Abstract

Abomasal lymphatic cannulation was performed on steers naturally or experimentally infected with Ostertagia ostertagi and Cooperia sp.. Abomasal lymphatic lymphocyte subpopulations were evaluated using antibodies specific for bovine mononuclear cell surface antigens, followed by flow cytometric analysis. When compared with the non-infected or experimentally infected steers, naturally infected steers with Type 1 or Type 2 ostertagiosis had increased percentages of B-lymphocytes. The percentages of B-lymphocytes were related to the numbers of O. ostertagi and Cooperia sp.. These findings are compatible with reports of worm-specific antibody synthesis in bovine nematodiases.
