Caseous Lymphadenitis Outbreak in Dairy Cattle: Clinical Findings, Management, and Autogenous Vaccine Development

Share:
Costa et al. presented: “This case report describes an outbreak of caseous lymphadenitis (CL) in a dairy herd of 500 Friesian cows in Évora, southern Portugal—an unusual event, as CL typically affects small ruminants. Fifty-five cows (11%) developed swelling of lymph nodes, weight loss, fever, and reduced milk production, with lesions most frequently observed around the head.”
