The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility ...
Mueller Hinton agar is commonly used in the disk diffusion method, which is a simple and widely used method for testing the susceptibility of bacterial isolates to antibiotics. In this method, small disks impregnated with different antibiotics are placed on the surface of the agar, and the zone of inhibition around each disk is measured to ...
A double-disk diffusion test is a kind of disk diffusion test (to test for the effectiveness of an antimicrobial agent a disk infused with it is placed on a cultivated agar dish of bacteria to see if the antimicrobial agent in the disk inhibits further growth of the bacteria. [1])
The "gutter method" that he developed was a diffusion method, involving an antibiotic that was diffused through a gutter made of agar. [25] In the 1940s, multiple investigators, including Pope, Foster and Woodruff, Vincent and Vincent used paper discs instead. [25] All these methods involve testing only susceptibility to penicillin.

RID often produces a similar plot while all precipitin circles are expanding, as in the kinetic method (see [11] and [12]). One can determine the antigen concentration in a sample whose concentration is unknown by finding its location on a graph that charts the diameters of precipitin circles produced by three or more reference samples with ...
Immunodiffusion is a laboratory technique used to detect and quantify antigens and antibodies by observing their interactions within a gel medium. [1] This technique involves the diffusion of antigens and antibodies through a gel, usually agar, resulting in the formation of a visible precipitate when they interact.
In this particular research, the potential anti-fungal agent was subjected to both disk diffusion test and the micro-atmosphere method for comparison and to get an idea of how the active compound may be utilized. The active compound exhibited higher anti-fungal effects in the disc diffusion test compared to the micro-atmosphere assays.
Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
