The interaction of ampicillin and chloramphenicol on three ampicillin-susceptible, chloramphenicol-resistant strains of Haemophilus influenzae was studied by checkerboard testing with subcultures, time-kill experiments, and a disk method. In all three strains there was inhibition of the bactericidal action of ampicillin by chloramphenicol at concentrations close to the MIC (10 micrograms/ml). T...

Previous studies with beta-lactamase-negative, ampicillin-resistant (BLNAR) Haemophilus influenzae from Japan, France, and North America indicate that mutations in ftsI encoding PBP3 confer ampicillin MICs of 1 to 4 micro g/ml. Several BLNAR strains with ampicillin MICs of 4 to 16 micro g/ml recently isolated from North America were studied. Pulsed-field gel electrophoresis identified 12 unique...

Twenty-seven Navajo adults with moderate to severe acute inflammatory diarrhea were hospitalized and randomly given ampicillin or sulfamethoxazole-trimethoprim. All patients had invasive diarrhea as defined by sheets of fecal leukocytes, seen on methylene blue wet-slide preparations, and significant clinical symptoms, including postural hypotension from dehydration or fever (temperature greater...

Kinetic studies of ampicillin action were made on exponentially growing Escherichia coli and on E. coli-spheroplasts using a range of inhibitory and subinhibitory concentrations of ampicillin. For each concentration, the value (ko--ka) representing the difference in generation rates of ampicillin-free culture (ko) and the generation rate of the culture with ampicillin (ka) was calculated and pl...
