Emerging MDR producing ESBL among Diarrhoegenic Esherichia coli from paediatric patients

Emerging MDR producing ESBL among Diarrhoegenic Esherichia coli from paediatric patients

Background The beta lactam antibiotics are predominant therapeutic agents against a number of infectious diseases. The production of the enzyme beta lactamase by microbes which hydrolyses the beta lactam antibiotics is an important mechanism of resistance. This study aimed to determine prevalence, phenotypic patterns, and ESBLproduction status both phenotypic and genotypic for the CTX –M type E...

CTX-M15 type ESBL producing Salmonella from a paediatric patient in Chennai, India

Resistance to 3rd generation cephalosporins in Salmonella has been attributed to the production of extended spectrum β-lactamases (ESBLs), but AmpC and KPC or metallo β-lactamase (MBL) mediated resistance have also been reported1. ESBLs reported in Salmonella spp. are the derivatives of TEM, SHV, CTX-M and PER type β-lactamase families1. We isolated Salmonella enterica ser. Typhimurium (B9903) ...

Quinolone resistance mechanisms among extended-spectrum beta-lacta- mase (ESBL)-producing Escherichia coli isolated from farm animals in Switzerland.

Quinolone Resistance Mechanisms among Extended-Spectrum Beta-Lactamase (ESBL) Producing Escherichia coli Isolated from Rivers and Lakes in Switzerland

Sixty extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolated from rivers and lakes in Switzerland were screened for individual strains additionally exhibiting a reduced quinolone susceptibility phenotype. Totally, 42 such isolates were found and further characterized for their molecular (fluoro)quinolone resistance mechanisms. PCR and sequence analysis were performed to identi...

Phenotypic characterization of ESBL producing Enterobacter cloacae among children

OBJECTIVE The emergence of ESBL producing Enterobacter cloacae in clinical isolates is posing a serious threat for treating nosocomial infections. The aim of the study was to determine the frequency of extended spectrum β-lactamase (ESBL) producing Enterobacter cloacae and to compare the phenotypic methods used for the characterization of ESBL producing strains. METHODOLOGY This cross section...
