Immunization of Cattle Against Ticks
Mohamed Saad Moustafa Gabr El-Nabarawy;
Abstract
One of the greatest problems hindering the successful increase of animal production and the most destructive enemies of our animal wealth in Egypt is infestation by ticks.
Ticks are responsible for severe economic losses both through the direct effect of blood sucking and indirectly as vectors of some pathogens and its paralytic toxins. Ticks not only act as vectors of diseases but also serve as reservoirs of certain infedious agent.
Ticks devour large quantities of blood and their wounds are subject to secondary bacterial infection. Severe infestation can cause anemia, weight loss; decline in milk yield and death of the host. Ticks bites also reduce the quality of Irides. The major losses however, caused by ticks are due to their ability to _transmit pathogens which are of great economic importance worldwide.
El-Kady (1998) reported that the protozoal organisms present in ticks were Babesia sp., Theileria sp., Anaplasma sp. and Trypanosoma sp. The ticks also transmit vnuses e.g. Arboviruses, reckittsial, spirochetes and bacteria e.g. . Francisella tularensis which cause tularemia disease.
The principal tick control method is application of acaricides. This approach is however associated with a number of disadvantages such as, environmental and residual problems, the cost of the chemicals and
