DEL'ARCO, A.E. et al. Swine infection by Streptococcus suis: a retrospective study. Arq. Bras. Med. Vet. Zootec. [online]. 2008, vol.60, n.4, pp. 878-883. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352008000400016.
The epidemic aspects of swine infections caused by Streptococcus suis were studied, focusing mainly on the occurrence of several serotypes. A total of 323 samples of S. suis were isolated from clinically ill animals, serotyped according to the co-agglutination procedure, and analyzed. The serotyping revealed that S. suis was present in several Brazilian states. The largest number was isolated from the states of Minas Gerais (62.5%), São Paulo (10.8%), and Paraná (9.3%). Serotype 2 was the most frequent (61.0%), followed by the serotypes 1, 3, 4, 7, and 8. The largest number of isolations was obtained from the brain (60.1%), followed by the lungs (10.4%). About 9.4% of the cases were due to septicemia.
