[The T-cell response in parasitization by sheep bot (Oestrus ovis) larvae].
The kinetics of immunocompetent cells in sheep artificially infested with 80, 160, 1000 specimens of Oestrus ovis larvae and immunized with antigen from larvae protein was traced by stableons (E-REC) and antigen-fixing (Ag-REC) rosette formation reaction. It was found that E-REC level changes only a little in both infested and reinfested animals. Ag-REC kinetics mates with the rated larvae biomass changes in all age groups. Ag-REC level of infested animals is much higher and then regularly declines in the following cycles of invasion. T-lymphocytes level and death level of immunized lambs is much higher than in intact animals at the beginning of parasitism.
