Dynamics of antibodies against hypodermin C in reindeer infested with the reindeer warble fly, Hypoderma tarandi.

Serum samples from 25 reindeer (Rangifer tarandus tarandus) were assayed for antibody against hypodermin C (HyC) using an ELISA. Nineteen animals were calves (born in 1998, 1999 or 2001) and six were adults (3-10 years old at first blood collection). The samples were collected over periods of 4 months (calves born in 2001) or 27 months (adults and calves born in 1998 and 1999), the latter encompassing three Hypoderma tarandi infestation seasons.
