background: ticks are the main vectors for transmission of different pathogens to human and animals. this survey was performed to find out distribution of ticks, which infested the domestic ruminants in yazd province, central iran during year 2008-2009. methods: a total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. ticks were...

introduction crimean-congo hemorrhagic fever (cchf) is an acute viral zoonotic disease, which is endemic in vast geographic areas including the middle east. the causative agent, crimean-congo hemorrhagic fever virus (cchfv), is a nairovirus, which is mainly transmitted to human from infected hard ticks and viremic livestock. discussion given that viremic livestock are the main source of cchf ou...

background: hyalomma anatolicum is the well-known hard tick, which is one of the most important livestock and hu­man pathogens vector, wide range in host and distributed in all over the hyalomma geographic fauna as well as in iran. taxonomy of the hyalomma ssp. is debatable whereas their identification is a problematic work. the reasons for this claim is time consuming delpy’s researches in ira...

Abstract Spirochetes of the family Borreliaceae are, with one exception, tick-borne pathogens a variety vertebrates. The at present comprises two genera: Borrelia (Swellengrebel), which includes agents relapsing fever, avian spirochetosis, and bovine borreliosis, Borreliella (Gupta et al.), Lyme disease was formerly known as ‘Borrelia burgdorferi sensulato complex’. genera are distinguished not...

Two highly abundant lipocalins, monomine and monotonin, have been isolated from the salivary gland of the soft tick Argas monolakensis and shown to bind histamine and 5-hydroxytryptamine (5-HT), respectively. The crystal structures of monomine and a paralog of monotonin were determined in the presence of ligands to compare the determinants of ligand binding. Both the structures and binding meas...

The evidence that climate warming is changing the distribution of Ixodes ticks and the pathogens they transmit is reviewed and evaluated. The primary approaches are either phenomenological, which typically assume that climate alone limits current and future distributions, or mechanistic, asking which tick-demographic parameters are affected by specific abiotic conditions. Both approaches have p...
