An epizootic of beta-hemolytic Lancefield group G streptococcal infections occurred in a specific-pathogen-free colony of laboratory cats. A total of 19 out of 68 animals in a single building were affected over a 10-day period. Clinical signs included fever, depression, lymphadenopathy, pharyngitis, and submandibular edema. The organism was recovered from the pharynx in two of five clinically normal cats from the affected building. Cultures from 12 animals in the same colony but housed in unaffected buildings were negative. Two doses of long-acting penicillin G 72 h apart stopped the outbreak and resulted in negative cultures for previously affected animals. Three months later, two new cases occurred in the same building. The disease was finally eradicated from the colony by depopulating the affected building.
在一个无特定病原体的实验猫群体中发生了一场由β-溶血性兰斯菲尔德G组链球菌感染引起的 epizootic（动物流行病）。在10天内，一栋楼里68只动物中有19只受到感染。临床症状包括发热、抑郁、淋巴结病、咽炎和下颌下水肿。从受影响楼里五只临床正常的猫中的两只咽部分离出了该病原体。来自同一群体但饲养在未受影响楼里的12只动物的培养物呈阴性。相隔72小时注射两剂长效青霉素G阻止了疫情爆发，并使先前受影响动物的培养物呈阴性。三个月后，同一栋楼里又出现了两例新病例。通过清空受影响的楼，该疾病最终从该群体中根除。
