Inactivation of {beta}-lactamases from Enterobacter cloacae by monophosphams (1988)

Bush, Karen, Smith, S. A., Tanaka, S. K., Bonner, D. P.

Amongst the monocyclic β-lactam antibiotics, selected monophosphams were potent mechanism-based inactivators of the P99 and E2 cephalosporinases of Enterobacter cloacae. Inhibition of these enzymes...

A number of carbapenem derivatives were examined to determine the structure-activity relationships required for dependence on porin protein D2 for activity against Pseudomonas aeruginosa. As...

Differences in the resistant variants of Enterobacter cloacae selected by extended-spectrum cephalosporins.

Fung-Tomc, J C, Gradelski, E, Huczko, E, Dougherty, T J, Kessler, R E, Bonner, D P

The rates of development of resistance to ceftriaxone, ceftazidime, cefepime, and cefpirome in 10 strains of Enterobacter cloacae were determined by daily transfer for 7 days to fresh medium...

Resistance caused by decreased penetration of beta-lactam antibiotics into Enterobacter cloacae.

Bush, K, Tanaka, S K, Bonner, D P, Sykes, R B

Strains of Enterobacter cloacae were selected on the basis of resistance to aztreonam, ceftazidime, moxalactam, or imipenem. All strains produced the same E2 beta-lactamase, with an isoelectric point...
