Aphthovirus (from the Greek aphtha-, vesicles in the mouth) is a viral genus of the family Picornaviridae. Aphthovirsues infect vertebrates, and are the causative agent of foot-and-mouth disease. There are seven Aphthovirus serotype: A, O, C, SAT1, SAT2, SAT3 and Asia1. Viruses can be classified in several ways, such as by their geometry, by whether they have envelopes, by the identity of the host organism they can infect, by mode of transmission, or by the type of disease they cause. ...
