背景资料：很少有研究已经进行了沙门氏菌在啮齿动物的存在，栖息在湿货市场，在东南亚的日常生活中发挥着重要作用。啮齿动物作为沙门氏菌携带者的研究结果差异很大，从不存在沙门氏菌到高流行率。以前的研究调查了农场、城市和野生地区等栖息地，这些地方的啮齿动物与人类的相互作用比湿货市场少。因此，潜在的作用，啮齿动物的水库和发射机沙门氏菌在湿markets.Methods：啮齿动物被困在8个传统的湿市场在泰国和确定的物种水平。结果：共检测了110只大鼠（褐家鼠和黄家鼠）。总体而言，沙门氏菌在大鼠中的流行率为49.10%，但在市场之间变化为0%至73.3%。鉴定出三种血清型：鼠伤寒沙门氏菌（30%）、沙门氏菌（30%）、沙门氏菌（30%）。Weltevreden（12.7%）和S. 4，[5]，12：i：-（6.4%）。结论：由于与人和食物的密切接触，湿货市场中的啮齿动物是沙门氏菌的潜在宿主。三个分离血清型中，S。4，[ 5]，12：i：-首次在啮齿类动物中报道，是泰国从人类分离的10种最常见的血清型之一。因此，应更多地关注啮齿动物作为沙门氏菌的潜在宿主。
Background: Few studies have been conducted on the presence of Salmonella in the rodents that inhabit the wet markets that play an important role in daily life in Southeast Asia. The results of studies of rodents as carriers of Salmonella vary greatly, ranging from an absence of Salmonella to high prevalences. Previous studies investigated habitats such as farms and urban and wild areas where there is less rodent-human interaction than in wet markets. Consequently, the potential role of rodents as reservoirs and transmitters of Salmonella in wet markets is of great interest.Methods: Rodents were trapped in eight traditional wet markets in Thailand and identified to species level. Subsequently, they were screened for Salmonella and isolates were serotyped.Results: A total of 110 rats (Rattus norvegicus and Rattus exulans) were examined. Overall, the prevalence of Salmonella in rats was 49.10%, but varied between 0% and 73.3% among markets. Three serovars were identified: Salmonella Typhimurium (30%), S. Weltevreden (12.7%), and S. 4,[5], 12: i:- (6.4%).Conclusions: Our results show that rodents in wet markets are a potential reservoir of Salmonella due to the close contact they have with humans and food. The three isolated serovars, of which serovar S. 4,[ 5], 12: i: -is reported for the first time in rodents, are among the 10 commonest serovars isolated from humans in Thailand. Thus, more attention should be paid to rodents as potential reservoirs of Salmonella.
