abstract background: the invasion of microorganisms into the bloodstream and spread to different parts of body can cause disruption the functions of vital organs and even death. the proper and prompt treatment is essential and can significantly reduce morbidity and mortality rates. this study aimed to determine the frequency and the antimicrobial susceptibility of bacteria isolated from blood c...

Antimicrobial susceptibility testing with phenotypic methods requires breakpoints, i.e. a minimum inhibitory concentration (MIC) categorizing micro-organisms into susceptible, intermediately susceptible, and resistant for the relevant antimicrobial agent. Determinations of breakpoints require tools such as the understanding of dosing, MIC distributions of organisms without resistance mechanisms...

To assess the relatedness of Streptococcus pneumoniae isolates recovered concurrently from blood and respiratory tract specimens from patients with pneumonia, we analyzed 24 paired isolates by pulsed-field gel electrophoresis (PFGE), serotyping, and antimicrobial susceptibility testing. PFGE, serotype, and/or susceptibility patterns were identical for 22 of 24 pairs. Susceptibility results for ...

Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBL-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the antibacterial susceptibility and ESBLs patter...
