Evolutionary Trajectories of Beta-Lactamase CTX-M-1 Cluster Enzymes: Predicting Antibiotic Resistance

Extended-spectrum beta-lactamases (ESBL) constitute a key antibiotic-resistance mechanism affecting Gram-negative bacteria, and also an excellent model for studying evolution in real time. A shift in the epidemiology of ESBLs is being observed, which is characterized by the explosive diversification and increase in frequency of the CTX-M-type beta-lactamases in different settings. This provides...

A novel CTX-M beta-lactamase (CTX-M-8) in cefotaxime-resistant Enterobacteriaceae isolated in Brazil.

To estimate the diversity of extended-spectrum beta-lactamases in Brazil, 18 strains from different species of the family Enterobacteriaceae exhibiting a positive double-disk synergy test were collected by a clinical laboratory from several hospitals in Rio de Janeiro, Brazil, in 1996 and 1997. Four strains (Proteus mirabilis, Enterobacter cloacae, Enterobacter aerogenes, and Citrobacter amalon...

Prevalence of SHV/CTX-M/TEM (ESBL) Beta-lactamase Resistance Genes in Escherichia Coli Isolated from Urinary Tract Infections in Tehran, Iran

Abstract Background and objectives: Beta-lactamase enzymes are the most causes of resistance to antibiotics among gram-negative bacteria. Nowadays, Infections due to ESBLs are being increased throughout the world and is considered as a new burden to the health systems. This study aimed at determining the sensitivity pattern of E.coli isolates to beta-lactam antibiotics, and investigating the pr...

The Prevalence of CTX-M Beta-Lactamase Gene in Urinary Tract Infections in patients referring to Bonab city Hospitals

Background: Urinary Tract Infection (UTI) is one of the most common bacterial infections, and several studies have reported the prevalence of UTI caused by ESBL-producing E.coli strains in different cities of Iran. The aim of this study was to evaluate antibiotic resistant UTI factors in outpatients and determine the prevalence of ctx-m gene in ESBL-producing E. coli strains of Bonab (East Azer...
