The economic importance of tick infestation on camels are important as they are important meat and milk producer animals in the less vegetation area of Iran and their health and production are greatly affected by the high tick infestation. In this investigation, tick infestations on camels (Camelus dromedarius) were determined in Qeshm Island, Iran. A total number of 912 adult ticks (472 males...
to assess hard ticks population on sangsari sheep breed under the effect of weather’s parameters such as duration of sun shine, humidity, ambient temperature, altitude, 5% of a flock (almost 1000 sheep in mountains and fields of semnan and tehran provinces) were randomly separated and were observed monthly. during a year, a total of 1505 hard ticks (635 females and 870 males) containing dermace...
Hard ticks spend most of their life isolated from passing vertebrates but require a blood meal to proceed to the next life stage (larva, nymph or adult). These opportunist ectoparasites must be capable of anticipating signals that render suitable hosts apparent. Large ungulates that tolerate a high ectoparasite burden are the favoured hosts of adult hard ticks. Ruminants, comprising the majorit...
Background and Aims: Ticks are external parasites that can be vectors of several diseases agents. A survey was carried out to determine distribution and biological diversity of hard tick species in Maraveh Tapeh County, Golestan Province in spring 2016. Materials and methods: In 10 selected villages in study area, About 29 cattle, 99 sheep, 62 goats and 11 camels were inspected for tick infest...
Background and purpose: Coxiella burnetii infection (causative agent of Q fever) is a public health problem and a zoonotic disease with a global prevalence. The importance of zoonotic diseases and their impact on the health of people in a community is undeniable. The aim of this study was to investigate the prevalence of Coxiella burnetii in hard ticks isolated from livestock in different parts...
background and aims: crimean-congo hemorrhagic fever (cchf) is a zoonosis caused by a nairovirus of the family bunyaviridae. infection is transmitted to humans mostly by hyalomma ticks. this study was conducted to determine the rate of cchfv infection in ticks in qom province of iran. materials and methods: in this study, reverse transcription – polymerase chain reaction (rt-pcr) was used to de...
African swine fever (ASF) is caused by African swine fever virus (ASFV), a tick-borne DNA virus. Soft ticks of the genus Ornithodoros are the only biological vectors of ASFV recognized so far. Although other hard ticks have been tested for vector competence, two commonly found tick species in Europe, Ixodes ricinus and Dermacentor reticulatus, have not been assessed for their vector competence ...
In recent years there has been much progress in our understanding of the phylogeny and evolution of ticks, in particular the hard ticks (Ixodidae). Indeed, a consensus about the phylogeny of the hard ticks has emerged which is quite different to the working hypothesis of 10 years ago. So that the classification reflects our knowledge of ticks, several changes to the nomenclature of ticks are im...
