Pseudomonas cepacia susceptibility to sulbactam

Abstract
For 25 of 32 Pseudomonas cepacia isolates, predominantly from sputum of adult patients, agar dilution MICs of sulbactam were 2.5 micrograms/ml, and for only one was the MIC more than 80 micrograms/ml. Susceptibility was reliably predicted by response to a commercial sulbactam-ampicillin disk.
