Abstract

Abstract:

To understand the distribution of zoonotic parasite infections in the wild mice, the wild environment of 13 administrative villages in 9 counties (districts) of Wuhu City, Anhui Province was selected to capture wild mice in October, 2022. The mice species and gender were identified and age was determine according to the weight. Fecal samples were collected and eggs were detected by the modified Kato thick smear method (Kato-Katz method). The liver, mesentery and other tissues of the wild mice were collected, and parasite infection was detected by tissue biopsy or tablet microscopy. SPSS 26.0 software was used for statistical analysis. The χ² test was used to compare between groups. The results showed that the total infection rate of wild mice parasites in the 13 surveyed villages in 9 counties (districts) was 78.1% (125/160). Except for Sanshan District (2/2), the infection rate of wild mice in Jiujiang District (90.3%, 28/31) was the highest, and the difference was statistically significant compared with that in Economic Development District (52.2%, 12/23) and Nanling County (3/6) (χ² = 8.253, 6.016, both P < 0.05). Eggs of six parasite species were detected by Kato-Katz method, with detection rates of hookworm 72.5% (116/160), Ascaris sp. 2.5% (4/160), Capillaria hepatica 4.4% (7/160), Syphacia spp. 1.9% (3/160), and Hymenolepis diminuta 5.6% (9/160) and Hymenolepis nana 3.1% (5/160). Two parasite species, C. hepatica and hookworm, were detected by tissue biopsy or microscopic examination, with detection rates of 1.3% (2/160) and 3.1% (5/160), respectively. The proportion of wild mice infected with a single parasite was 84.8% (106/125) and the proportion of wild mice infected with two or more parasites was 15.2% (19/125). Among the 160 wild mice, Rattus tanezumi and Apodemus agrarius had parasite infection rates of 78.6% (99/126) and 76.5% (26/34), respectively (χ² = 0.403, P > 0.05). The parasites infection rates between male and female mice were 79.7% (59/74) and 76.7% (66/86), respectively (χ² = 0.207, P > 0.05). The parasite infection rates of juvenile mice, subadult mice and adult mice were 68.8% (33/48), 81.7% (89/109) and 3/3, respectively (χ² = 3.659, P > 0.05). Parasitic infection in wild mice was widely present and diverse in Wuhu City, Anhui Province. The local population is at risk of infection with zoonotic parasites.
