A study of hemolytic streptococci from clinical infections in dogs revealed the presence of four serogroups, with one to four biotypes in each, based on carbohydrate fermentation patterns. Of 254 isolates tested, 206 belonged to Lancefield group G, 30 to group C, 7 to group E, and 1 to group A. Ten isolates could not be grouped. Reactions on the three key carbohydrates, lactose, trehalose, and sorbitol, revealed four biotypes each in groups G and C, and two in group E and among the ungroupable cultures. The most common pattern, seen in 154 cultures, was lactose fermentation with no action on trehalose and sorbitol, and corresponded to that described for Streptococcus canis (Stafseth et al., J. Am. Vet. Med. Assoc. 90:769-781, 1937). Most of the strains originated from skin, subcutaneous and wound infections, genitourinary lesions, otitis externa, and respiratory disease. Data suggest that group G streptococci may be preferentially parasites of the urogenital tract.
一项对犬临床感染中溶血性链球菌的研究表明，根据碳水化合物发酵模式，存在四个血清群，每个血清群有一至四种生物型。在测试的254株分离株中，206株属于兰斯菲尔德G群，30株属于C群，7株属于E群，1株属于A群。10株分离株无法分型。对三种关键碳水化合物（乳糖、海藻糖和山梨醇）的反应表明，G群和C群各有四种生物型，E群和无法分型的培养物中有两种生物型。在154个培养物中观察到的最常见模式是乳糖发酵，对海藻糖和山梨醇无作用，这与犬链球菌（Stafseth等人，《美国兽医医学协会杂志》90:769 - 781，1937年）所描述的一致。大多数菌株源自皮肤、皮下和伤口感染、泌尿生殖系统病变、外耳道炎和呼吸道疾病。数据表明，G群链球菌可能是泌尿生殖道的优先寄生菌。
