Conteúdo: | Abstract : Subcutaneous injections of Oesophagostomum columbianum larvae failed to protect lambs against challenge infections, although symptoms in some lambs were less severe. Subcutaneous infections appeared to sensitize most lambs and oral challenge infections were retained as histotropic larvae in the small intestine over longer periods. Much more severe inflammatory reactions resulted. Prior subcutaneous infection had little effect on host- parasite relationships as seen in the large intestine. A corticosteroid greatly reduced host inflammatory response to histotropic larvae, but host-parasite interactions varied considerably within the group of lambs so treated. No significant variation of host-parasite interaction was observed in lambs given 6-mercaptopurine or antihistamine. [A.S.] J.N.O.
