Problem statement: The consumption of black cumin (Nigella sativa) seed has immunomodulatory and anti-bacterial activity, but in rabbits this had not yet been tested. Approach: In the present studies, rabbits were fed diets without or with black cumin seed and antibody production, phagocytotic activity, hypersensitivity and resistance against Pasteurellosis were assessed. Results: Feeding black cumin seed significantly increased serum concentrations of antibodies in response to intramusculary injected serum bovine albumin. Blood derived from rabbits fed the diets containing either 15 or 20% black cumin seed significantly reduced the growth of Staphylococcus aureus on sheep-blood agar plates. Skin thickness as index of hypersensitivity towards tuberculin was significantly reduced at 48 h after intradermal injection of the agent. Ingestion of black cumin seed significantly extended survival time after intraperitoneal administration of Pasteurella multocida. Conclusion: The feeding of black cumin seed to rabbits stimulated their immune system, but did not enhance inflammation.
