Caseous lymphadenitis (CL, occasionally abbreviated CLA) is a bacterial infection caused byCorynebacterium pseudotuberculosisresulting in superficial or internal abscesses and recurrent development of abscesses. We recommend centrifugation of the blood sample, separation of the serum into a sterile twist-top tube, and storage at refrigeration temperature prior to shipping for best results. 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. Epub 2018 Oct 4. Some of the organisms that cause lymphadenitis are zoonotic (can be communicated to humans and other species). The Merck Veterinary Manual was first published in 1955 as a service to the community. A fine needle aspirate, or needle core, partial, or excisional biopsy may be done for further investigation into the inflammatory origin. Zoonoses Public Health. Caseous lymphadenitis is currently of most interest in small ruminants and is implicated as the third leading cause of economic loss to the sheep industry in the western United States. The practice of injecting abscesses with formalin should be strongly discouraged, because the FDA has zero tolerance for extra-label use of a potent carcinogen in food-producing animals. The presence of organic material, shade, and moisture favor and enhance survival. Young dogs (median age: 3 years and 9 months) and females (31 of 49) were frequently affected. The serology test is best used as a screen to find out if a herd or flock has been infected, rather than to diagnose an individual animal with CL.

When the status of an animal with a positive titer is in doubt, the titer should be repeated in 24 weeks. Your veterinarian will order a complete blood count and serum biochemistry, to look for specific markers that may point to illness or infection (hypercalcemia and hyperglobulinemia are common with lymph node inflammation). Once an animal or herd has been diagnosed with CL, strict biosecurity is the most important means of containing the disease. In older sheep, the probability of the presence of purulent or caseous lymphadenitis was higher than in younger, and the risk was increasing by 1.5% with each month of life. 2020 Feb;31(3-4):253-267. doi: 10.1089/hum.2019.297.

It must be noted here that the use of any antimicrobial for treatment of CL is extra-label; therefore, strict adherence to published guidelines on withdrawal times and an established veterinarian-client-patient relationship are mandatory. Saturdays (limited service): 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.

Although less common, entry across mucous membranes from inhalation or ingestion of the bacteria also serves as a means of infection. Titers of 1:256 or higher have been correlated in past studies with the presence of active, developing abscesses; however, in a more recent study, a high titer was poorly correlated with presence or development of abscesses over an 18-month period. Pack so the box can be dropped from a 4-foot height without breaking any tubes. Though there have been documented cases of CL transmission to people from infected goats and sheep, the incidence is rare. 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. Frequency of screening should be based on the prevalence within the herd (from previous herd tests) and the risk of outside exposure (level of biosecurity for new animals entering the herd, and animals attending outside events). The vaccine will not clear CL from infected animals and is not recommended for use in herds that have not previously been diagnosed with CL.

Remove potential hazards like sharp wire to minimize injuries and keep the environment free of moisture and organic debris. We recommend working with your veterinarian on the pros and cons of vaccination for CL. Abnormalities and swelling of the lymph node can result in symptoms that will alert you to the fact that there is an ongoing disease present. 1 In 1 report 2 in which investigators examined samples from culled sheep from regions representing 9 western states, the prevalence was estimated as 42.41%.

Excluding other causes of chronic weight loss and ill thrift in the face of proper nutrition and good appetite such as Johnes disease, parasitism, and poor dentition further raise suspicion. Immunosuppressive treatment appears to be effective, and relapse is uncommon with appropriate immunosuppressive treatment.

In situations where elimination of affected animals is not desirable, dividing "clean" and "infected" animals into separate herds/flocks, prompt antimicrobial treatment, isolation of animals with active lesions, and culling of aged infected animals may eventually lead to decreased prevalence of CL. Also, it may be difficult to distinguish on the basis of clinical findings from other causes of lymph gland enlargement, or a proliferation of cells in the lymph nodes for some other reason, such as cancer.
