The culture medium must first be inoculated with a standardised inoculum (EUCAST recommendation: McFarland 0.5) of a fresh pure culture of the bacterial strain to be tested. After 24 hours of 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 - Intermediate, R - Resistant). The diameter of the inhibition zones corresponds to the susceptibility of the bacterial strain tested 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 limits for easy evaluation of the agar diffusion test, a collection of guidelines and application videos in our \u003ca href=\"https:\/\/aurosan.de\/de\/mediathek\/fuer-kunden\"\u003emedia library\u003c\/a\u003e. \u003cbr\u003e\u003cbr\u003eContents and storage:\u003cbr\u003eCartridges with 50 test discs each.\u003cbr\u003eStore at 2-8° C.\u003cbr\u003e\u003cbr\u003eNote: Cartridges of the BD system are only compatible with BD dispensers (Becton Dickinson).\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003cp\u003eAs an alternative to agar diffusion, we recommend agar dilution, which can be partially automated, for example with the \u003ca href=\"https:\/\/aurosan.de\/images\/mediathek\/produktinformationen-urologie-gynaekologie\/MICRONAUT-Produktinformationen.pdf\"\u003eMICRONAUT system\u003c\/a\u003e, and for which there are increasingly more and more precise clinical breakpoints, i.e. since EUCAST 10.0 (2020) at the latest, certain antibiotics can only be tested using agar dilution, and no longer using agar diffusion (!).
