Introduction

Coronaviruses are perhaps most easily identified because of their classic "crown" appearance. They are quite common in the young of most species and can infect a wide range of tissues.

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)

• Porcine respiratory coronavirus (PRCV) in pig pneumonia
• Porcine encephalomyelitis, apart from neuronal destruction, may also cause myofibre necrosis
