conclusions according to our results, blatem-116 was the most frequent isolated esbl gene among the p. aeruginosa strains isolated from patients. results ciprofloxacin and piperacillin were the most efficient antipseudomonal agents. the results disclosed that 19 (16.37%) of the isolates were multidrug resistant and 8 (6.89%) were esbl-positive. of the 116 isolates, 30 (25.86%) were resistant to...

background and objectives: β-lactamase production is the predominant mechanism for resistance to β-lactams in enterobacteriaceae. the producing isolates are often multidrug resistant and are major hosts for extended spectrum β-lactamases. this study was designed to determine the prevalence of extended-spectrum β-lactamase producing isolates of escherichia coli and klebsiella pneumoniae and thei...

land. Furthermore, Ct. felis often feeds on humans. Clinicians encountering patients with fever or rash (or both) and a history of cat contact or flea bites should consider a diagnosis of R. felis. Laboratory confirmation of infection is not easy, but in vitro culture of R. felis, and hence material for a serologic assay for the diagnosis of human R. felis infections, has recently been describe...

Recently, tigecycline has been added ...
