Six serotypes were found among haemolytic streptococci of Lancefield-group G. Members of these types accounted for about one-third of the strains isolated from human infections and carriers in Nigeria. The type antigens were similar to the M-protein antigens of group-A streptococci in that they were associated with the ability of the streptococci to survive and multiply in fresh human blood unless specific antibody was present. It was also possible to demonstrate in these group-G streptococci and non-type-specific M-associated protein similar to that formed by M-positive strains of group-A streptococci.
在兰斯菲尔德G群溶血性链球菌中发现了六种血清型。这些血清型的菌株约占从尼日利亚人类感染病例和携带者中分离出的菌株的三分之一。这些血清型抗原与A群链球菌的M蛋白抗原有相似之处，即除非有特异性抗体存在，否则它们与链球菌在新鲜人血中存活和繁殖的能力有关。在这些G群链球菌中也能够证明存在与A群链球菌M阳性菌株所形成的类似的非血清型特异性M相关蛋白。
