background and objectives: the pathogenic strains of escherichia coli cause severe septicemia, urinary tract infection and wound sepsis. resistance of this organism to the expanded-spectrum cephalosporins occurs via the production of extended-spectrum β-lactamases (esbls) such as tem and shv. these enzymes hydrolyze oxyimino cephalosporins (cefotaxime, ceftazidime) and monobactams (aztreonam). ...

this study investigated the antibacterial resistance among enterococci isolated in tehran hospitals. a total of 277 enterococcus faecalis, 123 enterococcus faecium and 13 isolates of other enterococcal strains were collected from 1 march 2002 to 15 april 2004 from three teaching hospitals of tehran university of medical sciences. the minimum inhibitory concentrations (mic) of tested antibiotics...

the present study was conducted to investigate antimicrobial resistant pattern of escherichia coli (e. coli) strains isolated from clinical specimens of jordanian pediatric patients during the period from january to december 2008. a total of 444 e. coli strains were isolated from clinical specimens and tested for their susceptibility to different antimicrobial drugs. overall, high resistance ra...

background methicillin-resistant staphylococcus aureus (mrsa) continues to be a major cause of nosocomial infections. methicillin resistance in s. aureus is caused by the acquisition of the meca gene, located on a mobile genetic element called the staphylococcal cassette chromosome (scc). objectives the aim of this study was to evaluate the presence of the predominant sccmec type present among ...

Background: Antimicrobial resistance is a global problem with enormous public health and economic impact. This study was carried out to get an overview of acquired antimicrobial resistance gene sequences in the genomes of Escherichia coli isolated from different food sources and the environment in Nigeria. Methods: To determine the acquired antimicrobial-resistant genes prevalence, genome asse...

background: multidrug resistance in salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. methods: salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to pcr and identified as salmonella enteritidis. for detection and identi...

Introduction: Stenotrophomonas maltophilia is intrinsically resistant to many antimicrobials. Like Pseudomonas spp., this bacterium has a remarkable ability to cause infections, particularly in the respiratory and urinary tracts. This study aims to determine the antimicrobial resistance pattern of S. maltophilia isolates collected from a tertiary care setting and frequency of multi, extensively...

Background: Multidrug resistance in Salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. Methods: Salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to PCR and identified as Salmonella enteritidis. For detection and ide...

Antimicrobial resistance has become one of the most serious public health concerns worldwide. Although circumstances may vary by region or country, it is clear that some Asian countries are epicenters of resistance, having seen rapid increases in the prevalence of antimicrobial resistance of major bacterial pathogens. In these locations, however, the public health infrastructure to combat this ...
