Bacterial colonies and viable bacterial burden in wound tissue were assessed on day 3 in a mouse model of MRSA (USA300)-infected wounds. Penicillin G (Penicillin G potassium; 100 μM; topical application to the wound; twice daily at 10 µL each time) significantly reduced the viable MRSA burden in the wound tissue.
