Because this product is conditionally licensed, the vaccine is regulated by each states veterinary agency. Isolates from cattle are a heterogeneous group.

They should remain isolated from the rest of the herd or flock until their serologic status is determined, and only animals that are seronegative with no evidence of present or past CL lesions should be allowed to enter the herd or flock. However, animals with draining abscesses should not be sent through sale barns until draining has ceased and the wound has healed. We suspect this is due to pandemic-related staffing and material shortages. Although other pyogenic organisms such as Trueperella pyogenes (formerly Arcanobacterium pyogenes), Staphylococcus aureus, Pasteurella multocida, and anaerobes such as Fusobacterium necrophorum can cause abscessation, affected animals should be kept isolated pending culture results. Any replacement animals should be tested and isolated for a period of two to three months prior to introduction to the rest of the herd. When acquiring new animals, testing the herd of origin (10 or more animals) is the preferred approach to determining the status of the new additions. False-negative results can occur if testing is done in the first 2 weeks after exposure before the animal has seroconverted. The most common site of entry is the skin after an injury that may result from shearing, tagging, tail docking, castration, or other environmental hazards resulting in skin trauma.

Caseous lymphadenitis (CL) is a chronic, contagious disease caused by the bacterium Corynebacterium pseudotuberculosis. No CL serological test is sufficiently reliable to confidently detect infection in individual sheep or goats, therefore the serology results for an individual animal test should be interpreted with caution. Caseous lymphadenitis (CL) is a bacterial infection found mostly in sheep and goats, though other species such as horses, cows, camelids, pigs, fowl and people can be infected. To report clinical and laboratory features, treatment responses and outcome in dogs diagnosed with sterile steroid-responsive lymphadenitis in the United Kingdom. Design Randomized clinical trial. Veterinary reviewed by: Dr. Linda Simon, MVB MRCVS. Many environmental bacteria can cause abscesses via traumatic wounds, but unlike CL these are sporadic and not readily transmitted from animal to animal.

Although prevalence of CL varies by region and country, it is found worldwide and is of major concern for small ruminant producers in North America. Radiography and ultrasonography can be useful to detect internal lesions. CL should be highly suspected in a sheep or goat with abscessation in these regions.
