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 inhibition zones around the test discs are measured, and compared with the clinical breakpoints for the various antibiotics tested to determine susceptibility (S - Susceptible at standard exposure, I - Susceptible to increased exposure, R - Resistant). The diameter of the inhibition zones corresponds to the susceptibility of the tested bacterial strain to the antibiotic concentration at the edge of the inhibition zone.\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\"\u003emedia library\u003c\/a\u003e.
