于2022年10—11月选择安徽省沿江地区的芜湖市、马鞍山市、铜陵市、安庆市、池州市、宣城市等6个市的38个乡（镇）50个行政村开展野鼠寄生虫感染情况调查，采用夹（笼）夜法捕捉野鼠。鉴定鼠种后，剖解肝脏和肠系膜组织，采用组织活检或压片镜检法检测寄生虫感染情况，同时收集野鼠粪便，采用改良加藤厚涂片法（Kato-Katz法）进行虫卵检测。采用SPSS 23.0软件对感染率差异进行χ²检验。共捕获野鼠1 703只，寄生虫感染阳性678只，平均感染率为39.81%，宣城市、芜湖市和安庆市感染率较高，分别为77.50%（62/80）、72.97%（54/74）和64.00%（272/425）。雌鼠931只、雄鼠769只、3只性别不明，感染率分别为40.92%（381/931）、38.49%（296/769）和1/3，雌鼠和雄鼠感染率差异无统计学意义（χ² = 1.040，P > 0.05）。捕获的野鼠以黄毛鼠、黑线姬鼠和黄胸鼠为主，分别占41.87%（713/1 703）、38.64%（658/1 703）和11.27%（192/1 703），感染率分别为34.64%（247/713）、40.58%（267/658）和61.46%（118/192），不同鼠种间感染率差异有统计学意义（χ² = 48.484，P < 0.01）。678只野鼠感染的寄生虫包括钩虫、蛔虫、肝毛细线虫、短膜壳绦虫、长膜壳绦虫、姜片吸虫、鞭虫和后睾吸虫。单一感染的野鼠占78.61%（533/678），感染2种寄生虫的野鼠占20.21%（137/678），感染3种寄生虫的野鼠占1.18%（8/678）。安徽省沿江地区野鼠寄生虫感染较为普遍，应加强野鼠监测，以降低对人群的感染风险。

The prevalence of parasitic infections was investigated in wild mice in 50 administrative villages across 38 townships in 6 cities of Wuhu, Ma’anshan, Tongling, Anqing, Chizhou, and Xuancheng in Anhui Province from October to November 2022. Wild mice were captured with baited traps or cages at night, and characterized for species. Then, mice were sacrificed, and the liver and mesenteric tissues were dissected and examined for parasitic infections using tissue biopsy or microscopy. Mouse stool samples were collected and tested for parasite eggs using the modified Kato-Katz thick smear technique. The differences in infection rates were analyzed using the χ² test in SPSS 23.0 software. A total of 1 703 wild mice were captured, and 678 were tested positive for parasitic infections, yielding an overall infection prevalence rate of 39.81%. The three cities with the highest prevalence included Xuancheng City (77.50%, 62/80), Wuhu City (72.97%, 54/74), and Anqing City (64.00%, 272/425). The captured mice included 931 females, 769 males, and 3 of unknown sex, and the infection rates were 40.92% (381/931), 38.49% (296/769) and 1/3, respectively, with comparable prevalence between male and female mice (χ² = 1.040, P > 0.05). Rattus losea (41.87%, 713/1 703), Apodemus agrarius (38.64%, 658/1 703) and R. tanezumi (11.27%, 192/1 703) were predominant mouse species, with prevalence rates of 34.64% (247/713), 40.58% (267/658) and 61.46% (118/192), respectively, and there was a mouse species-specific prevalence rate of parasitic infections (χ² = 48.484, P < 0.01). Parasites detected in the 678 infected rodents included hookworm, Ascaris lumbricoides, Capillaria hepatica, Hymenolepis nana, H. diminuta, Fasciolopsis buski, Trichuris trichura and Opisthorchis. Mono-infection accounted for 78.61% (533/678) of wild mice, and co-infections with two parasite species occurred in 20.21% (137/678), while triple infections with three parasite species occurred in 1.18% (8/678). The findings indicate that parasitic infections are highly prevalence in wild mice in Anhui Province, which poses a risk to human parasitic infections. Intensified monitoring of parasitic infections is recommended in wild mice.
