Abstract excerpt
Lactococcus is the causative agent of lactococcosis in fish; however, its genetic characteristics in yellowtail from Japan have not been fully elucidated. In this study, we used whole-genome sequencing (WGS) to investigate virulence genes, antimicrobial resistance genes, and genetic relationships among 40 Lactococcus isolates from diseased yellowtail in 2021. Serotype II accounted for 82.5% of the isolates, while...
