Abstract
β-Lactamase negative (β-lac−) and positive (βlac+) strains of Neisseria gonorrhoeae and Haemophilus Influenzae were tested for susceptibility to piperacillin and seven other beta-lactam antibiotics. Piperadillin was the most active penicillin on the β-lac− and β-lac+ gonococci. All penicillins were very active on β-lac−H. Influenzae, but carbenicillin and ticarcillin were most active on β-lac+ strains; piperacillin was more active than ampicillin on those strains. Cefamandole was the most active cephalosporin tested against both genera, and did not significantly vary for β-lac− and β-lac+ strains.Keywords
