In their quest for blood, most haematophagous parasites secrete vasodilators in their saliva to counter the host haemostatic response of vasoconstriction. Surprisingly, salivary gland extracts from adult female Dermacentor reticulatus and Rhipicephalus appendiculatus ticks induced constriction in a rat femoral artery model; males induced vasoconstriction or vasodilation depending on the time of...

The objectives of this study were to determine the diversity, seasonal dynamics and abundance of ticks infesting cattle in Isfahan zone, Iran. The study was conducted in three traditional cattle farms. No acaricides had been applied to cattle at the selected farms. Adult ticks were collected twice per month from different parts of the cattle's body. Environmental data, including relative humidi...

The species composition and geographic distribution of ixodid ticks infesting domestic dogs owned by people in rural communities and villages in Maputo Province was established by collecting ticks from dogs at each of 27 localities spread throughout the province. Ticks were collected from a total of 132 dogs, and nine species belonging to four genera were identified. One dog was infested with s...

DESIGN AND INTERVENTION BDUs of following four treatment categories were exposed to field populations of ticks: untreated (control), deettreated, permethrin-impregnated (PI), and permethrin-sprayed (PS). Six sites of 1ha (2.5 acres) were selected for a relative abundance of ixodid ticks. Sites were selected to ensure maximum exposure to (1) the ticks of all three growth stages — larval, nymphal...

This is a first molecular report investigate the phylogenic analysis of Theileria spp. in sheep and it's infested ticks Mosul city-Iraq. A total 185 blood samples were collected from different areas city. sixty five Ixodid also parts infected animals. The overall prevalence was 52.4% (97 out 185), for ovis it 9.7%, lestoquardi 20% mixed infection 22.7% city, based on conventional-PCR multiplex-...

BACKGROUND Tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group (SFG) rickettsiae. Although Spotted Fever is prevalent in the Middle East, no reports for the presence of tick-borne pathogens are available or any studies on the epidemiology of this disease in the West Bank. We aimed to identify the circulating hard tick vectors and genetical...

Five or 6 rock dassies (Procavia capensis) were shot at monthly intervals for 13 consecutive months in the Mountain Zebra National Park and processed for arthropod parasite recovery. Ten species of ixodid ticks and 2 flea species were recovered. The seasonal prevalence of the rock dassie ticks, Haemaphysalis hyracophila and Rhipicephalus distinctus, and of the immature stages of Rhipicephalus a...
