Research Abstract

In this work, we isolated novel two bacteriophages for Staphylococcus aureus （SA） with wide host ranges from sewage, and examined carefully their potential as therapeutic agents using experimental murine mastitis. All 99 strains of SA isolated from distinct ruminants with mastitis were completely lysed by SA bacteriophage. SA bacteriophage inhibited the SA growth in the mammary gland of experimental murine mastitis.
