Abstract
The present invention encompasses a method for enumerating microbial cells in an aqueous test sample comprising: fluorescently labeling the microbial cells in test sample intermixing a known amount of monodispersed fluorescently labeled beads of about cell size into the test sample, and determining the ratio of bacterial cells to fluorescently labeled beads, the reagents for practicing this method. The methods and reagents of the present invention are particularly useful in counting bacterial cells in urine.
Claims2
A method for enumerating bacterial cells in urine comprising adding to a urine sample an effective bacterial cell labeling amount of fluorescent dye and a known number per ml of urine of monodispersed fluorescently labeled beads of about cell size and determining the ratio of fluorescently labeled bacterial cells to fluorescently labeled beads.
