Streptococcus suis is a bacterial pathogen causing a wide range of infections including meningitis, lung infections, arthritis, sepsis and endocarditis. Over the years, an increasing number of cases have been reported among humans especially in countries in Southeast Asia specifically in Vietnam and Thailand where pig-rearing is common. One of the prominent symptoms of S. suis infection is hearing loss that may be present during the onset or a few days after. We report two cases of adult S. suis meningitis presenting with bilateral hearing loss.
