=Introduction=
 
 
 
 
 
=Morphology=
 
*Large, spherical enveloped RNA viruses
 
*Identified by their '''crowns''': long bulbous widely-spaced spikes
 
 
 
=Virulence and Pathogenesis=
 
*Pathogenesis varies widely based on each virus, but most commonly cause '''respiratory''' and '''enteric''' disturbances
 
*Those described here will be the enteric variety
 
 
 
=Virus by Species=
 
===[[Transmissible Gastroenteritis Virus of Pigs (TGEV)]]===
 
===[[Bovine Enteric Coronavirus]]===
 
===[[Feline Infections Peritonitis (FIP)]]===
 
 
 
 
 
* Coronavirus contributes to [[Intestines Catarrhal Enteritis - Pathology#Undifferentiated Neonatal Calf Diarrhoea|undifferentiated neonatal calf diarrhoea]], a mixed viral enteritis in calves.
 
* [[Intestines Catarrhal Enteritis - Pathology#Transmissible Gastro-Enteritis (TGE)|Transmissible Gastro-Enteritis (TGE)]] in pigs
 
* [[Intestines Catarrhal Enteritis - Pathology#Winter Dysentery|Winter dysentery]] in cattle.
 
* [[Intestines Granulomatous Enteritis - Pathology#Feline Infectious Peritonitis|Feline Infectious Peritonitis]].
 
*Calf coronavirus may contribute to [[Respiratory Bacterial Infections - Pathology#Enzootic pneumonia of calves|Enzootic pneumonia of calves]]
 
*Porcine respiratory coronavirus (PRCV) in pig [[Respiratory Viral Infections - Pathology#Porcine respiratory coronavirus (PRCV)|pneumonia]]
 
*Porcine encephalomyelitis, apart from neuronal destruction, may also cause [[Muscles Inflammatory - Pathology#Porcine encephalomyelitis|myofibre necrosis]]
