Meningitis due to Streptococcus suis in Two Patients with Occupational Exposure from Northeastern Brazil.

Streptococcus suis is an emerging zoonotic agent that causes bacterial meningitis. S. suis is an encapsulated Gram-positive, facultative anaerobic bacterium. This infection usually manifests in humans as meningitis, endocarditis, septicemia, and/or arthritis. The primary groups at risk for S. suis infection are individuals occupationally exposed to pigs and/or pork, for example, farmers, butchers, and hunters. Herein, we report two cases of meningitis related to S. suis with occupational exposure from the Ceará state, northeastern Brazil.
