B-type inclusions, formerly known as Guarnieri bodies / ɡ w ɑːr n ˈ j ɛər i / are cellular features found upon microscopic inspection of epithelial cells of individuals suspected of having poxvirus [1] (e.g. smallpox [2] or vaccinia). In cells stained with eosin, they appear as pink blobs in the cytoplasm of affected epithelial cells.
Morphologically there are two types of Orthopoxvirus inclusion bodies, Type-A inclusion bodies and Guarnieri bodies. Type-A inclusion bodies are found only in certain poxviruses like cowpox . [ 3 ] The Guarnieri bodies are found in all poxvirus infections and their presence is diagnostic. [ 4 ]
Inclusion bodies have a non-unit (single) lipid membrane [citation needed].Protein inclusion bodies are classically thought to contain misfolded protein.However, this has been contested, as green fluorescent protein will sometimes fluoresce in inclusion bodies, which indicates some resemblance of the native structure and researchers have recovered folded protein from inclusion bodies.
Giuseppe Guarnieri (April 20, 1856 – August 15, 1918) [1] was an Italian physician. Dr. Guarnieri made his most famous discovery in 1892 while examining thin tissue cells damaged by smallpox. He discovered small bodies of protein clusters that he mistook for bacteria , but were actually clusters of viral proteins crucial in the replication of ...

The Guarneri (/ ɡ w ɑːr ˈ n ɛər i /, [1] [2] UK also /-ˈ n ɪər-/, [3] Italian: [ɡwarˈnɛːri]), often referred to in the Latinized form Guarnerius, is the family name of a group of distinguished luthiers from Cremona in Italy in the 17th and 18th centuries, whose standing is considered comparable to those of the Amati and Stradivari families.
