Sorotipos de Streptococcus suis identificados em suínos com meningite no estado do Paraná

A total of 76 samples of Streptococcus suis isolated from meningitis cases in pigs from 2005 to 2009 were evaluated. The samples were collected from 3 to 21-week-old pigs raised in 30 farms located in Parana state, Brazil. The samples of S. suis were obtained as part of routine procedures and were serotyped by coagglutination test using rabbit hyperimmune sera for the serotypes 1 to 9 and ½. S. suis type 2 was the most frequent, followed by serotypes 1, ½ and 3.
