| − | =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]]
