Other complications will depend on the location of the infection and whether it is affecting surrounding organs. Penicillin alone, although effective in vitro, is unlikely to penetrate the capsule of developed abscesses, as are many, if not most, of the water-soluble or moderately lipid-soluble antimicrobials. After the affected animals have been culled, disinfect any contaminated troughs, water buckets and structures with chlorhexidine or bleach. Pack the container or tubes in a plastic sealable bag with absorbent material and put another plastic bag around the first. If a herd or flock is vaccinated, then serologic screening is no longer a useful method for detecting natural infection, and therefore as vaccinated herds may test positive on the blood test (serology). Email: diagcenter@cornell.edu, Business Hours 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. Animals with visceral abscesses pose a greater diagnostic challenge. All strains produce an exotoxin called phospholipase D that enhances dissemination of the bacteria by damaging endothelial cells and increasing vascular permeability. Oops! The prevalence of caseous lymphadenitis in these stud herds was a cause of economic loss to the owners through euthanasia of severely affected goats, reduced milk production and emaciation, the cost of labour and drugs for treatment, jeopardisation of income from boarding or mating with outside stock and the appearance of goats at stud shows, and Bartonella vinsonii infection may cause granulomatous (nodular) lymphadenitis in dogs Fungi Infections commonly include lymphadenitis as one manifestation of a systemic disease Likely organisms include Blastomyces, Cryptococcus, Histoplasma, Coccidiodes, Sporothrix Other fungal agents have occasionally been reported Viruses Please contact our Veterinary Support Services team with additional questions by calling 607.253.3900 or emailing vetsupport@cornell.edu.

The epidemiology of caseous lymphadenitis in Australia and observations on other production systems. Part of the diagnosis of the lymph node inflammation will involve checking carefully for underlying disease processes. The internal form of CL is more common in sheep.

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. Although many diagnostic tools are available, results of these tests must be interpreted with caution and with consideration of herd or flock history, the presence or absence of active infection within the herd or flock, and vaccination status. We have taken some of the most frequently asked questions and presented them along with some short answers. Contact with purulent material draining from open, active lesions most commonly serves as the source of bacteria through these breaches in the skin.

For serology, blood should be collected into a 5 or 10 ml red-top clot tube or serum separator tube. 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. Dividing the herds or flocks into clean and infected groups and eliminating older and less genetically valuable animals over time is one control strategy. The frequency for testing an established herd or flock should be based on previous test results, eradication strategies, and the risk of exposure to other herds or flocks. It is possible for infected animals with active abscesses to test negative on serology due to a delay in antibody production (there is a delay inantibody production after initial infection).
