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
Species distribution and detection of Crimean Congo Hemorrhagic Fever Virus (CCHFV) in field-collected ticks in Ankara Province, Central Anatolia, Turkey.Ticks may act as vectors for a number of infectious diseases including Crimean Congo Hemorrhagic Fever (CCHF). The causative agent is Crimean Congo Hemorrhagic Fever Virus (CCHFV), a member of Bunyaviridae, causing extensive ecchymosis, visceral bleeding and hepatic dysfunction with a high fatality rate in the affected individuals. CCHF was initially recognized in Turkey in 2002 and the current number of reported cases exceeds 4,400. This study was conducted to confirm the presence of tick speci ...201221910017
crimean-congo hemorrhagic fever in european part of turkey: genetic analysis of the virus strains from ticks and a seroepidemiological study in humans.abstract a survey of ticks from domestic ruminants, together with a serosurvey in humans was conducted in thrace (northwestern turkey) to evaluate the prevalence of crimean-congo hemorrhagic fever virus (cchfv) in ticks and humans. more prevalent ticks were hyalomma marginatum, hyalomma aegyptium, rhipicephalus bursa, and rhipicephalus (boophilus) annulatus, with low numbers of dermacentor marginatus, rhipicephalus sanguineus group, and ixodes ricinus. no differences in the tick faunal compositi ...201021028961
detection of babesia ovis by pcr in rhipicephalus bursa collected from naturally infested sheep and goats.polymerase chain reaction (pcr) was used to assess the presence and the frequency of babesia ovis infection in the adult rhipicephalus bursa and their hosts in elazig province located in eastern turkey. tick and blood samples were collected from 32 sheep and 28 goats of four selected herds. a total of 226 r. bursa were randomly selected from the collected ticks and their salivary glands were dissected out in 0.85% saline under stereo microscope. dna amplification method revealed that the frequen ...200817881019
[determination of tick species and treatment of cows, sheep and goats in the sivas-zara region].the purpose of this study was to examine tick infestation in cattle, sheep and goats in the zara-sivas region for one year and to determine the epizootiology of the tick species as well as to investigate treatment of the infested animals. tick infestation was detected in 71 (29.6%) out of 240 cattle, 66 (24.0%) out of 275 sheep and 50 (19.9%) out of 252 goats in the zara region. it has been shown that the tick infestation on cattle included haemaphysalis parva (33.8%), dermacentor marginatus (2. ...200617160854
genetic analysis of the m rna segment of crimean-congo hemorrhagic fever virus strains in turkey.crimean-congo hemorrhagic fever (cchf) virus is member of the genus nairovirus of the family bunyaviridae. all members of the family bunyaviridae are enveloped viruses containing tripartite, negative polarity, single-stranded rna. cchf is characterized by high case mortality, occurring in asia, africa, the middle east and europe. during recent years, outbreaks have been reported in turkey. however, little information is available on the genetic diversity of cchf virus in turkey. in this study, a ...200817955162
molecular detection and identification of ehrlichia and anaplasma species in ixodid ticks.a polymerase chain reaction (pcr) assay followed by partial sequencing of the 16s ribosomal rna gene was performed for the presence of ehrlichia and/or anaplasma. a total of 242 ixodid ticks were collected from domestic ruminants and their shelters, as well as humans, and their individual salivary glands were dissected out for dna. from the 242 ticks analyzed, six (2.47%), comprising three hyalomma anatolicum anatolicum, one rhipicephalus bursa, and two rhipicephalus sanguineus, were positive. o ...200919247690
ixodid ticks (acari: ixodidae) infesting humans in tokat province of turkey: species diversity and seasonal activity.ixodid ticks (acari: ixodidae) are the major vectors of pathogens threatening animal and human health. tokat province, turkey, is a suitable habitat for extended tick activity with its moderate climate and vegetation. in the present study, we surveyed humans visiting health centers to determine the species diversity, geographical distribution, and seasonal activity of ixodid ticks infesting them. out of 5,999 adult ticks collected from humans from april to september, 2008, 800 ticks were identif ...201020618665
a molecular survey of bovine theileria parasites among apparently healthy cattle and with a note on the distribution of ticks in eastern turkey.a survey of theileria parasites in cattle in eastern turkey was carried out using specific polymerase chain reaction. a total of 252 blood samples were collected from clinically healthy cattle between june and july 2004. of 252 blood samples examined, 41 (16%) were positive for piroplasms by microscopy, whereas 114 (45%) were positive for the presence of at least one species of theileria by pcr. the percentages of positive animals for theileria annulata and benign theileria species (theileria se ...200616510248
pcr-based detection of theileria ovis in rhipicephalus bursa adult ticks.tick-borne diseases in ruminants are common in tropical and subtropical regions and lead to meat and milk production losses. in this study, polymerase chain reaction (pcr) was used to assess the presence of theileria ovis in rhipicephalus bursa ticks. we have demonstrated that the pcr enabled detection of t. ovis in field isolates of r. bursa collected from naturally infested sheep and goats in eastern turkey. the sampling was done in spring season (between may and june 2004). a total of 420 r. ...200616682122
species diversity of ixodid ticks feeding on humans in amasya, turkey: seasonal abundance and presence of crimean-congo hemorrhagic fever virus.ticks (acari:ixodidae) are important pests transmitting tick-borne diseases such as crimean-congo hemorrhagic fever (cchf) to humans. between 2002 and 2009, numerous cchf cases were reported in turkey, including amasya province. in the current study, species diversity, seasonal abundance of ticks, and presence of cchf virus (cchfv) in ticks infesting humans in several districts of amasya province were determined. in the survey, a total of 2,528 ixodid ticks were collected from humans with tick b ...201121337953
crimean-congo hemorrhagic fever virus in ticks collected from humans, livestock, and picnic sites in the hyperendemic region of turkey.abstract during june and july 2007, about 3125 adult ticks were collected from humans, animals, and vegetation in a hyperendemic region (sivas and tokat) of turkey. a total of 2193 ticks were pooled in 225 pools and screened for the crimean congo hemorrhagic fever virus (cchfv) presence by antigen-capture enzyme-linked immunosorbent assay. infection rates were calculated as the maximum likelihood estimation with 95% confidence intervals (ci). the dominant tick species was found to be hyalomma ma ...201121736490
