The culture medium must first be inoculated with a standardized inoculum (EUCAST recommendation: McFarland 0.5) of a fresh pure culture of the bacterial strain to be tested. After a 24-hour incubation, growth is checked, the zones of inhibition around the test discs are measured and compared with the clinical breakpoints for the different antibiotics tested to determine susceptibility (S - Susceptible at standard exposure, I - susceptible to increased exposure, R - Resistant). The diameter of the zones of inhibition corresponds to the susceptibility of the tested bacterial strain to the antibiotic concentration at the edge of the zone of inhibition. \u003cbr\u003e\u003cbr\u003eYou can find various service documents, such as templates with inhibition zone boundaries for easy evaluation of the agar diffusion test and a collection of guidelines in our\u003ca href=\"https:\/\/aurosan.de\/de\/mediathek\/fuer-kunden\"\u003e media library\u003c\/a\u003e.

This means that since EUCAST 10.0 (2020) at the latest, certain antibiotics can only be tested by agar dilution and no longer by agar diffusion (!).
