Zibeyda Gambarova | MD on Instagram: "The disk diffusion method is a standard technique for determining bacterial antibiotic susceptibility. Antibiotic-impregnated discs are placed on an agar plate inoculated with the bacterial culture. As the antibiotics diffuse, a zone of inhibition forms around the disc, allowing the effectiveness of the antibiotic in inhibiting bacterial growth to be assessed. This method is simple, accessible, and frequently used to select optimal antibiotic therapy."
