Resistance to Rhipicephalus evertsi evertsi in immunosuppressed rabbits.
Rabbits treated with goat anti-rabbit thymocyte serum acquired less resistance to Rhipicephalus evertsi evertsi infestation than untreated controls. This inferior resistance was manifested as higher engorged weights of ticks and higher biotic potential, undue persistence of the ticks on the hosts and poor anti-tick antibody and delayed-type hypersensitivity responses. These observations highlight the significance of host T-cells in mediating resistance to ticks.
