| serological evaluation of crimean-congo hemorrhagic fever in humans with high-risk professions living in enzootic regions of isfahan province of iran and genetic analysis of circulating strains. | crimean-congo hemorrhagic fever (cchf) is a zoonotic viral disease that is asymptomatic in infected livestock, but causes a serious threat to humans with a mortality rate up to 50%. although the cchf virus (cchfv) is often transmitted by ticks, livestock-to-human and human-to-human transmission also occurs. in the current study, we focused on cchf in the province of isfahan, located in the center of iran and deemed to be the second most infected province. human and livestock sera and resident ti ... | 2012 | 22217167 |
| evaluation of different nested pcrs for detection of anaplasma phagocytophilum in ruminants and ticks. | anaplasma phagocytophilum is a causative agent of granulocytic anaplasmosis in mammals, which has a broad geographical distribution and a high degree of clinical diversity. currently, numerous pcr assays have been developed and used for the detection of a. phagocytophilum in various specimens. however, their performance varies. the aim of this study was to evaluate the performance of five nested pcr assays by detection of 363 ruminant and tick samples, and to select the most appropriate methods ... | 2016 | 26911835 |
| crimean-congo hemorrhagic fever in iran. | the presence of crimean-congo hemorrhagic fever virus (cchfv) in iran was first identified in studies of livestock sera and ticks in the 1970s, but the first human infection was not diagnosed until 1999. since that time, the number of cases of cchf in iran has markedly increased. through january 2012, articles in the published literature have reported a total of 870 confirmed cases, with 126 deaths, for a case fatality rate (cfr) of 17.6%. the disease has been seen in 26 of the country's 31 prov ... | 2013 | 23872313 |
| molecular detection and identification of spotted fever group rickettsiae in ticks collected from the west bank, palestinian territories. | tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group (sfg) rickettsiae. although spotted fever is prevalent in the middle east, no reports for the presence of tick-borne pathogens are available or any studies on the epidemiology of this disease in the west bank. we aimed to identify the circulating hard tick vectors and genetically characterize sfg rickettsia species in ixodid ticks from the west bank-palestinian territories. | 2016 | 26771654 |
| a survey of ixodid tick species and molecular identification of tick-borne pathogens. | this study was undertaken in two different climatic areas of turkey to determine the presence of tick-borne pathogens of medical and veterinary importance. the ticks were removed from humans, pooled according to species and developmental stages, and analyzed by pcr, reverse line blot (rlb) and sequencing. of the 2333 removed ticks from 10 species, 1238 (53.06%) were obtained from the arid cold zone, and the remaining 1095 (46.93%) were obtained from the humid zone. the removed ticks were identif ... | 2014 | 24424312 |
| lyme borreliosis spirochetes and spotted fever group rickettsiae in ixodid ticks from pianosa island, tuscany archipelago, italy. | a study on tick fauna and tick-borne pathogens was undertaken in pianosa, an island in the tuscany archipelago that constitutes an important stopping and nesting point for migratory birds. ticks were removed from feral cats and a few terrestrial birds, and host-seeking ticks were collected by dragging. a total of 89 ticks were found on animals: 57 ixodes ventalloi gil collado, 1936 and 32 ixodes acuminatus neumann, 1901. host-seeking ticks were 354 hyalomma spp. larvae and 18 hyalomma spp. adult ... | 2013 | 23289398 |
