This study assessed the prevalence of plague bacterium () among rodents captured in Umzingwane and Nkayi districts, south-western Zimbabwe. A total of 44 rodents were captured on three consecutive days per trapping session in the study sites using a removal trapping method in April 2018. Captured rodents were euthanized, and blood samples were collected. The Giemsa stain method was used to detect plague bacteria. The trapping success was not significantly different (² = 1.50, df = 1, = 0.221), 8.5% for the Nkayi district, while in the Umzingwane district, it was 8%. Overall, only one rodent species, i.e., , tested positive for in the Umzingwane district, thus yielding a prevalence rate of 2.3% for the entire study area. This was the most important finding of a -positive rodent in a non-endemic wild area in the Umzingwane district. These results point to a low prevalence of in the study area and the importance of an active plague disease surveillance and monitoring system.
本研究评估了津巴布韦西南部乌姆津瓦内和恩卡伊地区捕获的啮齿动物中鼠疫杆菌（）的流行情况。2018年4月，在研究地点采用捕获清除法，每个诱捕时段连续三天共捕获44只啮齿动物。捕获的啮齿动物被安乐死，并采集血样。采用吉姆萨染色法检测鼠疫杆菌。诱捕成功率无显著差异（² = 1.50，自由度 = 1， = 0.221），恩卡伊地区为8.5%，而在乌姆津瓦内地区为8%。总体而言，在乌姆津瓦内地区只有一种啮齿动物，即，检测出呈阳性，因此整个研究区域的流行率为2.3%。这是乌姆津瓦内地区非鼠疫流行野生区域中一只呈阳性啮齿动物的最重要发现。这些结果表明研究区域中鼠疫杆菌的流行率较低，以及建立积极的鼠疫疾病监测系统的重要性。
