化以及与指示菌和环境中各种物理因素之间是否存在着相互关系进行了研究。本文用三管最可能数法计数水体中弯曲杆菌,用滤膜法计数总大肠菌群、粪大肠菌群和粪链球菌。从美国华盛顿州中部的各种天然水体(湖泊、水塘、河流和山中小溪)采集水样,结果发现,空肠弯曲杆菌和大肠弯曲杆菌广泛地存在于这些水体中。在所有采样点中,弯曲杆菌的检出率在秋天(55%)和冬天(39%)较
In recent years, Campylobacter bacteria as a bacterial enteritis, has attracted people’s attention. This bacterium, which spreads through contaminated water and food, has caused several major outbreaks in the population. The authors investigated whether Campylobacter exists seasonal variations in surface water and whether there is a correlation between indicator bacteria and various physical factors in the environment. In this paper, the most probable number of three pipe counting bacteria Campylobacter, with the total count of coliform bacteria, fecal coliform and Streptococcus faecalis. Water samples were collected from a variety of natural waters (lakes, ponds, rivers, and mountain streams) in central Washington State and results showed that Campylobacter jejuni and Campylobacter coli are widely present in these waters. The prevalence of Campylobacter in all sampling sites was lower in autumn (55%) and in winter (39%) than in winter
