Rabbits were infected by intraperitoneal implantation of a chamber with the L-forms of hemolytic streptococcus. Experiments demonstrated that no symptoms of an acute disease followed. Antibodies against the L-form was revealed in the blood serum in low titres. Cardiac valves, particularly the mitral, were affected in all the experiments animals. Histological study showed that changes in the tissues of the heart approched the rheumatic ones by special signs. L-forms were isolated (in the cultures) from the implanted chamber and the blood for up to 15 days after the infection.
通过腹腔植入装有溶血性链球菌L型菌的小室使兔子感染。实验表明，之后并未出现急性疾病症状。血清中检测到低滴度的抗L型菌抗体。在所有实验动物中，心脏瓣膜，尤其是二尖瓣，受到了影响。组织学研究表明，心脏组织的变化在特殊体征方面与风湿性病变相似。感染后长达15天，从植入的小室和血液中（在培养物中）分离出了L型菌。
