    • A method of determining the number of bacteria in a sample which involves introducing a sample containing bacteria into a tubular filtering vessel holding therein a hydrophobic filter for bacterial detection, a coloring composition is disposed on the side of the filter where the sample is introduced into the vessel, and a support for the filter is disposed on the opposite side of the filter from the coloring composition. The bacteria is subjected to and the sample is filtered dyeing sample by suction from the support to collect the dyed bacteria on the filter and remove the excess of coloring matter. The number of the bacteria in the sample is determined from the degree of staining of the filter.

    • A method for detecting an analyte in a sample uses both the specificity of an enzymatic reaction and the separation power of capillary electrophoresis. In general, the method comprises: (1) subjecting a first aliquot of the sample to an analytical technique such as capillary electrophoresis, which generates a first output such as an electropherogram; (2) reacting a second aliquot of the sample in an enzyme-catalyzed reaction converting the analyte into a product, the product being detectable by the analytical technique; (3) subjecting the second aliquot to the analytical technique to generate a second output; (4) in the case of electrophoresis, measuring the absorbance of the first and second outputs (electropherograms) as a function of migration distance along the electropherogram at at least one wavelength at which either the analyte or the product absorbs to produce a first absorbance scan and a second absorbance scan; and (5) comparing the first absorbance scan with the second absorbance scan to detect the analyte. The reaction can involve a coenzyme and the analytical technique can be directed to the coenzyme. Alternatively, at least two enzymes can be used, the first enzyme generating a first product that is then acted upon by the second enzyme.

    • A method, reagent mixture and test kit are provided for testing a urine sample for the presence of bacterial or somatic cells, by reacting a urine sample with a catalase-free alkaline protease enzyme and a detergent compatible therewith, so as to disrupt any such cells present in the sample and release active catalase therefrom. The presence of catalase is detected by the formation of foam upon the addition of H.sub.2 O.sub.2. The reaction of the sample with the protease enzyme and the detergent is conducted in the presence of: (a) a buffer providing for a pH of about 8.5 to about 9; and optionally (b) one or more additional solutes; the total concentration of components (a) and (b), when present, being from about 0.02M to about 0.4M.
