- Abstract
- Streptococcus suis is a major pig pathogen causing severe economic losses to the swine industry. This study aimed to analyze the genome of S. suis strain INT-01 isolated from a domestic pig in Korea. We found that the genome of strain INT-01 contains 2,092,054 bp, with a guanine (G) + cytosine (C) content of 41.3%, and the capsular polysaccharide synthesis locus of this strain is almost identical to that of serotype 3 S. suis strain 4961 isolated from China, suggesting that these isolates can be classified as serotype 3. Genomic analyses revealed that strain INT-01 is an extracellular protein factor (epf)(-)/ muraminidase-released protein (mrp)(+)/ suilysin (sly)(-) S. suis, which is the most prevalent genotype in Korea, and several virulence-related genes associated with the pathogenicity of S. suis were also detected. The genomic information of strain INT-01 may provide important insights into the development of control strategies against S. suis infections in Korea.
