[Hyaluronic capsule as one of the factors of hemolytic streptococcal pathogenicity].
Experiments were conducted on albino mice. It was shown that treatment of streptococci with testicular hyaluronidase or a single administration of the enzyme to infected animals failed to inhibit the infectious process. Injection of hyaluronidase solution to every 3 or 4 hours depressed the development of the process and increased the percentage of survived animals during its first stages. A marked intensification of the hyaluronidase action inhibiting the infectious process was observed under conditions of a moderately active or passive immunity and also in the case of preliminary treatment of streptococci with homologous immune serum. The data obtained permit to regard the hyaluronic capsule in the hemolytic streptococci as one of the pathogenicity factors of this microbial species providing survival of the causative agent after its entrance into the macroorganism.
