Blood titers are available but can be difficult to interpret as they cannot differentiate between past infection, recent exposure or vaccination and active disease. Although we will test samples mailed directly from an owner, we strongly encourage animal owners to work with a veterinarian in developing a CL control program. If the titer is rising and clinical signs of abscesses are noted, then CL can be assumed to be the cause.

The internal form is more common in sheep and has been termed the thin ewe syndrome.. The organism may remain viable for months in the environment, and fomites also spread disease. Two biotypes have been identified based on the ability of the bacteria to reduce nitrate: a nitrate-negative group that infects sheep and goats, and a nitrate-positive group that infects horses.
