Streptococcus suis Meningitis in Humans: the Cause of Emerging Bacterial Infectious Diseases in Brazil? Case Report

Over the past few years, the number of reported human infections caused by ingestion of contaminated food has increased. S. suis infections caused by porcine products in humans present a wide variety of clinical manifestations after they invade the host, such as arthritis, septic shock, polyserositis, meningitis, and endocarditis. This article presents a rare case of meningitis in a Brazilian elderly male after consumption of porcine meat. Bacterial identification was performed with MALDI-TOF, a quick and accurate technique to identify this agent. The minimal inhibitory concentration of ceftriaxone was < 0.12 μg/ml, and the patient underwent a satisfactory course of treatment with ceftriaxone for 14 days. This case shows the importance of adopting sanitary inspection measures in order to avoid potentially lethal events associated with it, during handling, transportation and consumption of porcine meat in a developing country.
