Dg. Baker et Lj. Gershwin, INVERSE RELATIONSHIP BETWEEN IGE AND WORM BURDENS IN CATTLE INFECTED WITH OSTERTAGIA-OSTERTAGI, Veterinary parasitology, 47(1-2), 1993, pp. 87-97
Changes in serum total and Ostertagia-specific IgE levels, and pepsino
gen concentrations were evaluated in 28 Holstein calves naturally or e
xperimentally 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 wor
m burdens, and (2) serum IgE levels were unreliable for predicting wor
m burdens.
