Paradoxical activity of beta-lactam antibiotics against Proteus vulgaris in experimental infection in mice.
In previous papers (Y. Ikeda and T. Nishino, Antimicrob. Agents Chemother. 32:1073-1077, 1988; Y. Ikeda, T. Nishino, and T. Tanino, Antimicrob. Agents Chemother. 31:865-869, 1987), we reported that many of the 7-aminothiazolyl cephalosporins, such as cefmenoxime, showed paradoxically reduced activity against Proteus vulgaris at higher concentrations, whereas these paradoxical effects were not o...
متن کاملThe Survey of Genes Encoding Beta-Lactamases, in Escherichia Coli Resistant to Beta-Lactam and Non-Beta-Lactam Antibiotics
Objective(s) Resistance to the new generation of cephalosporins which is mediated by Extended-Spectrum beta-lactamases (ESBLs) has been found among Escherichia coli isolates throughout the world. These resistance genes and their producers, the micro-organisms carrying beta-lactamases, are responsible for serious clinical and therapeutic problems among inpatients and it is necessary to pay more...

متن کاملBiotypes of Proteus rettgeri.
Examination of 729 isolates of Proteus rettgeri showed that 674 reacted positively in tests for phenylalanine deamination, indole production, growth on citrate, and acid production from meso-inositol, and negatively for L-ornithine decarboxylation and acid production from lactose, maltose, D-xylose, and L-arabinose. Only 51 isolates differed in one, and four differed in two of these ten reactio...
متن کاملPlasmid-mediated carbencillin hydrolyzing beta-lactamases of Proteus mirabilis.
Since ABRAHAM and CHAIN') reported the production of beta((l)-lactamase by Escherichia coli, penicillinases have been shown to play an important role in the resistance of organisms against (3lactam antibiotics2.3). In many cases, the 46lactamases of Gram-negative bacteria have been shown to be mediated by R plasmids'), in contrast to chromosomally encoded drug resistance'). 46-Lactamases of Pro...
