B-type inclusions formerly known as Guarnieri bodies /ɡwɑrˈnjɛri/ are cellular features found upon microscopic inspection of epithelial cells of individuals suspected of having poxvirus (e.g. smallpox or vaccinia). In cells stained with eosin they appear as pink blobs in the cytoplasm of affected epithelial cells. The absence of Guarnieri bodies cannot be used as to rule out smallpox however as more sensitive test need to be performed.
