Ostertagia ostertagi, calves (nat. and exper.), type I ostertagiasis, assay of lymphocyte reactivity to O. ostertagi L3 antigen and phytohemagglutinin, possible lack of genus specificity to antigen shown by reaction using lymphocytes from Cooperia punctata-infected calves, kinetics of lymphocyte reactivity showed transient nonspecific suppression of cell-mediated immune responses during prepatent periods of type I ostertagiasis, immunosuppression phenomenon may have role in O. ostertagi pathogenesis and development of immunity
