Sulbactam 94-103 beta-lactamase Escherichia coli 33-36 3263690-8 1988 Synergy between clavulanate or sulbactam (2 micrograms/mL) and amoxicillin was greater against derivatives producing EBS-Bla than against those producing TEM-1, TEM-2, or SHV-1; this synergy was greater with clavulanate than with sulbactam against derivatives producing SHV-2 and the SHV-2-type enzyme but was similar with clavulanate and sulbactam against those producing CTX-1. Sulbactam 31-40 beta-lactamase Escherichia coli 121-124
