Inverse relationship between IgE and worm burdens in cattle infected with Ostertagia ostertagi.
Changes in serum total and Ostertagia-specific IgE levels, and pepsinogen concentrations were evaluated in 28 Holstein calves naturally or experimentally infected with Ostertagia ostertagi. In addition, IgE and pepsinogen concentrations were determined in abomasal lymph. Results showed that (1) lymph IgE responses were inversely correlated with worm burdens, and (2) serum IgE levels were unreliable for predicting worm burdens.
