Abstract
Lysostaphin is used to eliminate and cure staphylococcal infections including the cure of mastitis by intramammary infusion. Administration of from 2 mg to 400 mg of lysostaphin to an infected bovine mammary gland eliminates staphylococci, and the reoccurrence common with antibiotic therapy is not observed. Teat-dips containing lysostaphin, mutanolysin and lysozyme can be used as a prophylactic. Synergistic enhancement of the killing effect of lysostaphin is observed when a mild surfactant or penicillin or both is included in the formulation.
