Effects of muramyl dipeptide treatment on resistance to infection with Toxoplasma gondii in mice.

abstract：:Despite effective antimicrobial chemotherapy, control of Chlamydia trachomatis urogenital infection will likely require a vaccine. We have assessed the protective effect of an outer membrane protein-based vaccine by using a murine model of chlamydial genital infection. Female mice were first vaccinated with Chlamydia ...
