Serotype Distribution and Pathotypic Characteristics of <i>Streptococcus suis</i> Isolates from Slaughtered Pigs in a High-Density Pig Farming Area in Thailand.

ABSTRACT: Streptococcus suis is a significant bacterial pathogen in the swine industry and represents a zoonotic threat to human health. This study aimed to investigate the prevalence, serotype distribution, and pathotypic characteristics of S. suis isolates obtained from nasopharyngeal swabs of slaughtered pigs in the high-density swine farming region of Thailand. Among 322 swab samples, 194 samples (60.25%) were found to harbor S. suis. The most prevalent serotype was serotype 8 (7.98%), followed by 19 (7.56%), 29 (6.72%), 3 (5.88%), and 2 (5.04%), with 39.92% of isolates classified as non-typeable. Molecular characterization revealed the presence of various clonal complexes (CCs), with CC221/234 being the most prevalent (19.15%). Human-associated clades (HAC) were identified
