The absence of Guarnieri bodies cannot be used as to rule out smallpox, however, as more sensitive test need to be performed. B-type inclusions are the sites of viral replication and are found in all poxvirus-infected cells, unlike A-type inclusions which are more strongly eosinophilic and only found in infections with certain poxviruses.

Inclusion body myositis (IBM) (/ m aɪ oʊ ˈ s aɪ t ɪ s /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [2] The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso ) and distal muscles (close ...
Cytomegalic inclusion body disease (CIBD) also known as cytomegalic inclusion disease (CID) is a series of signs and symptoms caused by cytomegalovirus infection, toxoplasmosis or other rare infections such as herpes or rubella viruses. It can produce massive calcification of the central nervous system, and often the kidneys. [1]
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.
The Guarnieri bodies are found in all poxvirus infections and their presence is diagnostic. [4] The diagnosis of an orthopoxvirus infection can also be made rapidly by electron microscopic examination of pustular fluid or scabs. However, all orthopoxviruses exhibit identical brick-shaped virions by electron microscopy. [citation needed ...

The inclusion bodies can first be identified by light microscopy in patient blood smears or stained sections of infected tissues. However, to fully characterize their composition, electron microscopy must be performed. Inclusion bodies may either be accumulation of virus replication byproducts or altered host cell organelles or structures. [3]
Histological slide of the human herpes virus-6 showing infected cells, with inclusion bodies in both the nucleus and the cytoplasm. Inclusion bodies were first described in the late 19th and 20th centuries. One of the earliest figures associated with the discovery of inclusion bodies is Fritz Heinrich Jakob Lewy.
