Antimicrobials: Susceptibility Testing


The ability of bacteria to resist the damaging effects of antimicrobials may be a normal characteristic of a particular species or may be acquired by a variety of genetic changes. Testing of bacteria to determine whether or not resistance is present is called susceptibility testing because the most frequent reasons for carrying out such tests is to monitor antibiotics to confirm that they are suitable for treatment of bacteria isolated from individual patients.

Keywords: antimicrobials; susceptibility testing; antibiotic resistance; inhibitory concentrations of antibiotics
