为进一步掌握鼠疫宿主动物的种群组成、变动及其染带关系,东阳市卫生防疫站于1998年11月5日对鼠类及媒介蚤类进行了检测.用笼日法捕捉活鼠,梳检鼠体蚤,计算染蚤率和蚤指数,采集鼠血及肝、脾各一小块,用IHA法进行血清学检测及病原学培养.检测结果,捕活鼠2110只,经鉴定为2目4科8属13种,褐家鼠为室内优势种(68.44%),黑腹绒鼠和黑线姬鼠为野外优势种(80.89%),雌雄性别比为1:1.01,染蚤率4.88%,总蚤指数0.075,不等单蚤和缓慢细蚤为优势种(83.33%),白腹巨鼠带蚤率最高(25%),其次为罗赛鼠(l.38%)、黄胸鼠(11.63%),未发现鼠疫主要传播媒介印鼠客蚤,鼠疫菌培养及鼠血清IHA法检测均呈阴性.说明我市鼠疫疫源地仍处于静息期,但我们决不能放松警惕,要加强常年监测,大力开展宣传教育,采取灭鼠、灭蚤等综合性防制措施,严防鼠疫死灰复燃.
In order to further understand the population composition, variation and the relationship of the zoonotic host animals, Dongyang Sanitary and Epidemic Prevention Station tested the rodents and the media fleas on November 5, Flea flea, calculate flea infection rate and flea index, collecting rat blood and liver, spleen each a small piece, using IHA method for serological testing and etiological culture test results, catching 2110 mice, identified as 2 head 4 families, 8 genera and 13 species. Rattus norvegicus was the indoor predominant species (68.44%), the dominant species (80.89%) were black pollinator and Apodemus agrarius, the male-male ratio was 1: 1.01, the rate of stained flea was 4.88% , Total flea index 0.075, the dominant species (83.33%) were single flea and slow flea, the highest rate of flea flea (25%), the second was flea (1.38%), (11.63%). No fleas were found in the main media of plague, but Yarrowie was also negative for culture of Yersinia pestis and IHA method, indicating that the plague foci in our city are still at rest. However, we should never relax our vigilance Strengthen perennial monitoring, vigorously carry out publicity and education, to take anti-rat, fleas and other comprehensive prevention and control measures to prevent the resurgence of the plague.
