Multodiscs with eight antibiotics

MULTODISCS are rings of absorbent paper with eight arms, each terminating in a 6 mm disc impregnated with an antibiotic. Each disc is marked with an identification code. A barrier of inert material at the end of each arm prevents diffusion of the antibiotic. This makes it possible to have easily measurable circular inhibition zones and makes MULTODISCS suitable for sensitivity tests using Kirby-Bauer method (KB testing or disk diffusion antibiotic sensitivity testing). MULTODISCS are offered in a large variety of configurations.

The discs are applied to the surface of a culture medium inoculated with the broth culture containing pure colonies of the microorganism under examination. After incubation, the plates are examined, the inhibition halos around each disc are examined and compared with the standard inhibition haloes: in this way the microorganisms are defined as being susceptible, intermediate or resistant to the tested antimicrobial agents.
