Abstract
|
|
|
Haemaphysalis longiscornis is the common cattle tick of great economic importance in Korea. Chemical control using dips or sprays has been the traditional method of attempting to kill these ticks during the infestation period. However, the presence of resistant forms to chemical, the rising costs of acaricides and environmental problems have made it almost impossible to use these chemicals on a regular basis according to the pest problem.
For this reason, vaccination against ticks and breeding for host resistance against ticks are being studied.
In order to determine the common proteins and antigens according to developmental stages, SDS-PAGE and western blotting were performed. In SDS-PAGE 103.3kD and 98.3kD proteins were observed as common proteins, and these proteins were observed as common antigens in western blotting.
Unimmunized rabbits were infestated three times with H longicornis. The weight of the second and the third engorged ticks were 0.153g and 0.104g respectively. This weight is 69% and 47% of the first engorged ticks weight respectively.
Immunized rabbits by adult ticks antigen and control were infested with H longicornis. The control taked 3-4 days to fully engorge, but the immunized rabbits taked about 7 days. So adult tick antigen may be effective to render the immunity to host.
