Abstract:The immunological studies of salivary gland antigen of
Rhipicephalus haemaphysaloides in rabbits was carried out in the department of Parasitology, Nagpur Veterinary College, Nagpur. Maharashtra Animal and Fishery Sciences University, Nagpur. Partially fed
R. haemaphysaloides ticks were used for collection of salivary gland. The concentration of protein was estimated to be 2.1 mg/ml of antigen. Crude salivary gland antigen of
R. haemaphysaloides was characterized by SDS-PAGE, which revealed 17 protein bands. It is followed by alkaline, acidic and sodium phosphate buffer treatment. Raising of hyperimmune sera was done in New Zealand white rabbits in divided doses on day 0, 14 and 28 followed by blood collection. Second booster dose was given at 2 weeks interval and final blood collection was performed 2 weeks post second booster.
The test was conducted for group I and II (control group) by using sera collected from animals on 0, 14, 28 and 42 days following immunization. Prominent precipitation line appeared only from 10 days – II booster which persisted 42 days post II booster in animals belonging to group I. No such reaction was observed in group II control rabbits.
