摘要: 目的:了解深圳市肾综合征出血热(HFRS)疫源地的现状。方法:在全市6个行政区设11个点布笼捕鼠,以整群抽样方法调查鼠类种群构成,间接免疫荧光法检验鼠血清汉坦病毒(HV)抗体,直接免疫荧光法检验鼠肺HV抗原。结果:共获鼠形动物625只,捕获率11.07%,其中褐家鼠368只,占58.88%。鼠血清HV抗体阳性率为7.17%(36/502),GMT为54.45,鼠肺抗原阳性率为0.81%(5/619),阳性鼠肺及血清全部为褐家鼠。结论:深圳市存在家鼠型HFRS疫源地,广泛分布在全市6个行政区的11个调查点,褐家鼠是主要宿主动物。

Abstract: Objective:To observe the current situation of the HFRS Epidemic Foci in Shenzhen.Methods:11 places were selected to lay cages for capturing mice;the population structure of rat was investigated through cluster sampling,the anti-Hantavirus antibody was detected by Indirect Immunofluorescent Assay and Hantavirus antigen was detected by Direct Immunofluorescent Assay.Results:625 mouse-like animals were captured and the capture rate was 11.07%,in which there were 368 Rattus norvegicus(58.88%),and the serum positive rate of anti-Hantavirus antibody was 7.17%(36/502),GMT was 54.45,the antigen positive rate of mouse lung was 0.81%(5/619),and all the positive serum and lung were from Rattus norvegicus.Conclusions:There are rattus-related HFRS Epidemic Foci in Shenzhen distributed in all the 6 districts of the city and 11 investigated places,and the Rattus norvegicus are the major host animals.
