A Case of Life-Threating Streptococcus suis Infection Presented as Septic Shock and Multiple Abscesses

Streptococcus suis is a zoonotic pathogen that can cause severe systemic infections in humans as well as swine. In recent decades, the number of S. suis infections in humans has increased, particularly in Southeast Asia. Although most cases of S. suis human infections are reported as sporadic, a few outbreaks have been noted. Interestingly, these outbreaks have been proposed to be associated with concomitant outbreaks in swine. In Korea, four sporadic and non-fatal cases of S. suis infection have been reported. We herein report a case of life-threating S. suis infection with sepsis for the first time in Korea. The patient was a healthy pig farmer, and the gastrointestinal tract was considered the route of infection. This case emphasized the need for awareness and recognition of S. suis as a zoonotic pathogen.
