Preliminary studies on humoral immune response of sheep to wohlfahrtiosis.

The humoral immune response of sheep to wohlfahrtiosis was studied. An enzyme-linked immunosorbent assay was developed to compare four different types of antigens obtained from the third-stage larvae of Wohlfahrtia magnifica. The antigen prepared from salivary glands detected a humoral response in all 35 infested sheep and was more specific in the ELISA than cuticular, intestinal or whole larval antigens. The level of the humoral response in sheep to wohlfahrtiosis differed according to the location of the wounds.
