conclusions the levels of resistance to ceftazidime were remarkably variable among ctx-mproducers. this study provides further evidences of the global dissemination of ctx-m type esbls and emphasized on the need for their epidemiological monitoring. results in phenotypic confirmatory test, 154 (44%) out of 350 clinical isolates were esbl positive. using molecular assay, 154 strains potentially ...
The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases bacteria.
Background The extended spectrum ß-lactamases (ESBL) are enzymes that produce resistance to ß-lactam antibiotics, including penicillins, wide spectrum cephalosporins and aztreonam, by cleavage of ß-lactam ring (BUSH & JACOBY, 2010). Since ESBL-producing bacteria are frequently associated with nosocomial infections, treatment options are becoming increasingly limited (RAWAT & NAIR, 2010). In thi...
Emergence of multidrug-resistant strains of Shigella is a growing concern across the globe. Third-generation cephalosporins are used for treating infections caused by multidrug-resistant Shigellae. However, resistance to these cephalosporin antibiotics due to extended-spectrum ß-lactamases, has emerged as a new problem. So far extended-spectrum ß-lactamases producing Shigella has not been repor...
Extended-spectrum ß-lactamases (ESBL) are a major source of concern. ESBL have been recorded around the world. Globally, number people infected with Enterobacteriaceae that produce extended-spectrum beta-lactamase is on rise. It has rise in resistance to ß-lactam antibiotics among them. In this study, objective was collect Escherichia coli isolates from Urinary tract infection patients using se...
Understanding the antibiotic susceptibility of Salmonella enterica is important both from a clinical treatment and a public health perspective. The emergence of extended spectrum ß-lactamases (ESßLs) and AmpC ß-lactamases in S. enterica is important, as this will limit treatment options and could provide a strain with a significant selective advantage. The aim of the study was to screen isolate...
