Rodents are important reservoirs of diseases affecting people and livestock, and are major sources of parasite contamination of agricultural products. We surveyed the infection status of intestinal helminths in 2 species of field mice, Apodemus agrarius and A. peninsulae, captured in the agricultural fields of Gangwon-do and Chungcheongnam-do, Korea. Total 83 mice (57 A. agrarius and 26 A. peninsulae) were collected in 2 surveyed areas, and the intestines of each mouse were opened with scissors, and then intestinal contents were examined with microscope. Total 6 species of intestinal helminth were detected in 61 (73.5%) out of 83 mice examined. Four species of nematode, i.e., Nippostrongylus brasiliensis, Aspiculuris tetraptera, Heterakis spp. and ascarid, were found in 40 (48.2%), 14 (16.9%), 11 (13.3%) and 13 (15.7%) mice respectively. One species of cestode, Hymenolepis diminuta and 1 unidentified egg were also detected in the intestines of 14 (16.9%) and 1 (1.2%) mice, respectively. Conclusively, this study identified 5 helminth species in the gastrointestinal tracts of wild rodents captured in some areas in central and northern Korea, and N. brasiliensis was the most prevalent (dominant) species rather than zoonotic ones.
啮齿动物是影响人类和家畜的疾病的重要宿主,也是农产品寄生虫污染的主要来源。我们调查了在韩国江原道和忠清南道农田捕获的2种田鼠,即黑线姬鼠和半岛姬鼠肠道蠕虫的感染状况。在2个调查区域共收集了83只小鼠(57只黑线姬鼠和26只半岛姬鼠),用剪刀剪开每只小鼠的肠道,然后用显微镜检查肠道内容物。在83只检查的小鼠中,有61只(73.5%)检测到总共6种肠道蠕虫。分别在40只(48.2%)、14只(16.9%)、11只(13.3%)和13只(15.7%)小鼠中发现了4种线虫,即巴西日圆线虫、四翼无刺线虫、异刺属线虫和蛔虫。在14只(16.9%)小鼠的肠道中还分别检测到1种绦虫,即微小膜壳绦虫和1种未鉴定的虫卵,在1只(1.2%)小鼠中检测到未鉴定的虫卵。总之,本研究在朝鲜中部和北部一些地区捕获的野生啮齿动物的胃肠道中鉴定出5种蠕虫,巴西日圆线虫是最普遍(占主导)的物种,而非人畜共患物种。
