[First case of meningitis by Streptococcus suis in the norwest area of Argentina].

Streptococcus suis causes meningitis, bacteremia, endocarditis, endophthalmitis, artrithis and toxic shock in both pigs and human beings. The incidence of this pathogen is increasing worldwide. A case of 54 years old men from a rural zone of Tucumán, Argentina with two days of headache, vomit and photophobia was admitted septic, with purulent meningitis. Streptococcus suis was growth from the blood and cerebrospinal fluid culture. The patient was treated with ceftriaxona and had a good evolution without sequels. This is the first case of S. suis described in the northwest of Argentina and the third of Latin America, and it is emphasized that the occupational contact with pigs is an important background for the initial suspect of this pathogen.
