C. Tarradas et al., IDENTIFICATION OF STREPTOCOCCUS-SUIS ISOLATED FROM SWINE - PROPOSAL FOR BIOCHEMICAL PARAMETERS, Journal of clinical microbiology, 32(2), 1994, pp. 578-580
A study was made of the biochemical profiles of 59 strains serotyped a
s Streptococcus suis, isolated from diseased and clinically healthy pi
gs. The following parameters are proposed for the identification of th
e species: Voges-Proskauer negativity, hydrolysis of esculin positivit
y, trehalose positivity, negativity for growth in 6.5% NaCl, and absen
ce of beta-hemolysis on sheep blood agar. S. suis serotype 2 is negati
ve for hippurate, pyrrolidonylarylamidase, and mannose.
