Attempted immunisation of crossbred calves (Bos taurus × Bos indicus) by repeated natural attachment of ticksHyalomma anatolicum anatolicum Koch (1844)

Abstract: Crossbred calves (Bos taurus x Bos indicus) were repeatedly infested with the ixodid tick, Hyalomma anatolicum anatolicum. The parameters of engorgement, pre-oviposition period, oviposition period, engorged weight, egg batch weight, and per cent hatch of eggs all showed statistically significant differences between first to tenth infestation. Only the time to engorgement did not change. It is concluded that repeated infestations of this tick stimulate acquired resistance.

“…Earlier, the involvement of salivary proteins of H. anatolicum in hypersensitivity reaction as an indicator of resistance against homologous challenge in rabbits has been reported by Gill et al [30]. Subsequently, a significant adverse effect on ticks fed on animals repeatedly infested with H. anatolicum was reconfirmed by Momin et al [31] and Singh et al [32]. Active immunization of rabbits with extracts of larvae resulted in significant protection against challenge infestation has been reported by Ghosh and Khan [33].…”

“…Subsequently, several workers reported comparatively higher adaptive immunity in laboratory animals than in natural hosts (Ribeiro, 1989). Momin et al (1991) and Singh et al (1991) reported significantly adverse effect on ticks fed on animals repeatedly infested with H. anatolicum and reconfirmed the earlier observations of Gill et al (1986). Ghosh et al (1998) immunized rabbits with extracts of larvae and nymphs and a significant reduction in the engorgement percentage, engorgement weight and egg masses in ticks fed on immunized animals compared to ticks fed on a control group of animals was recorded.…”
