Summary

Species of Marshallagia are abomasal parasites in free-ranging and domesticated ungulates in temperate climatic zones throughout the world. Pervasiveness of these nematodes is significant in various parts of the world. There has been limited research in the area of Marshallagi amarshalli pathogenesis. The aim of this study was to investigate the effects of M. marshalli on the acid secretory capacity of the abomasal mucosa and the morphological changes due to parasitic migration to different parts of abomasal tissue in sheep. Ten lambs, approximately around 6 months old, were allotted to two groups of five (A and B). The sheep from group A were infected orally with a dose of 5000 third-stage larvae (L3) of M. marshalli whereas the sheep of group B were not infected. The results indicated that the development of M. marshalli in the abomasal glands of ruminants causes pathophysiological changes, which include a reduced acidity of the abomasal contents, increased abomasal pH and increased serum pepsinogen concentrations. The reduced acid secretion is explained by a replacement of functional parietal cells by undifferentiated cells. Histology changes include mucosal cell hyperplasia, loss of parietal cells and inflammatory cell infiltration, which includes numerous granulocytes and lymphocytes.
