AIM To determine the genetic basis and types of beta-lactamase encountered among enterobacterial isolates of wild pets from the animal exhibit. MATERIALS AND METHODS A total of 17 beta-lactamase-producing enterobacteria recovered from fecal samples of wild pet animals were analyzed for a selected beta-lactamase gene by polymerase chain reaction. RESULTS Molecular analysis identified one or ...

objective(s) resistance to the new generation of cephalosporins which is mediated by extended-spectrum beta-lactamases (esbls) has been found among escherichia coli isolates throughout the world. these resistance genes and their producers, the micro-organisms carrying beta-lactamases, are responsible for serious clinical and therapeutic problems among inpatients and it is necessary to pay more ...

abstract background: pseudomonas aeruginosa is one of the most common gram negative bacteria involved in nosocomial infections. presence of extended-spectrum beta-lactamases (esbls) genes, play an important role in induction of resistance in beta-lactamase producing species to beta lactam antibiotics. frequency of resistance to these antibiotics is increasing. in this study, antibiotic sensitiv...

background extended-spectrum beta-lactamases (esbls) are a group of enzymes that hydrolyze antibiotics, including those containing new cephalosporins, and they are found in a significant percentage of escherichia coli and klebsiella pneumoniae strains. with the widespread use of antibiotics, difficulties with infection therapy caused by drug resistant organisms, especially those that have acqui...

OBJECTIVES This study was conducted to analyse broad-spectrum cephalosporin-resistant Klebsiella oxytoca strains. METHODS The 57 isolates studied were recovered from clinical specimens (n=23) or from rectal swabs (n=34) during a 26-month period. Antibiotic susceptibility patterns were determined using standard agar diffusion and dilution methods including the synergy test between extended-spe...

Emerging antimicrobial resistance rates and Extended-spectrum beta-lactamase producing Escherichia coli recovered from urinary tract infections (UTI) is an increasing problem in specific regions, limiting therapeutic options. One hundred E. coli isolates causing UTI in patients with age from 2 months to 12 years admitted at CMC in the period of April 2009 to March 2010 were tested for antibioti...

In this study, it was aimed to investigate the presence of Klebsiella pneumoniae and phenotypically carbapenemase, extended-spectrum β-lactamase (ESBL), acquired-AmpC beta-lactamase, multiple antibiotic resistance isolates in faeces budgerigars parrots. A total 96 faecal samples belonging 54 42 parrots were used study. Cultivation performed on various media for identification pneuomiae from col...
