A wide variety of stains are useful for detection of different organisms
or, for viruses, the cytopathologic changes they induce, in smears prepared
directly from clinical specimens and in tissue sections. Other types of
stains, such as hematoxylin and eosin, are used routinely to stain tissue
sections and are most valuable for assessing the immunologic response of
the host to the invading pathogen. In many cases, the pattern of
inflammation provides important clues to diagnosis and helps to guide the
selection of additional "special" stains used predominantly for diagnosis
of infectious diseases. A stain may be nonspecific, allowing detection of a
spectrum of organisms, as do the Papanicolaou stain and silver impregnation
methods, or detection of only a limited group of organisms, as do the
different acid-fast techniques. Some nonspecific stains, such as the Gram
stain, are differential and provide valuable preliminary information
concerning identification. Immunohistochemical stains, on the other hand,
are specific for a particular organism, although in some cases
cross-reactions with other organisms occur. Despite the wealth of
information that can be gleaned from a stained smear or section of tissue,
however, the specific etiology of an infection often cannot be determined
on the basis of only the morphology of the organisms seen; culture data are
essential and must be considered in the final diagnosis.
