Antibiotic susceptibility testing for the control of antibiotic resistance mechanisms helps in indicating the antibiotic type which is apt for treating a particular infection further, avoiding unnecessary prescription of antibiotics in order to cut down on healthcare costs. Your provider may start you on one antibiotic, but later change you to another because of the results of sensitivity analysis. In the case of bacteria, this approach permits the selection of antibiotics that will be most effective in dealing with the. Materials and methods. pylori infection in part due to difficulty accessing H. The technique called the fast antibiotic susceptibility test (fASTest), detects the level of antibiotic resistance or susceptibility in Escherichia coli and is quick enough to enable a doctor to prescribe patients the correct antibiotics during their first appointment.
