[Lysozyme content in the serum and organs of rabbits with a syphilitic infection].

The levels of lysozyme in the serum and organs of Shienshilla male rabbits infected with Nico-s treponema were determined. The studies showed that the lues infection affected the factors of non-specific immunity, which was evident from the changes in the lysozyme titer. Administration of benzylpenicillin resulted in a marked decrease in the lysozyme titer in all cases. The experiments are indicative of advisability of studying the use of crystalline lysozyme in combination with antibiotics for increasing the efficacy of therapy of syphilitic infection.
