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 and objective: organisms producing ctx-m β-lactamases are emerging as a source of resistance to oxyiminocefalosporins such as ceftriaxone and ceftazidime. however, the laboratory detection of these strains is not well defined. in this study, phenotypic assay for screening of extended-spectrum β-lactamases producing strains and molecular assay for the identification of ctx-m β-lactama...

conclusions this study showed that multiple β-lactamases can be produced in burn isolates. this suggests that use of cephalosporins and carbapenems should be restricted in burn isolates to minimize the development and spread of these multidrug resistant pathogens. results there was 99% resistance to carbenicillin, and ticarcillin, 98% to cotrimoxazole, 96% to ciprofloxacin, and aztreonam, 95% t...
