Abstract

Streptococcus suis is an important zoonotic agent globally, including Thailand, especially in the northern part, where periodic outbreaks have occurred recently. The aims of this study were to determine the prevalence and antimicrobial susceptibility of S. suis isolated from slaughter pigs in
northern Thailand. A total of 125 salivary glands and 116 tonsillar swabs were collected from 190 slaughter pigs in six slaughter houses during the summer of 2008. In the winter of 2009, 117 salivary glands and 115 tonsillar swabs were collected from 193 slaughter pigs at the same processing plants. Samples were cultured out on Columbia blood agar and the suspected colonies were confirmed by conventional biochemical tests. The prevalence of S. suis isolated from healthy slaughter pigs in northern Thailand sampled in summer and winter was 20% (38/190) and 7.3% (14/193), respectively. Antimicrobial susceptibility testing indicated that the most effective antimicrobial drugs against S. suis were ceftiofur (96%), ampicillin (73%) and amoxicillin (69%), respectively.
