Introduction
Streptococcus suis , a gram-positive, facultative anaerobic bacterium, is an emerging zoonotic pathogen [1]. S. suis is endemic in the upper respiratory tract of pigs, particularly in the tonsils and nasal cavity, but it can also be found in the genitalia and gastrointestinal tract [2, 3]. Although multiple serotypes can infect pigs, S. suis serotype 2 is the most common human pathogen [2, 3]. As of 2012, 1,584 human cases of S. suis serotype 2 have been reported [4]. S. suis infections are more prevalent in Southeast Asia owing to the high consumption of pork and frequent small-scale pig rearing [5-7]. People with occupations that involve contact with pigs or pork, such as slaughterhouse workers and butchers, are at a particularly high risk of S. suis infection [8].
The characteristic clinical manifestation of S. suis infection in humans is meningitis [4, 9]. Irreversible hearing loss and vestibular dysfunction are well-known complications of S. suismeningitis [4, 10], and its causes, treatments, and predictive scores have been investigated [11]. However, the underlying causes of less frequent complications, such as ventriculitis, are poorly understood [4, 10]. Herein, we report a case of meningitis with pyogenic ventriculitis associated with S. suis infection.
