牡丹江市三道关林区野生鼠总科动物感染绦虫和蛔虫的情况调查

Investigation on the Infection of Muroidea with Tapeworm And Ascaris in Sandaoguan Forest Area of Mudanjiang

为调查牡丹江市三道关林区野生鼠总科(Muroidea)动物组成情况以及鼠总科动物感染绦虫和蛔虫的情况,采用铗日法,于2023年3—10月在牡丹江市三道关林区利用捕鼠笼捕捉野生鼠总科动物。将捕捉到的野生鼠总科动物根据形态学特征进行分类并解刨,将小肠用生理盐水冲洗,取出虫体后,在显微镜下进行形态学分析并判断其种属,分析并记录各种野生鼠总科动物感染绦虫和蛔虫的情况。结果表明:在牡丹江市三道关林区不同生境共捕获野生鼠总科动物247只,隶属于1目2科3属5种,其中包括大林姬鼠(Apodemus peninsulae)、黑线姬鼠(Apodemus agrarius)、棕背鼠平(Myodes rufocanus)、东方田鼠(Microtus fortis)、大仓鼠(Tscherskia triton),种类组成以大林姬鼠和黑线姬鼠为主,分别占40.89%和34.01%;经形态学鉴定,感染的绦虫均为缩小膜壳绦虫(Hymenolepis dimimula),三道关林区野生鼠类感染缩小膜壳绦虫和蛔虫的概率分别为2.43%、1.62%。其中,大林姬鼠感染缩小膜壳绦虫的概率为2.97%,黑线姬鼠感染缩小膜壳绦虫的概率为4.76%,黑线姬鼠感染蛔虫的概率为4.76%,其余鼠未见有感染。综上所述,三道关野生鼠总科动物感染缩小膜壳绦虫的概率较全国其他省份低,但出现蛔虫感染现象,对人类健康构成一定威胁,相关部门应加强鼠患和寄生虫的防治工作。

In order to investigate the composition of wild rodents and the infection of tapeworm and roundworm in Sandaoguan forest area of Mudanjiang City,the experiment had been conducted by using the Force-day method to capture wild murinoidea in the Sandaiguan forest area of Mudanjiang City from March 2023 to October 2023.The captured wild rats were classified and dissected according to morphological characteristics,and the small intestine was removed and rinsed with normal saline.After the worm body was removed,morphological analysis was performed to determine its species,and the infection situation of various rat tapewormsand roundworms was analyzed and recorded.The results showed that a total of 247 rodents belonging to 1 order,2 families,3 genera and 5 species were captured in different habitats in Sandaiguan forest area of Mudanjiang City,including Apodemus Peninsulae,Apodemus agrarius,Myodes rufocanus,Microtus fortis,Tscherskia triton.The species composition was dominated by Apodemus peninsulae and Apodemus agrarius,accounting for 40.89%and 34.01%,respectively.Morphological identification showed that the infected tapeworms were all Hymenolepis dimimula,and ascarids belong to the Ascaris genus.The overall infection rates of Hymenolepis dimimula and Ascaris were recorded as 2.43%and 1.62%of Wild rodents,which had been caught in Sandaoguan forest.Among them,the incidence of Hymenolepis dimimula was 2.97%in Apodemus peninsulae and 4.76%in Apodemus agrarius.The infection rate of Ascaris in Apodemus agrarius was 4.76%,and no infection was found in other rats.In conclusion,the infection rate of the wild rodents in Sandaoguan is lower than that in other pr-ovinces of China.However,the phenomenon of roundworm infection poses a certain threat to human health.The relevant departments should strengthen the preventionand control of rodents and parasites.
