Ticks had to adapt to an existing and complex vertebrate hemostatic system from being free-living scavengers. A large array of anti-hemostatic mechanisms evolved during this process and includes blood coagulation as well as platelet aggregation inhibitors. Several questions regarding tick evolution exist. What was the nature of the ancestral tick? When did ticks evolve blood-feeding capabilitie...

At least 15 different infectious agents and diseases are transmitted or produced by ticks parasitizing dogs and cats in North America. Those infectious agents and diseases are distributed among eight different tick species that commonly infest dogs and cats. All but one of these species are hard ticks with a three-host development cycle in which each motile stage (larva, nymph, and adult) feeds...

Introduction Ticks are non-permanent obligate parasites that have considerable medical-veterinary and zoonosis importance. In this regard a study designed to investigate the distribution and fauna of ticks in the Alashtar county in Iran from April and March 2014. Methods Ticks were collected from livestock farms and facilities from selected rural and geographically location in the Alashtar co...

Hard ticks (Acari: Ixodidae) are known to harbour intracellular bacteria from several phylogenetic groups that can develop both mutualistic and pathogenic relationships to the host. This is of particular importance for public health as tick derived bacteria can potentially be transmitted to mammals, including humans, where e.g. Rickettsia or Coxiella act as severe pathogens. Exact molecular tax...

BACKGROUND As obligate blood-feeding arthropods, ticks transmit pathogens to humans and domestic animals more often than other arthropod vectors. Livestock farming plays a vital role in the rural economy of Pakistan, and tick infestation causes serious problems with it. However, research on tick species diversity and tick-borne pathogens has rarely been conducted in Pakistan. In this study, a s...

Tick-borne rickettsioses are emerging and re-emerging diseases of public health concern caused by over 30 species Rickettsia . Ticks obligate hematophagous arthropods with 700 Ixodid ticks known worldwide. The escalating geographical dispersal tick vectors concomitant increase in the incidences tick-borne have fueled interest ecology pathogens. This review focuses on aspects pathogen, including...

Background: Crimean-Congo hemorrhagic fever (CCHF) is a potentially fatal tick-borne viral disease. Hard ticks are both carriers and reservoirs of the CCHF virus. In this regard, the present study is aimed to investigate the CCHF virus infection in collected ticks from livestock in Gonabad City (southwest of Razavi Khorasan province) in eastern Iran. Methods: This descriptive study was perfo...

Hard ticks (Acari: Ixodidae) and tick-borne diseases are considered as a threat in several parts of Europe. In Finland, both Ixodes ricinus persulcatus have shifted northwards recent decades, they become more abundant at the same time. This is thought to be due global climate change its effect directly on or indirectly their host animals. review focuses factors that affect tick activity surviva...

Ticks are distributed worldwide and have an enormous medical and veterinary importance owing to the direct damage they cause to their hosts, and especially because these are vectors of a large variety of human and animal pathogens. In fact, ticks are second to mosquitoes as vectors of human pathogens and the most important vectors of pathogens affecting cattle worldwide [1-3]. Tick species can ...
