Ticks are distributed worldwide and significantly impact human and animal health. Due to severe problems associated with the continuous use of acaricides on animals, integrated tick management is recommended. Increasing public health concern over the tick-borne diseases demands the strategic control of ticks on animals that transmit diseases to human(More)
Extracts were prepared from leaf, bark, and seed of Azadirachta indica, leaf and seed of Prunus persica, bark of Mangifera indica, and leaf of Psidium guajava and were evaluated against Boophilus microplus. Of the eight extracts screened, the extracts prepared from the A. indica seed showed very high level of efficacy (80%) after 5 h of treatment. Besides(More)
The Bm86 homologue of Hyalomma anatolicum anatolicum Izatnagar isolate was cloned and expressed in methylotropic yeast Pichia pastoris as intracellular, glycosylated and particulated form. It was named as rHaa86, the first recombinant protein of H. a. anatolicum. Seven epidermal growth factor-like domains predicted in Haa86 were structurally similar with(More)
India is predominantly an agricultural country with about 70% of her population dependent on income from agriculture. Although India accounts for a significant share of world’s livestock resources, livestock production is greatly affected by ticks and tick-borne diseases (TTBDs). Therefore, India represents a particularly interesting scenario for the study(More)
Hyalomma anatolicum anatolicum is a three-host tick which transmits Theileria annulata infection in Indian cattle. Laboratory rearing of ixodid ticks is an essential requirement of any laboratory engaged with research on ticks and tick borne diseases. The Entomology laboratory of Indian Veterinary Research Institute is fully equipped with all the facilities(More)
BACKGROUND & OBJECTIVES On global basis, ticks transmit a number of pathogens than any other arthropod vector, and are among the most important vectors of diseases affecting humans, livestock and companion animals. Control of the vector has been focused on integrated management involving strategic use of insecticides, use of vaccines, use of herbal(More)
Hyalomma anatolicum anatolicum, a three host tick vector transmitting the causative agent of bovine tropical theileriosis, is widely distributed throughout India. As a component of integrated control measures against the tick vector, attempts have been made to identify candidate protein molecules for development of an anti-tick vaccine in the different(More)
The use of tick vaccine in controlling ticks and tick borne diseases has been proved effective in integrated tick management format. For the control of H. a. anatolicum, Bm86 ortholog of H. a. anatolicum was cloned and expressed as fusion protein in E. coli as E. coli-pETHaa86. The molecular weight of the rHaa86 was 97 kDa with a 19 kDa fusion tag of(More)
In an attempt to develop vaccine against Hyalomma anatolicum anatolicum, the protective efficacy of rHaa86 was evaluated against experimental challenge infestations of homologous tick species and lethal dose of Theileria annulata. Following challenge, a significant difference of 20.9% (P < 0.01) in the dropping per cent of ticks fed on immunized and control(More)
Hyalomma anatolicum anatolicum and Rhipicephalus (Boophilus) microplus are the most economically important tick species in India and other tropical and subtropical regions of the world and transmit pathogens causing animal and human diseases. We demonstrated that vaccination of animal by rHaa86 could be used for the control of both H. a. anatolicum and R.(More)
