Comparison of ELISAs on milk and serum for the detection of paratuberculosis in dairy goats

摘要

Early detection of Mycobacterium paratuberculosis-infected animals is important for infection control and reduction of economic losses. Serologic tests using ELISA technology are popular because they are fast, inexpensive, and easily automated. Use of milk instead of serum for antibody detection could potentially make paratuberculosis surveillance even easier, more affordable and thus more accessible for the dairy goat industry. The aim of this study was to determine whether ELISA results obtained on milk can predict those for serum using a commercial ELISA kit on samples from dairy goats.
