Effect of successive infestation of adult ticks of hyalomma annatolicum on chinchilla rabbits

ABSTRACT

The effect of successive infestation of Hyalomma annatolicum annatolicum adult ticks was studied on Chinchilla Rabbits. The difference in engorgement blood ingestion in the first application in the experimental animals was insignificant but on second application on the experimental animals it was significant as compared to the control animals. In the third and fourth applications the experimental animals the difference in the engorgement was more reduced as compared to the control animals [P <0.05]. Therefore it is concluded that engorgement was reduced due to the development of immunity of the skin by subsequent infestation of adult ticks on Chinchilla Rabbits
