Abstract
Streptococcus suis is an important pig pathogen which is associated with respiratory problems, meningitis and less fre-quently with a variety of other conditions(Hommez et al. 1986). S. suis type 1 causes disease mainly in 1–2 week old pigs while serotype 2 is found commoaily in 2–22 week old pigs, S. suis type 2 is a zoonosis. It can cause meningitis and septicaemia in man (Christensen & Kronvall 1985). Several other serotypes of S. suis have also been identified on the basis of the capsular poly-saccharide (Perch et al. 1983, Hommez et al. 1986). We present a case where we isolated S. suis types 1 and 2 from the brain and lungs respectively of the same diseased suckling piglet. This i/s the first reported case of S. suis types 1 and 2 in Finland.
