Abstract
We determined the antibacterial activity of cephapirin against many strains of following various pathogens by plate-dilution method. We used 593 strains of hemolytic streptococci, enterococci, Staphylococcus aureus, Haemophilus group, several species of Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter and various species of anaerobes isolated from clinical materials in our laboratory during 1972. We compared the antibacterial activity of this drug with cephalothin and cephaloridine.
1) To hemolytic streptococci and Staphylococcus aureus cephapirin is less active than cephaloridine, but to Haemophilus group is more active than cephaloridine.
2) Cephapirin has similar antibacterial activity to cephalothin.
