目的了解城镇、农田、农舍鼠类密度、种类、数量变化,及其携带肾综合征出血热(HFRS)病毒情况,为制定综合防制方案提供科学依据。方法采用夹夜法,每月均在1~15日期间布夹,每个监测点每次布鼠夹300夹以上,晚放晨收。将捕获的鼠类无菌解剖取肺进行冰冻切片,作FHFS病毒抗原检测。结果布鼠夹11 105个,捕获鼠类974只(8个品种),平均鼠密度为8.77%;对符合无菌要求取的823份鼠肺样本进行冰冻切片检测,有4只不同种类的鼠检出HFRS病毒抗原阳性,带毒率为0.49%;黑线姬鼠带毒率最高(2.78%),其次分别为小家鼠(1.92%)、褐家鼠(0.40%)和四川短尾鼩(0.21%)。黑线姬鼠的带毒率分别是小家鼠、褐家鼠、四川短尾鼩的1.40倍、6.95倍和13.24倍。结论城镇、农田、农舍的鼠类均带毒。因此,开展城镇、农田、农舍统一灭鼠十分必要。
Objective To understand the density, species and quantity of rodents in urban areas, farmlands and farmhouses, and to analyze the incidence of HFRS virus in rural areas and to provide a scientific basis for formulating a comprehensive prevention and control program. Methods The method of nocturnal night was used. Cloth clips were kept on the 1st to the 15th of every month. Each monitoring point was distributed over 300 clips at a time. The captured rat aseptic dissection lungs were frozen section for FHFS virus antigen detection. RESULTS: A total of 11 105 cloth rattrap mice were caught, 974 mice were captured (8 breeds) with an average rat density of 8.77%. 823 rat lung samples that meet the sterility test were frozen and sectioned and 4 different species of rats The positive rate of HFRSV was 0.49%; the highest rate was 2.78% in Apodemus agrarius, followed by 1.92% of mice, 0.40% of Rattus norvegicus, (0.21%). Apodemus black band poisoning rates were 1.20 times, 6.95 times and 13.24 times than that of Mus musculus, Rattus norvegicus, and Sichuan. Conclusions Town, farmland and farmhouse rats are poisonous. Therefore, to carry out the town, farmland, farmhouse unified rodent control is necessary.
