Experimental concurrent infections with Ostertagia ostertagi and Cooperia oncophora in the calf
Satrija, F. | Nansen, P.
An experiment was conducted to investigate the effects of experimental concurrent infection with Ostertagia ostertagi and Cooperia oncophora compared with the effects of monospecific infections with O ostertagi under conditions designed to mimic natural conditions on pasture during a grazing season. The present experiment was not able to demonstrate any significant effect of C oncophora on the course of an O ostertagi infection. Neither did C oncophora influence the build up of immunity to O ostertagi as demonstrated by post mortem worm count results from challenge infections with hypobiosis-prone larvae.
