We studied 13 extended-spectrum beta-lactamase (ESBL)-producing enteropathogenic Escherichia coli isolates from children suffering acute diarrhea in Uruguay. ESBL characterization in crude extracts showed a single band at pI 5.4. PCR amplification and sequencing data allowed identification of blaPER-2 and blaTEM-116. Retrospective analysis suggests that these strains were disseminated in the co...

Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBL-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the antibacterial susceptibility and ESBLs patter...

In modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. Broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as TEM-1, TEM-2, and SHV-1 are transferred among bacterial species. The genes coding the production of ESBL are of...

conclusions according to our results, blatem-116 was the most frequent isolated esbl gene among the p. aeruginosa strains isolated from patients. results ciprofloxacin and piperacillin were the most efficient antipseudomonal agents. the results disclosed that 19 (16.37%) of the isolates were multidrug resistant and 8 (6.89%) were esbl-positive. of the 116 isolates, 30 (25.86%) were resistant to...

Despite of a high abundance antibiotics, heavy metals, and organic matters detected in the Saigon River Ho Chi Minh City, level spread antibiotic resistance genes this river are poorly understood. In study, total 10 (ARGs), including conferring to aminoglycosides (aac(6)-Ib-cr), β-lactam antibiotics (blaCTX-M, blaSHV, blaTEM), quinolones (qnrA, qnrB), sulfonamides (sul1, sul2), trimethoprim (df...

OBJECTIVES To investigate the diversity of plasmids that carry bla(TEM-52) genes among Escherichia coli and Salmonella enterica originating from animals, meat products and humans. METHODS A collection of 22 bla(TEM-52)-encoding plasmids was characterized by restriction fragment length polymorphism (RFLP), replicon typing (by PCR or replicon sequencing), susceptibility testing, assessment of p...
