extended-spectrum β-lactamase (esbl)-producing enterobacteria has become a considerable global concern because of their potential dissemination in humans, in domestic animals, wildlife and the environment. the present study aimed to explore the esbl producing  enterobacteria in aquatic sources of bangladesh as the water may be the potential source of dissemination of this alarming antimicrobial...

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 ...

background beta-lactam resistance in gram-negative bacteria, especially escherichia coli, is a main clinical problem. it is often caused by the co-production of β-lactamases, particularly extended-spectrum β-lactamases (esbls) and ampc enzymes. it may lead to a problem for diagnosis via recommended phenotypic tests by the clinical and laboratory standards institute (clsi). conversely, β-lactama...

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...

the extended postpartum period is the time which is usually given less emphasis regarding family planning by policy makers, service providers and users. however, it is a time with a rising risk of unwanted conception and an often-frustrated desire for contraceptive protection. understanding the contraceptive behaviors, needs and preferences of women in this period is important the main objectiv...
