These studies indicate that a single strain of hemolytic streptococci almost exclusively predominates the bacterial flora in patients with streptococcal infections and in the carrier state. One can proceed with confidence that, in isolating streptococci from throat swabs cultured on blood-agar plates, only a single hemolytic colony need be picked for serological grouping and typing.
这些研究表明，在链球菌感染患者及带菌状态下，几乎仅有一种溶血性链球菌在细菌菌群中占主导地位。因此可以放心地认为，从血琼脂平板上培养的咽拭子中分离链球菌时，只需挑选单个溶血性菌落进行血清学分群和分型。
