Although resistance to the expanded-spectrum cephalosporins among members of the family Enterobacteriaceae lacking inducible β-lactamases occurs virtually worldwide, little is known about this...
Sequencing and analysis of four new Enterobacter ampD Alleles.
Ehrhardt, A F, Sanders, C C, Romero, J R, Leser, J S
Sequences of ampD genes from wild-type, temperature-sensitive, and stably derepressed mutants of the wild-type strain of Enterobacter cloacae 029 and the hyperinducible strain E. cloacae 1194E were...
Penicillin-binding proteins and induction of AmpC beta-lactamase.
Sanders, C C, Bradford, P A, Ehrhardt, A F, Bush, K, Young, K D, Henderson, T A, ...
In competition assays for radiolabeled penicillin, penicillin-binding proteins (PBPs) 4, 7a, and 7b showed very high affinities for strong inducers of AmpC beta-lactamase. Loss of PBP 4 resulted in...
Structure-activity studies of quinolone-penems in genetically defined strains of Escherichia coli.
Quinolonyl-beta-lactam antimicrobial agents (QLAs) contain quinolones chemically linked to beta-lactams, although the impact of linkage is poorly understood. Genetically defined Escherichia coli...
Genetic determinants of host ranges of Bacillus sphaericus mosquito larvicidal toxins.
Berry, C, Hindley, J, Ehrhardt, A F, Grounds, T, De Souza, I, Davidson, E W
The 51.4-kDa-41.9-kDa binary toxin produced by different strains of Bacillus sphaericus shows differential activity toward Culex quinquefasciatus, Aedes atropalpus, and Aedes aegypti mosquito larvae....
