The Molecular Diversity of Strains of Ostertagia ostertagi

[摘要] Increasing evidence for the occurrence of intraspecific variation of nematodes prompted this study of Ostertagia ostertagi, a parasite of the bovine abomasum which causes gastroenteritis. Parasites recovered from calves with ostertagiosis have shown differences in their morphology, pattern of development and drug susceptibility. These factors led to experimental work to assess the degree of variation detectable at a molecular and structural level. The techniques applied examined the genetic products of different isolates of O. ostertasi and also compared them to other trichostrongyle species. In addition, the stages of the parasite life cycle were followed.
