Abstract

Wild mouse feces can disseminate zoonotic microorganisms throughout a farm, which is a great threat to human health and can lead to economic loss through contaminated agricultural produce. To assess the microbial communities, especially fecal coliform bacteria, we used two methods. First, we isolated bacterial colonies onto the common media LB (lactose broth) agar, TSA (tryptic soy agar), and MRS (de Man, Rogosa, and Sharpe) agar, and then randomly select colonies from each plate and stocked them to the mother plate for genomic DNA isolation. Second, we analyzed bacterial colonies using the 16S rRNA gene molecular diagnostic method. Based on bacterial cultures and bacterial 16S rRNA gene markers, we detected four different bacterial species (Bacillus amyloliquefaciens, Escherichia coli, Staphylococcus xylosus, and Serratia liquefaciens) from fecal coliforms of the striped field mouse Apodemus agrarius and A. peninsulae in agricultural areas in South Korea. These results could help us to better understand the pathogen reservoirs of mice and initiate some preventive measures to mitigate the microbial risks associated with mouse fecal matter in agricultural production areas.
