Ten antisera, prepared against nine selected strains of group-G streptococci and a strain of group-A streptococci of M-type 12, were used to serotype 102 isolates of group-G streptococci by means of precipitation reactions between the sera and hot-acid extracts of the streptococci. Fifty-six (54.9%) of the streptococci could be typed; eight serotypes were identified, of which type VIII was the most common (18.6%). The M12 and the R28 antigens, previously recorded in group-G streptococci, were not detected. The type antigens were trypsin sensitive and resembled the M antigens of group-A streptococci.
针对9株选定的G群链球菌和1株M12型A群链球菌制备了10种抗血清，通过抗血清与链球菌热酸提取物之间的沉淀反应，对102株G群链球菌分离株进行血清分型。其中56株（54.9%）链球菌能够分型；鉴定出8种血清型，其中VIII型最为常见（18.6%）。先前在G群链球菌中记录的M12和R28抗原未被检测到。这些型抗原对胰蛋白酶敏感，类似于A群链球菌的M抗原。
