Abstract
Cyclacillin at 50 μg/ml inhibited streptococci (100%), shigella (72%), and Bacteroides (B) fragilis ss fragilis (84%). At 100 μg/ml it inhibited proteus (75%), B. fragilis (86%), and E. coli (50%). Cyclacillin was more effective than ampicillin against β-lactamase-producing H. influenzae. The activity of cyclacillin was found to be more enhanced when tested in nutrient agar and Mueller-Hinton agar than in brain heart infusion agar.Keywords
