[L forms of Streptococcus in the cultures of blood from patients with rheumatic fever in the active and inactive phases].

It was shown that L-forms of streptococci were constantly isolated by means of the method used by the authors from patients with rheumatism, irrespective of the activity and the course of the disease. The data obtained pointed to the presence of septicemia caused by the L-forms of streptococci in patients with rheumatism both at the active and inactive phase. In this connection it should be noted that modern clinical criteria of the activity of rheumatic process are unreliable.
