Oestrus ovis Linnaeus 1761 (Diptera : Oestridae) is the almost cosmopolitan and well known myiasis causing dipterous insect species which affects the health of sheep and goats in many parts of the world.

The study aimed to investigate the effect of Echinacea Purpurea (E) root extract oral supplementation on immune response of New Zealand White rabbits using sheep red blood cells (SRBC) as antigen. The study used three groups of rabbits each of ten animals. The first group is normal control administered water orally and injected intramuscular with 1ml of (NaCl 0.9%). The second immunized non-treated group (INT): administered water orally and injected intramuscular with 1ml of Sheep Red Blood Cells (SRBC) suspension. The third Immunized E treated group (IT): treated with (E) purpurea 130 mg/kg for ten days orally subsequent to intramuscular injection with 1ml of (SRBC) suspension. The effect of Echinacea after ten days of supplementation on immune response estimated by measuring total leucocyte and total lymphocyte count. Serum tested for antibody titer by passive hemagglutination test and the titer estimated in groups for 3, 7 and 10 days post immunization and Echinacea treatment. Treatment with Echinacea in IT group showed significant increase in total leukocyte count and lymphocyte% and the antibody titer compared to results in (INT) group. The results suggest the immune response enhancement efficacy of Echinacea purpurea root extract supplementation to SRBCs immunized rabbits.
