Recognition of low molecular weight Cooperia oncophora antigens after primary and trickle infection of calves with third-stage infective larvae.


Recognition of low molecular protein fragments of adult Cooperia oncophora of calves was studied using sera obtained after a single oral (primary) infection with 100,000 infective 3rd-stage C. oncophora larvae, and after a 10-week period of trickle infection with moderate doses of these larvae. SDS-gel electrophoresis under reducing conditions, followed by… (More)
