Abstract

Described herein are methods and reagents for identifying and analyzing at least one microorganism (e.g. bacteria) in a sample and reducing the background signal intensity obtained when analyzing the sample by flow cytometry. The sample is prepared by combining the sample with a background signal reducing molecule or with a nucleic acid stain covalently linked to a quencher. A portion of the particulate matter in the sample can optionally be removed with a resin prior to staining with a nucleic acid stain.
