Abstract Although Streptococcus suis has attracted public attention as a major swine and human pathogen, this bacterium also been isolated from other animals, including ruminants. However, recent taxonomic studies revealed the existence of species that were previously identified S. , some these isolates reclassified novel ruminantium . In Japan, biochemically is frequently diseased ruminants; however, such have not yet accurately, their aetiological importance in ruminants unclear. Therefore, to understand -like bacteria ruminants, we according updated classification investigated genetic diversity. both healthy most animals implying S more likely be associated with ruminant disease than classified into diverse genotypes rather belonging certain clonal groups. Genome sequence analysis 20 provided information about antibiotic resistance, potential virulence, serological diversity species. We further developed an -specific PCR assay aid identification bacterium. The obtained method established study will contribute accurate diagnosis streptococcal infections.
