A method and compound for detecting low levels of microorganisms in biological samples is disclosed. In the method, an antibiotic is conjugated to a detectable label. This antibiotic/label conjugate is then introduced into a sample containing biological material. The antibiotic binds to target microorganism where the label allows for detection of localized concentrations of the antibiotic. A compound to accomplish this method is also described. This compound is an antibiotic conjugated to a fluorescent dye. This dye has an excitation and emission wavelength that are not interfered by substances typically found in biological samples.
