肾综合征出血热(HFRS)是一种自然疫源性疾病,四川南充是高发区之一。为了探索肾综合征出血热宿主动物生态,我们于1987年6月至1988年5月在南充进行了研究。本研究共捕鼠7种1677只,其总密度为12.15％(1677/13798)。其中野外捕获781只,密度为15.62％;室外362只,密度为9.95％;室内534只,密度为10.35％。野外以四川短尾鼩和黑线姬鼠为优势种,分别占66.91％和26.50％;室内以褐家鼠为优势种占77.15％。用间接免疫荧光技术检查1477只,有5种鼠携带HFRS病毒,42只鼠带毒,带毒率为2.84％。以黑线姬鼠带毒率为最高6.76％;次为褐家鼠2.42％;四川短尾鼩为1.76％。由此可见该流行区主要宿主动物为黑线姬鼠,褐家鼠和四川短尾鼩。这些鼠种的带毒在自然界中起到储存病原体的重要作用。因此,控制疫区的鼠害对减弱HFRS病毒的传播极为重要。
Hemorrhagic fever with renal syndrome (HFRS) is a natural foci disease, Nanchong, Sichuan Province is one of the high incidence areas. In order to explore the host animal ecotypes of hemorrhagic fever with renal syndrome, we conducted a study in Nanchong from June 1987 to May 1988. In this study, a total of 1677 mice were caught, with a total density of 12.15% (1677/13798). Among them, 781 were captured wildly, with a density of 15.62%; 362 were outdoor with a density of 9.95%; and 534 were indoor with a density of 10.35%. In the wild, Apodemus agrarius and Apodemus agrarius were the dominant species, accounting for 66.91% and 26.50% respectively; indoors, the dominant species was Rattus norvegicus, accounting for 77.15%. 1477 were detected by indirect immunofluorescence technique. Five kinds of mice carried HFRS virus and 42 rats were poisoned with a rate of 2.84%. The black-poisoned Apodemus agrarius was the highest with 6.76%; the second was 2.42% of the brown rat; and the Short-tailed macaque was 1.76%. Thus it can be seen that the main host animals in this endemic area are Apodemus agrarius, Rattus norvegicus and Siberian horsetail. The virulence of these murine species plays an important role in the storage of pathogens in nature. Therefore, the control of rodent pests in affected areas to reduce the spread of HFRS virus is extremely important.
