How do you treat CL in sheep?
- There is not an effective treatment for CL.
- Avoid purchasing animals with visible abscesses or abscess scars.
- Avoid giving injections in the shoulder region where an injection-site reaction can be confused with a CL abscess.
What causes CL in sheep?
Ca seous lymphadenitis (CL) is a chronic infection of sheep and goats caused by Cornebacterium pseudotuberculosis bacteria. This contagious disease is best known for abscesses (buildup of pus) in the external lymph nodes of the neck and abdomen.
How do you control Caseous lymphadenitis in sheep?
Treatment and Control
- Strict biosecurity measures.
- Elimination of diseased animals from the herd/flock.
- Vaccination.
- Disinfection of shearing equipment and other instruments used for production procedures (castration, ear tagging, etc) between animals.
What kills caseous lymphadenitis?
Despite reported success with various antimicrobial regimens coupled with strict biosecurity measures, eliminating affected animals from the herd or flock remains the best way to eliminate caseous lymphadenitis.
Is there a vaccine for CL in sheep?
There are commercial CL vaccines available for sheep and goats. The vaccine may help reduce the prevalence of CL within a flock but will not prevent all new infections or cure existing infections. Consult a veterinarian to discuss vaccine usage in your flock, especially before using the vaccine in a naïve flock.
Should you cull a goat with CL?
When working around goats with CL, isolate any with developing abscesses away from the rest of herd. If the abscesses recur you should consider culling the animals to prevent infecting the rest of the herd. You may also want to vaccinate the rest of the herd to prevent infection.
Can humans get caseous lymphadenitis?
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. CL is caused by Corynebacterium pseudotuberculosis. While its prevalence varies by region, CL is found worldwide.
How long does CL live underground?
If an abscess ruptures in a pasture, the organic material (soil, grass) is contaminated, and the pasture should be rested for a prolonged period of time; CL has been shown to survive in soil for 8 months.
Can humans get CL?
What is CL testing for sheep?
Testing for Caseous Lymphadenitis (CL, occasionally abbreviated CLA) is recommended as part of the small ruminant herd biosecurity screen offered through the Washington Animal Disease Diagnostic Laboratory (WADDL) at Washington State University. This infection is a potential health threat to sheep or goat herds.
How do you manage Clostridium infections in sheep?
However, certain management practices can help to minimize the impact of CL on the herd or flock. Conduct frequent visual examinations of the herd and note the presence of abscesses. This may require a closer inspection in wool sheep and fiber goat breeds where long course hair or wool can hide abscesses.
What kind of lymphadenitis does a sheep have?
Caseous Lymphadenitis of Sheep and Goats. Caseous lymphadenitis (CL) is a chronic, contagious bacterial disease that manifests clinically as abscesses of peripheral and/or internal lymph nodes and organs.
Should I worry about CLCL in my sheep or goat?
CL should be highly suspected in a sheep or goat with abscessation in these regions. Although other bacteria may cause abscessation in these locations (and in other animals), because of the ramifications of the presence of this disease within a herd or flock, these cases should be handled as CL until proved otherwise.
