目的:了解东阳市鼠类中携带耶尔森菌的类型,不同鼠种的带菌率及不同季节的消长情况。方法:一年分四季采样,采用冷增菌分离方法从鼠类回盲部内容物中分离耶尔森菌。结果:从2007年-2009年之间共采集725份鼠类肠道内容物标本,分离到小肠结肠炎耶尔森菌40株,假结核耶尔森菌12株,中间/弗氏型耶尔森菌2株,克氏耶尔森菌1株。按季节分布以春季检出率最高。结论:东阳市鼠类中人畜共患疾病的耶尔森菌均有携带,尤其小肠结肠炎耶尔森菌的检出率最高5.52%,其次是为假结核耶尔森菌1.79%;一年中以温度最低的春季检出率最高,符合耶尔森菌为嗜冷菌。
OBJECTIVE: To understand the types of Yersinia carrying rodents in Dongyang City, the carrier rates of different rat species and the growth and decline in different seasons. Methods: One year and four seasons were sampled, Yersinia was isolated from the contents of the rodent ileocecal part by the method of cold enrichment and separation. Results: A total of 725 specimens of intestinal contents were collected from 2007 to 2009, 40 strains of Yersinia enterocolitica, 12 strains of Yersinia pseudotuberculosis were isolated, 2 strains of Sen bacteria, 1 strain of Yersinia pestis. According to the distribution of the highest detection rate in spring. Conclusion: The yersinia zoonotic disease of rodents in Dongyang City are all carried, especially the detection rate of Yersinia enterocolitica is 5.52%, followed by that of Yersinia pseudotuberculosis 1.79%; one year In the lowest temperature in the spring the highest detection rate, in line with Yersinia psychrophilic bacteria.
