Investigation on the Infection of Muroidea with Tapeworm And Ascaris in Sandaoguan Forest Area of Mu-danjiang
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 ac-cording 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 round-worms 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 inci-dence 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.
