A study was made of the biochemical profiles of 59 strains serotyped as Streptococcus suis, isolated from diseased and clinically healthy pigs. The following parameters are proposed for the identification of the species: Voges-Proskauer negativity, hydrolysis of esculin positivity, trehalose positivity, negativity for growth in 6.5% NaCl, and absence of beta-hemolysis on sheep blood agar. S. suis serotype 2 is negative for hippurate, pyrrolidonylarylamidase, and mannose.
对从患病猪和临床健康猪中分离出的59株血清型为猪链球菌的菌株进行了生化特征研究。提出了以下用于鉴定该物种的参数:Voges-Proskauer试验阴性、七叶苷水解阳性、海藻糖阳性、在6.5%氯化钠中生长阴性以及在绵羊血琼脂上无β溶血。猪链球菌2型对马尿酸盐、吡咯烷酮芳基酰胺酶和甘露糖呈阴性。
