Plastic embedding is a recently developed technique that has been shown to be superior to conventional paraffin embedding in the histopathologic identification of microorganisms in tissue specimens. This report describes a modification of the Brown and Hopps stain for the differentiation of gram-positive and gram-negative microorganisms in 3-micron-thick plastic sections. This technique is easily performed and has a rapid turnaround time. This staining method permits a more precise histopathologic diagnosis of infectious agents than is possible in paraffin-embedded tissues.
