- Abstract
Streptococcus suis is a pathogen that affects the industrial production of swine worldwide. It is extremely important, because it is associated with pigs and humans diseases. The aim of this study was to determine the prevalence of Streptococcus suis type 2 in 201 samples of tonsils from clinically healthy animals by the PCR technique. The samples positive for S. suis type 2 were tested for the gene encoding extracellular factors (ef). The results showed that the prevalence (23.38%) was higher than other recent survey in the State, demonstrating that the PCR is a more sensitive method in relation to the bacterial isolation. There was a low occurrence of ef* gene in samples (1.49%) showing great importance to local swine population, because negative strains are potentially less virulent that positive strains.
