Abstract:

Objective To investigate the species composition of murine-like animals in the Macheng city, Yingshan county, Suizhou city, Xian'an district, Chongyang county, and Xingshan county of Hubei province, China, where there has been high incidence of severe fever with thrombocytopenia syndrome (SFTS), and to provide a scientific basis for the control of this disease. Methods The night trapping method was used to capture murine-like animals. Results Niviventer confucianus was the dominant species outdoors in Guangshui county and Sui county of Suizhou city, accounting for 58.88% of all captured rodents in this area. N. confucianus was the dominant species in Xian'an district, accounting for 68.18% of all captured rodents in this area. Crocidura attenuata was the dominant species in Macheng city and Xingshan county, accounting for 40.48% and 66.67%, respectively, of all captured rodents in local areas. Rattus tanezumi was the dominant species in Yingshan county and Chongyang county, accounting for 43.75% and 47.06%, respectively, of all captured rodents in local areas. Most of captured rodents were female. Conclusion The species composition of outdoor rodents varies greatly between the epidemic areas of SFTS in Hubei province, with N. confucianus, R. tanezumi, and C. attenuata as the dominant species, and most of the captured rodents are female.

摘要：

目的 在湖北省发生较多发热伴血小板减少综合征病例的麻城市、英山县、随州市、咸安区、崇阳县、兴山县区域开展鼠形动物种群构成调查,为控制该疾病的传播流行提供科学依据。方法 采用夹夜法捕获鼠形动物。结果 随州市的广水县和随县室外以北社鼠为优势种,占该地捕获总数的58.88%;咸安区以北社鼠为优势种,占该地捕获总数的68.18%;麻城市和兴山县均以灰麝鼩为优势种,分别占40.48%和66.67%;英山县和崇阳县均以黄胸鼠为优势种,分别占43.75%和47.06%。所采集到的不同种鼠类均以雌性鼠为主。结论 湖北省发热伴血小板减少综合征发病区域室外鼠种类构成差异较大,主要以北社鼠、黄胸鼠和灰麝鼩为优势种,且捕获的鼠类绝大多数为雌鼠。
