==Introduction==
==Morphology==
*Very small RNA viruses
*Much antigenic variation
*Subtypes evolve and do not cross-protect
*4 capsid proteins (VP1-VP4), with VP1 providing neutralizing target
==Virulence and Pathogenesis==
*Cytopathic effect of all viruses is an overnight '''cell rounding''' and '''pyknosis'''
==Epidemiology==
*Very resistant
*Can survive several months on '''fomites'''
*Infect via upper respiratory tract or buccal cavity and spread to target organs after viremia
==Types and Subtypes==
3 Main Genera:
===Enteroviruses===
*[[Swine Vesicular Disease]]
*[[Porcine Enterovirus]]
===Apthoviruses===
*[[Foot and Mouth Disease (FMDV)]]
===Rhinoviruses===
*Subclinical cold viruses
*Equine rhinovirus (picornavirus type 1 and 2) in [[Nasal Cavity Inflammatory - Pathology#Infectious causes of rhinitis|rhinitis]], see [[Respiratory Viral Infections - Pathology#Equine rhinovirus|respiratory infections]]
*Bovine rhinovirus may cause mild [[Respiratory Viral Infections - Pathology#Bovine rhinovirus|respiratory infections]]
