Abstract: An antimicrobial susceptibility assay enabling a more rapid and direct result, including an assay dish including at least one chamber, at least one growth medium carried by the assay dish, at least one antimicrobial agent sample positionable at a sample location adjacent a growth medium in the assay dish, at least one interpretive indication positionable at a predetermined distance from the sample location adjacent a growth medium in the assay dish, and at least one interfitting element, said at least one interfitting element configured cooperate with the assay dish to enable at least one of: a) more accurately positioning said at least one antimicrobial sample at the sample position in contact with the growth medium; b) carrying said at least one interpretive indication positionable at a predetermined distance from said sample position; said assay enabling the interpretative indication to be visually compared with a margin of a zone of inhibition of microbial organism growth on said growth medium to determin

Abstract: An antimicrobial susceptibility assay, including the steps of: providing an assay dish; providing a growth medium in said dish; providing an antimicrobial agent sample; providing an interpretive indication located a predetermined distance from a sample location adjacent the growth medium in the assay dish; providing an interfitting element which interfits with said dish, said interfitting element configured to enable at least one the steps of: a) more accurately positioning the antimicrobial sample at the sample location in contact with the growth medium; b) providing the interpretive indication at a predetermined distance from said sample position to enable said interpretative indication to be compared with a margin of a zone of inhibition of a colony grown on said medium to determine an assay result, wherein said result can include determination of at least one of: a) “susceptible;” “intermediate;” and, “resistant;” placing a microorganism on the growth medium; placing the antimicrobial agent sample at said

Abstract: A Method and Kit for performing concurrent identification testing and antimicrobial susceptibility testing from broth culture (90) are described. Broth (82) incubation is generally 4 to 6 hrs providing adequate numbers of microorganisms for inoculating a multi-chambered plate (80) comprising enriched, differential, selective, differential-selective, single-purpose and susceptibility media. Several dilutions are prepared from the cultured broth, for inoculation of the kit plate (80). The more dilute concentration (140) produces individual colonies of microorganisms, for identification testing. This isolation makes an initial isolation step unnecessary. The heavier concentration dilution (96) provides inoculation for antimicrobial susceptibility tests and other identification tests. In addition, antimicrobial susceptibilities are shown valid even when several different microorganisms coexist in the same test chamber. The method is fast for bacteria, providing identification and susceptibility data in 24 hrs.
