molecular and serological detection of theileria equi and babesia caballi infection in horses and ixodid ticks in iran.equine piroplasmosis is a hemoprotozoan tick-borne disease with worldwide distribution that is caused by theileria equi and babesia caballi. however, the geographical distribution of equine piroplasmosis in iran is unknown. the aim of the current study was to determine the causative agents and vector ticks of equine piroplasmosis in horses in the north khorasan province. in the year 2011, 100 horses were randomly selected from 14 villages. blood samples and ixodid ticks were collected and examin ...201424556274
Crimean-Congo hemorrhagic fever virus in various ixodid tick species from a highly endemic area.Ticks are major vectors of numerous diseases affecting animals and humans. Presence of various tick-borne pathogens such as Crimean-Congo hemorrhagic fever virus (CCHFV) in various tick species was documented. CCHF is a severe tick-borne illness caused by the CCHFV which is a member of the Nairovirus genus (family: Bunyaviridae). Presence of CCHFV was shown in the most prevalent ixodid tick species such as Hyalomma marginatum and Rhiphicephalus bursa in Turkey. In the present study, prevalence a ...201122119389
the genus hyalomma koch, 1844. i. reinstatement of hyalomma (euhyalomma) glabrum delpy, 1949 (acari, ixodidae) as a valid species with a redescription of the adults, the first description of its immature stages and notes on its biology.for nearly 50 years the ixodid tick hyalomma marginatum turanicum, reputedly introduced into south africa on imported persian sheep, has been considered identical to the asian hyalomma (euhyalomma) marginatum turanicum pomerantzev, 1946. comparisons of this tick with the asian h. (e.) m. turanicum and other subspecies of hyalomma (euhyalomma) marginatum, however, reveal that it is an old taxon, namely hyalomma rufipes glabrum delpy, 1949. it is hereby reinstated as hyalomma (euhyalomma) glabrum, ...200616715874
parasites of domestic and wild animals in south africa. xviii. the crowned guinea fowl (numida meleagris), an important host of immature ixodid ticks.the tick burdens of 10 crowned guinea fowl (numida meleagris), shot at approximately 3-monthly intervals in the mountain zebra national park, and of 21 crowned guinea fowl from the andries vosloo kudu reserve, the majority of which were shot at monthly intervals, were determined. no adult ticks were recovered from any of the guinea fowl. the birds in the mountain zebra national park harboured 4 species of ixodid ticks of which amblyomma marmoreum was the most abundant and most prevalent. three b ...19863725331
comments on controversial tick (acari: ixodida) species names and species described or resurrected from 2003 to 2008.there are numerous discrepancies in recent published lists of the ticks of the world. here we review the controversial names, presenting evidence for or against their validity and excluding some altogether. we also address spelling errors and present a list of 17 species described or resurrected during the years 2003-2008. we consider the following 35 tick species names to be invalid: argas fischeri audouin, 1826, ornithodoros boliviensis kohls and clifford, 1964, ornithodoros steini (schulze, 1 ...200919169832
molecular detection of theileria spp. and babesia spp. in sheep and ixodid ticks from the northeast of iran.theilerioses and babesioses are important diseases in iranian sheep. the present study was undertaken to identify and classify/specify theileria spp. and babesia spp. in sheep and vector ticks. investigation was carried out from 2009 to 2011 in the khorasan razavi province, iran. in total, 302 sheep originating from 60 different flocks were clinically examined and their blood collected. in addition, from the same flocks, ixodid ticks were sampled. stained blood smears were microscopically examin ...201322924924
molecular detection of rickettsia africae, rickettsia aeschlimannii, and rickettsia sibirica mongolitimonae in camels and hyalomma spp. ticks from this study, we aimed to identify and genetically characterize spotted fever group (sfg) rickettsiae in ticks, domestic one-humped camels, and horses from farms and bedouin communities in southern israel. a total of 618 ixodid ticks (hyalomma dromedarii, hyalomma turanicum, hyalomma excavatum, and hyalomma impeltatum) collected from camels and horses, as well as 152 blood samples from 148 camels and four horses were included in the study. initial screening for rickettsiae was carried out by ta ...201324107206
the scrub hare, a reliable indicator of the presence of hyalomma ticks in the cape province.the host preferences of immature and adult hyalomma marginatum rufipes, hyalomma marginatum turanicum and hyalomma truncatum were studied at various localities in the cape province. the immature stages of all 3 ticks preferred scrub hares (lepus saxatilis) as hosts and were recovered from these animals even when few adult ticks were present on large herbivores in the locality. ground-frequenting birds were also infested, but only with immature h. marginatum rufipes and h. marginatum turanicum. s ...19873612673
molecular surveillance of theileria ovis, theileria lestoquardi and theileria annulata infection in sheep and ixodid ticks in iran.a molecular study was undertaken to detect theileria ovis, theileria lestoquardi and theileria annulata in sheep and tick vectors. investigation was conducted from 2010 to 2011 in the south of khorasan razavi province, iran. a total of 150 blood samples were collected from 30 different sheep flocks. in addition, ixodid ticks were sampled from the same flocks. the stained blood smears were microscopically examined for the presence of piroplasms and a semi-nested polymerase chain reaction-restrict ...201324396911
molecular detection of theileria spp. in sheep and vector ticks in the north khorasan province, iran.a survey was carried in north khorasan province, iran in 2010-2011, designed to identify theileria spp. infections of both sheep and ticks. the tick species were also examined. ninety sheep from different flocks were clinically examined, and blood samples and ixodid ticks were collected. light microscopy of blood smears revealed theileria spp. infection in 37 (41.1 %), while 74 (82.2 %) of blood samples were positive using semi-nested pcr. theileria ovis, theileria lestoquardi, and mixed infecti ...201322791188
