Monobactams containing 3 beta-aminothiazolyl oxime side chains (SQ 81,377, SQ 81,402, azthreonam, and SQ 26,917) have poor affinities for the broad-spectrum beta-lactamases TEM-2 and K1. Addition of a 4-methyl substituent significantly increased stability to hydrolysis by these enzymes. P99 cephalosporinase from Enterobacter cloacae was strongly inhibited by the monobactams. Interaction of azth...
A new natural IND-type metallo-beta-lactamase variant, IND-5, was identified in a clinical isolate of Chryseobacterium indologenes. IND-5 shared 92.8% and 92.4% amino acid homology with IND-1 and IND-3, respectively. Purified enzyme (pI = 8.8, M(r) = 25,000) was able to hydrolyze penicillins, some narrow- and expanded-spectrum cephalosporins, and carbapenems but not monobactams.
Pseudomonas alcaligenes, a Gram-negative aerobic bacterium, is a rare opportunistic human pathogen. Here, we report the whole-genome sequence of P. alcaligenes strain MRY13-0052, which was isolated from a bloodstream infection in a medical institution in Japan and is resistant to antimicrobial agents, including broad-spectrum cephalosporins and monobactams.
We evaluated the in vitro activities of 21 different antimicrobial agents against nine clinical isolates of Flavimonas oryzihabitans obtained from patients with cancer. The organisms were susceptible to most agents commonly used for the empiric therapy (aminoglycosides, ureidopenicillins, extended-spectrum cephalosporins, monobactams, and carbapenems) and prevention of infections (quinolones an...
