Aphthovirus

Aphthovirus (from the Greek aphtha-, vesicles in the mouth) is a viral genus of the family Picornaviridae.

After genome replication within the cytoplasm, virion assembly occurs and new virus particles aggregate within the cell.

[6] Aphthoviruses include the causative agents of foot-and-mouth disease (FMD), which primarily affects livestock such as cattle, swine, sheep and goats.

Endemic regions of the disease include areas of Africa, Asia and South America.

[1] Equine rhinitis A virus (ERAV) was first isolated from horses in the 1960s and 1970s showing acute febrile respiratory disease signs, including fever, cough, clear nasal discharge and lethargy.

Modern molecular biology techniques such as nucleotide sequencing demonstrated that ERAV was in fact more closely related to FMDV, and was reclassified to the genus Aphthovirus.
