Abstract

We report a study to determine the presence of Listeria species in surface waters. One hundred ml volumes of 30 water samples taken from 21 different sites were analysed. Most of the samples examined were from ponds and lakes. Listeria species were isolated on eight (27%) occasions, six of these isolates were L. seeligeri, one was L. innocua and one L. welshimeri. Although not statistically significant, coliform and Escherichia coli counts were higher in waters that were positive than were negative for Listeria spp. It is suggested that the low isolation rate of listeria in this study reflects the fact that most waters examined did not receive sewage outfalls. Water sports activities are unlikely to be a risk factor for listeriosis.

摘要

我们报告了一项旨在确定地表水中李斯特菌属存在情况的研究。对从21个不同地点采集的30份水样各100毫升进行了分析。所检测的大多数样本来自池塘和湖泊。在8次(27%)检测中分离出了李斯特菌属,其中6株分离菌为斯氏李斯特菌,1株为无害李斯特菌,1株为威尔士李斯特菌。虽然无统计学意义,但李斯特菌属检测呈阳性的水体中大肠菌群和大肠杆菌的数量高于检测呈阴性的水体。本研究中李斯特菌的低分离率表明,大多数检测水体未受到污水排放影响。水上体育活动不太可能是李斯特菌病的风险因素。
