This study investigated the bacterial diversity and pathogenic bacteria in the nasal microbiota of wild boars (Sus scrofa) in South Korea, focusing on their potential role as reservoirs for pathogens. A total of 252 nasal swab samples were collected from wild boars in Namwon-si and Muju-gun between November 2023 and May 2024. The samples were analyzed using 16S rRNA sequencing and culture methods. Thirty-six bacterial species were identified, including 13 pathogenic species such as Streptococcus suis, Mycoplasma hyopneumoniae, Staphylococcus aureus, and Escherichia fergusonii. The presence of these pathogens suggests that wild boars may contribute to the spread of zoonotic diseases, posing risks to both livestock and human health. This study provides fundamental data for developing effective disease control and novel insight into nasal microbiota in wild boar in South Korea.
