Abstract

|
In this study, the environment of Baegun-myeon, Jinan, Jeonbuk was divided into hills, waterways, reservoirs, Paddy fields and fields, and Sherman traps were installed to capture Wild Rodents for 18 months from March to November 2019 and from March to November 2020. 134 Wild Rodents of 2 classes and 4 species were captured. 119 stripe Apodemus agrarius were dominant species by type. 59 mice were captured at hills by environment. To look at the characteristics of collection by period, there was not much difference during May, June, August, and September excluding March in 2019, and lots of Wild Rodents were captured in March 2020, and thus variation due to climate change in the winter of 2019 and
2020 was identified. As a result of PCR-based DNA test of Leptospira, 4 mice (2.99%) tested positive. As for the periods of their collection, 2 mice tested positive in March, 1 mouse in April, and 1 mouse in November, respectively. To classify the Leptospira-positive Wild Rodents, three mice (75%) were stripe Apodemus agrarius and one mouse (25%) was Apodemus peninsulae. In the future, it is necessary to investigate carriers of Leptospira such as rodents including Wild Rodents over the whole period, not a specific period, given climate change in the Jeonbuk area and the positive reaction to Leptospira found irrespective of seasons. Then, it is judged that prompt and efficient response will be possible in the event of change.
