Guarnieri bodies

From Wikipedia, the free encyclopedia

Guarnieri bodies ({{{1}}}: /gwaɹ.ˈɲjeː.ˌɹi/) are found upon microscopic inspection of epithelial cells of individuals suspected of having smallpox and other vaccinia virus infections. They are pink blobs that appear in the cytoplasm of affected epithelial cells and represent aggregates of the virus. The absence of Guarnieri bodies cannot be used as to rule out smallpox, however, as more sensitive test need to be performed. They are named after the Italian Physician Guiseppi Guarnieri.
