Culture-Based Antimicrobial Susceptibility Testing for Helicobacter pylori
Abstract
Culture-based antimicrobial susceptibility testing is a crucial method for the management of Helicobacter pylori infection . It must follow the European Committee on Antimicrobial Susceptibility Testing (EUCAST) recommendations for fastidious microaerophilic bacteria, with some possible variation especially for the medium to be used. It is recommended to test six antibiotics by diffusion using strips charged with an antibiotic gradient in order to determine the minimum inhibitory concentrations (MICs). Two of these antibiotics, clarithromycin and levofloxacin, are more important because of frequent resistance which jeopardizes the success of the treatment.
