Activities of beta-lactam antibiotics against Escherichia coli strains producing extended-spectrum beta-lactamases.
Seven extended-spectrum beta-lactamases related to TEM and four enzymes derived from SHV-1 were transferred to a common Escherichia coli host so that the activity of a variety of beta-lactams could be tested in a uniform genetic environment. For most derivatives, penicillinase activity was 10% or le...
