Background: The cattle tick, Rhipicephalus (Boophilus) microplus, affects livestock production in many regions of the world. Up to now, the widespread use of chemical acaricides has led to the selection of acaricide-resistant ticks and to environmental contamination. Gavac is a subunit vaccine based on the recombinant Bm86 tick antigen expressed in yeast, capable to control infestations of R. m...

The current study was carried out on blood samples of 299 local breed female cattle in Erbil, Duhok and Suleimania, Northern Iraq, for the period from beginning of January till end of December 2006 for detection of piroplasmosis. By direct blood smear examination, the rate of Theileria annulata alone was 45.1% while in mixed infections with Babesia was 11.7%. The total rate of Theileria infecti...

The efficacy of amitraz on cattle ticks was assessed by susceptibility tests, spraying and dipping trials. Tests on the susceptibility of three tick species, Rhipicephalus appendiculatus, Amblyomma variegatum and Boophilus decoloratus to amitraz (technical grade-purity 98.6% w/w) showed all 15 tick strains tested to be highly susceptible, with LC50 ranging between 0.001% and 0.03%, and LC99, be...

Imported from Africa in the 1700s and despite frequent modern eradication efforts, Amblyomma variegatum (F.) spread through the Caribbean by cattle transport, small ruminants, and migrating birds. A. variegatum is a vector for Rickettsia africae, the causative agent of African tick bite fever, and Ehrlichia ruminantium, the causative agent of heartwater. We examined 95 A. variegatum and six Rhi...

The growing resistance of ticks to synthetic pyrethroids is a serious global problem that motivating researchers identify new biomolecules with broad acaricidal activity. Plants and their derivatives are often used in traditional medicine. This the purpose present study which focused on comparative effect an ointment based cashew balsam inothrin 5% Borgou cattle. During study, were collected th...

Ticks are harmful blood sucking external parasites of livestock that distributed in all agro-ecological zones Ethiopia. A cross sectional study was conducted to identify major tick genera, prevalence and assess infestation load on cattle Ambo district West shoa zone Oromia regional state.

Dairy cattle farming is of great economic and social importance in all Brazilian's regions. Parasites can reduce milk productivity, especially the tick Rhipicephalus (Boophilus) microplus. This study consisted of a questionnaire answered by 40 milk producers in the northwestern region of the State of São Paulo. The aim was to ascertain how these producers controlled ticks and other parasites. V...

A cross-sectional survey was undertaken on 240 dairy cattle farms in Nyandarua District in central Kenya to determine farm characteristics, farmer’s perception of production constraints and diseases and the prevalence and control practices for ticks and helminths. Farmers were interviewed using questionnaires and 708 cattle examined. The mean farm size was 3.2 hectares and average number of cat...

Tick-borne ehrlichial pathogens of animals and humans require a mammalian reservoir of infection from which ticks acquire the organism for subsequent transmission. In the present study, we examined the strain structure of Anaplasma marginale, a genogroup II ehrlichial pathogen, in both an acute outbreak and in persistently infected cattle that serve as a reservoir for tick transmission. Using t...

background: considering the importance of ticks as a main group transmitting pathogen organisms, this study de­signed to recognize immunogenic proteins in different tissues of rhipicephalus ( boophilus ) annulatus tick and to find out if there are common proteins in these tissues. methods: seven cattle were experimentally infested with about 10000 r. annulatus larvae and their humoral im­mune r...
