[In Vitro]

Cephapirin (Cefapirin) inhibits Staphylococcus aureus by cephapirin concentrations of 0.09 to 12.5 mug/mL[2]. Cephapirin (Cefapirin) inhibits S. epidermidis, S. viridans, S. pyogenes, and Diplococcus pneumonia isolates by less than 1 mug/mL[2].

[In Vivo]

Cephapirin (Cefapirin) (200 mg; i.m.;cows) is effective for cows infected with S. aureus[3].
