NANO-RAST: Nano-motion based Resistell AST to determine the antibiotic susceptibility of bacteria causing bacteremia and sepsis.~Study population: patients admitted at the study site with bacteremia considered to be due to a pathogenic strain (E. coli or K. pneumoniae).~Study design: prospective, observational, single arm study.
Blood culture samples from bacteremia patients positive for Gram-negative bacteria will be tested for antibacterial susceptibility using Resistell Phenotech device. The results will be compared with current AST gold standard tests to calculate sensitivity, specificity, and accuracy of Resistell Phenotech device.
