title: In vitro and in vivo microbiological evaluation of Cephapirin, a new antibiotic.
abstract: The microbiological properties of cephapirin, a new semisynthetis cephalosporin, have been studied. This antibiotic, if compared with ampicillin, shows a greater activity against gram positive bacteria, a lack of sensitivity to staphlococcal beta-lactamase, and a lower sensitivity to those produced by gram-negative bacteria. Useful therapeutic of cephapirin levels can be detected in human serum 6 h after administration of 500 and 1,000 mg parenterally.
