    Abstract: This invention provides an imaging system for high-accuracy quantitative analysis of a microarray. In certain embodiments, the system comprises a broad band excitation light source that provides Kohler illumination of said microarray at an incident angle that ranges from about 30 degrees to about 75 degrees from the normal to the microarray, and that has less than about ± 25 percent variation in intensity over the array at all wavelengths ranging from 400 to 800 nm; a support for holding a microarray; a detection lens system that is chromatically corrected so the apparent position of the microarray or a feature comprising the microarray varies by less than 10 µm as the detection wavelength varies from about 400 to about 800 nm; and a detection device for detecting and optionally recording an image produced by said detection lens system.

    Abstract: This invention provides novel methods for detecting microorganisms is biological samples. The methods utilize in situ hybridization techniques. In one preferred embodiment, the methods involve blocking binding of nucleic acid probe(s) to granulocytes. The method typically involves contacting a biological sample with a nucleic acid probe that specifically hybridizes under stringent conditions to a nucleic acid of a microorganism and a blocking reagent that is a non-coding nucleic acid, washing the biological sample to remove probe that is not hybridized to a nucleic acid of the microorganism, and detecting the probe where the presence of remaining probe indicates the presence of the microorganism.
