Evaluation of methods used for detecting Streptococcus suis type 2 in tonsils, and investigation of the carrier state in pigs.

Streptococcus suis type 2 was isolated from the tonsils of 143 (76 per cent) of 188 pigs from three herds by culturing on media containing a specific antiserum.

The specificity of an indirect fluorescent antibody test for identifying S suis type 2 in mixed cultures was conservatively estimated to be 0.
