This is a disease associated with ''Fusobacterium necrophorum'', which is a strict anaerobic bacteria found everywhere in the environment. The disease is usually trasmitted by oral ingestion of the bacteria. It is often a secondary invader, meaning prior tissue damage must have to occur for the bacteria to gain entry, however it can be a primary pathogen in some cases. There are two forms of calf diptheria; oral and laryngeal.

'''Oral form''' - common yet sporadic in occurrence and is often associated with poor hygiene especially in housed calves that are bucket fed, although it can occur in calves at pasture. Calves are usually less than three months old and the disease is often predisposed to by teeth eruption, rough feed, poor use of dosing gun or presence of a concurrent disease.
