background :  pathogenic bacteria because of beta-lactam antibiotic resistance genes are dangerous to society. this resistance due to esbl genes, plasmids and transposons that by receiving or mutation occurs. the most important factor beta-lactam antibiotic resistance is beta lactamase enzymes. the purpose of this study was to evaluate the frequency of hospital opportunistic pathogenic bacteria...

background: and objectives: salmonella infections are endemic in many developing countries with poor sanitary conditions, but emerge sporadically as a serious public health threat in developed countries. infections with multidrug resistant (mdr) strains of salmonella have been associated with treatment failures. salmonella spp. resistant to extended spectrum cephalosporins are increasing in pre...

Background: ESBL producing bacteria poses a major problem for clinical therapautics. The ESBL producing isolates of E.coli among other clinical isolates has been increasing over the past few years resulting in limitation of therapeutic options. Materials and methods: A total number of 20 clinical specimens of E.coli were obtained from different clinical samples. They were subjected for the anti...
