Heterotopic Parasitism of Setaria digitata in the Heart of Eight Cattle

Abstract

Nematodes were collected from the epicardium of the ventricles and from the pericardium in 8 cattle slaughtered at an abattoir for three winter months. They were all identified morphologically as the immature worms (2 males and 8 females) of Setaria digitata (von Linstow, 1906). It was suggested that the bovine heart might be one of the sites of heterotopic parasitism of S. digitata.
