 ===[[Bovine Virus Diarrhoea Virus]]===
-*'''Mucosal Disease''': erosive condition produces small multiple, cleanly punched out lesion in mouth
-*[[Neutrophils - WikiBlood|Neutrophils]] invade the ulcer and if bacterial colonisation occurs, further excavation follows. Either:
-::#This lesion develops a granular base and becomes diphtheritic.
-::#If bacterial colonisation does not take place, healing occurs within fourteen days.
-*Seen in most parts of mouth (or maybe on muzzle) e.g. dental pad, [[Cheeks - Anatomy & Physiology|cheeks]], sides of [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]]
-*Lesions extend throughout gut with particularly big ulcers in small intestine over [[Peyer's Patches - Anatomy & Physiology|Peyers patches]]. Necrosis occurs in lymph nodes and [[Spleen - Anatomy & Physiology|spleen]]

-*No vesicular stage, prickle cells die off from surface resulting in layer of necrotic debris over epithelial layer
-*Infection penetrates inward through stratum germinativum.
-*Epithelium does not recover as animal does not recover
