| molecular detection of crimean-congo haemorrhagic fever virus in ticks collected from infested livestock populations in a new endemic area, south of iran. | crimean-congo haemorrhagic fever (cchf) is a viral zoonotic disease with potentially fatal systemic effects on man. we aimed to determine the presence of cchf virus among collected ticks from domestic livestock from october 2012 to september 2013. | 2016 | 26758985 |
| crimean-congo hemorrhagic fever virus lineages europe 1 and europe 2 in bulgarian ticks. | crimean-congo hemorrhagic fever (cchf) is a tick-borne human viral disease with fatality rate up to 30%. two genetic lineages of cchf virus (cchfv) are present in europe - lineage europe 1 which contains pathogenic cchfv strains, and lineage europe 2 consisting of ap92 and ap92-like strains. in order to investigate cchfv distribution and potential risk for humans, ticks were collected from livestock in the five districts where cchf cases have been reported in the last five years in bulgaria. cch ... | 2016 | 27378409 |
| molecular assay on crimean congo hemorrhagic fever virus in ticks (ixodidae) collected from kermanshah province, western iran. | crimean-congo hemorrhagic fever (cchf) is a feverous and hemorrhagic disease endemic in some parts of iran and caused by an arbovirus related to bunyaviridae family and nairovirusgenus. the main virus reservoir in the nature is ticks, however small vertebrates and a wide range of domestic and wild animals are regarded as reservoir hosts. this study was conducted to determine the infection rate of cchf virus in hard ticks of sarpole-zahab county, kermanshah province, west of iran. | 2016 | 27308296 |
