目的掌握宁德城澳港鼠形动物的分布及其携带体表寄生虫和病原体的情况,为病媒及其传染病的防制工作提供科学依据。方法采用鼠笼法,进行为期1年每月1次的调查,同时检测鼠形动物体表寄生虫和病原体。结果共捕获鼠形动物121只,年平均鼠形动物密度为3.36%;隶属2目2科2属5种,以褐家鼠为优势种,占83.47%。鼠形动物季节性明显,6月份鼠类密度最高,为10.33%;不同生境鼠形动物密度不全相同,办公区密度最高(6.25%)。检获螨、蜱各一种,鼠体染虫率及各鼠体表寄生虫平均指数均较低。汉坦病毒阳性率为13.33%,钩端螺旋体阳性率为1.43%。结论宁德城澳港鼠形动物密度未达到国家无鼠害港规定的鼠密度低于1%的要求;鼠形动物携带体表寄生虫率低,种类单一;汉坦病毒阳性率较高,应加强防控,防止相关传染病的发生。 Objective To understand the distribution of mouse-form animals and their introduction of surface parasites and pathogens in Ningde, Cheng’ao Harbor so as to provide a scientific basis for the prevention and control of vector diseases and their infectious diseases. Methods The squirrel-cage method was used to conduct the survey once a month for one year and detect the surface parasites and pathogens of the mouse-shaped animals at the same time. Results A total of 121 mouse-shaped animals were captured, with an annual average density of 3.36%. Five species belonged to 2 orders, 2 families and 2 genera, and dominant species were Rattus norvegicus, accounting for 83.47%. The rat was obviously seasonal. The highest density of rats was 10.33% in June. The density of mouse-shaped animals in different habitats was the same, and the density in office was the highest (6.25%). The seizures of mites and ticks showed a lower incidence of coccidia and the average index of parasites in each mouse. Hantavirus positive rate was 13.33%, the positive rate of Leptospira was 1.43%. Conclusions The density of mouse-shaped animals in Ningde City, Macao and Hong Kong has not reached the requirement of less than 1% of the rat density as stipulated in the national no-rodent port. The rate of parasite-bearing parasites in mice is low and the species is single. The positive rate of hantavirus is high Strengthen prevention and control to prevent the occurrence of related infectious diseases.
