Abstract

Johne's disease, or paratuberculosis, in cattle, caused by Mycobacterium avium subspecies paratuberculosis (MAP), can cause substantial economic losses on dairy farms. This case study describes the finding of a MAP prevalence of 8% in a Dutch dairy herd with a 10-year history of biennial enzyme-linked immunosorbent assay-negative testing in individual milk samples of lactating cows. This case illustrates the strengths and limitations of the different laboratory tests and testing schemes for MAP screening in dairy herds. A cluster of MAP-shedding cattle on this farm was related to a birth cohort, which suggests a common source of infection early in life. Our observations stress the importance of preventive management to reduce the potential and hidden spread of MAP in test-negative herds.
