Abscess disease, caseous lymphadenitis, and pulmonary adenomatosis in imported sheep

The occurrence of abscess disease, caseous lymphadenitis, and pulmonary ade nomatosis in sheep in Denmark is reported for the first time. Subcutaneous abscesses were observed in imported 4- to 5-month-old lambs of the Lacaune breed 10 days after arrival in Denmark. Abscesses were mostly located in th e head, neck and shoulder regions close to the regional lymph nodes. Bacter iological examinations revealed growth of Staphylococcus aureus ssp. anaero bius in all animals with subcutaneously located abscesses containing a visc ous white-yellow odourless mass. In addition, Corynebacterium pseudotubercu losis was isolated from abscesses in one animal and lesions consistent with pulmonary adenomatosis were found in four animals.
