Isolates of beta-hemolytic streptococci obtained from respiratory tract specimens were studied for determination of their serogroup, and Patients' charts were reviewed for the clinical significance of these respiratory isolates. Fifteen of 69 patients were considered to have definite respiratory infection. Thirteen of these 15 patients had Group B beta-hemolytic streptococci. Staphylococcus aureus was isolated concomitantly with Group B streptococci (GBS) in 34% of cases, but rarely was it isolated with other beta-hemolytic streptococci. Sero-groups of beta-hemolytic streptococci were compared with respect to the patient's underlying disease, age, and clinical outcome. Patients who had GBS isolated from sputum were elderly (mean age, 68.1 years) and were older than patients with other beta-hemolytic isolates (mean age, 56 years). Patients with Group B streptococci were more likely to have cerebrovascular disease, whereas patients with Group C, G, and F were more likely to have malignancy, particularly of the head and neck.
对从呼吸道标本中分离出的β溶血性链球菌菌株进行了血清群测定研究，并查阅了患者病历以了解这些呼吸道分离株的临床意义。69名患者中有15名被认为患有明确的呼吸道感染。这15名患者中有13名感染了B组β溶血性链球菌。在34%的病例中，金黄色葡萄球菌与B组链球菌（GBS）同时被分离出来，但很少与其他β溶血性链球菌一起被分离出来。比较了β溶血性链球菌的血清群与患者的基础疾病、年龄和临床结局。从痰液中分离出GBS的患者年龄较大（平均年龄68.1岁），比其他β溶血性分离株患者的年龄大（平均年龄56岁）。B组链球菌感染的患者更易患脑血管疾病，而C、G和F组感染的患者更易患恶性肿瘤，尤其是头颈部肿瘤。
