Studies on the pathogenicity of Cooperia curticei for sheep

Abstract

Extract

Cooperia curticei is commonly found in sheep in New Zealand, frequently in relatively large numbers. The pathogenicity of this nematode, for sheep has been the subject of few experimental studies; the evidence available suggests that C. curticei produces few pathological changes in sheep (Andrews, 1938), although it has been claimed to be highly pathogenic for goats (Edgar, 1936). In view of the little information available, some further investigation seemed justified. This paper describes briefly two experiments on the effect of C. curticei on sheep.
