    Abstract: A method of determining the presence or absence of a nonparaffinophilic microorganism in a specimen taken from a patient includes providing a receptacle containing an aqueous solution that does not contain a carbon source and inoculating the aqueous solution with the specimen. A slide having bound thereto a carbon source is placed into the receptacle. By analyzing the slide after exposure to the specimen, the presence or absence of a nonparaffinophilic microorganism in the specimen can be determined. An associated apparatus is also disclosed.

    Abstract: There is disclosed an improved method for testing for the presence of a particular microorganism or group of microorganisms characterized by a particular enzyme. The method uses a dye-forming substrate throughout a polymer matrix or on the surface of a solid support member that forms a colored precipitate when cleaved by the enzyme. The precipitate is concentrated to the polymer matrix and/or solid support member to create a visible reaction product, wherein the amount of dye-forming substrate needed is independent of the sample size. The present invention further comprises an enzyme indicator device comprising a dye-forming substrate throughout a polymer system or on the surface of a solid support member.

    Abstract: The invention provides a technology for promptly determining bacterial identification or an antimicrobial susceptibility testing. In the invention, first, a state where the bacteria are divided is monitored by performing microscopic observation with respect to the shape or the number of bacteria in each of wells of a culture plate for bacterial identification culture or the antimicrobial susceptibility testing. In addition, the shape, the number or the area of the bacteria are interpreted from the image obtained by the microscopic observation whether or not the bacteria proliferate at a stage from an induction phase to a logarithmic phase, and the time-dependent changes thereof are made into a graph. From the graph, it is determined whether or not the bacteria proliferate for each measurement, the determination results are displayed on the screen, and accordingly, the result of the antimicrobial susceptibility is provided every time when the measurement is performed.
