Abstract: Method and assay devices for the detection of the presence or amount of biological material, analyte(s), or microorganism(s) in a sample. The method includes the steps of liquefying the sample (if necessary) and distributing the liquefied sample over the surface of the assay device. The device may comprise an incubation plate, a dip stick device, or other devices. The devices have at least one reagent provided within the devices. Some devices have a generally flat horizontal surface which is divided into a plurality of recessed wells. Others have one or more surfaces with reagent island(s) immobilized thereon. Each well or reagent island is adapted to hold an aliquot of liquid. The wells or reagent islands are sized and shaped, and formed of a suitable material, to hold the aliquot within the well or reagent island by surface tension. Any excess liquid from the liquefied sample is drained from the surface of the device. The method then involves incubating the assay device until the presence or amount of the biological material, analyte, or microorganism is determined.

Abstract: A multicompartment assay device comprising at least one compartment comprising a viable organism control medium capable of sustaining growth of total microbial organisms; at least one compartment comprising a medium capable of selectively sustaining growth of target microbial organisms; and, at least one compartment comprising an antimicrobial susceptibility interpretation medium. Also, a method of detecting the presence of target microbial microorganisms in a biological sample and of simultaneously determining the susceptibility of such microorganisms to antimicrobial agents by use of such a device.

Abstract: Disclosed is a medium for growing Enterococci so that detection may be obtained within 24 hours. It contains one or more nutrient indicators, selective agents to inhibit the growth of other microorganisms, and vitamins, amino acids, trace elements and salts. More specifically, the medium contains a) an effective amount of vitamins, amino acids, trace elements and salts operable to allow viability and reproduction of Enterococci; b) an effective amount of one or more nutrient indicators provided in an amount sufficient to provide a detectable characteristic signal in the medium during growth of said Enterococci; said nutrient indicator releasing a nutrient moiety in the presence of a-glucosidase; c) an effective amount of one or more selective agents active to prevent or inhibit the growth of microorganisms other than Enterococci.
