| a global genomic characterization of nairoviruses identifies nine discrete genogroups with distinctive structural characteristics and host-vector associations. | nairoviruses are primarily tick-borne bunyaviruses, some of which are known to cause mild-to-severe febrile illness in humans or livestock. we describe the genome sequences of 11 poorly characterized nairoviruses that have ecological associations with either birds (farallon, punta salinas, sapphire ii, zirqa, avalon, clo mor, taggert, and abu hammad viruses), rodents (qalyub and bandia viruses), or camels (dera ghazi khan virus). global phylogenetic analyses of proteins encoded in the l, m, and ... | 2016 | 26903607 |
| unprecedented genomic diversity of rna viruses in arthropods reveals the ancestry of negative-sense rna viruses. | although arthropods are important viral vectors, the biodiversity of arthropod viruses, as well as the role that arthropods have played in viral origins and evolution, is unclear. through rna sequencing of 70 arthropod species we discovered 112 novel viruses that appear to be ancestral to much of the documented genetic diversity of negative-sense rna viruses, a number of which are also present as endogenous genomic copies. with this greatly enriched diversity we revealed that arthropods contain ... | 2015 | 25633976 |
| ecology of the tick-borne phlebovirus causing severe fever with thrombocytopenia syndrome in an endemic area of china. | severe fever with thrombocytopenia syndrome (sfts) is caused by sfts virus (sftsv), a tick-borne phlebovirus in family bunyaviridae. studies have found that humans, domestic and wildlife animals can be infected by sftsv. however, the viral ecology, circulation, and transmission remain largely unknown. | 2016 | 27035712 |
| experimental and natural infections of goats with severe fever with thrombocytopenia syndrome virus: evidence for ticks as viral vector. | severe fever with thrombocytopenia syndrome virus (sftsv), the causative agent for the fatal life-threatening infectious disease, severe fever with thrombocytopenia syndrome (sfts), was first identified in the central and eastern regions of china. although the viral rna was detected in free-living and parasitic ticks, the vector for sftsv remains unsettled. | 2015 | 26485390 |
| characterization of haemaphysalis flava (acari: ixodidae) from qingling subspecies of giant panda (ailuropoda melanoleuca qinlingensis) in qinling mountains (central china) by morphology and molecular markers. | tick is one of important ectoparasites capable of causing direct damage to their hosts and also acts as vectors of relevant infectious agents. in the present study, the taxa of 10 ticks, collected from qinling giant pandas (ailuropoda melanoleuca qinlingensis) in qinling mountains of china in april 2010, were determined using morphology and molecular markers (nucleotide its2 rdna and mitochondrial 16s). microscopic observation demonstrated that the morphological features of these ticks were simi ... | 2013 | 23894541 |
| identification, distribution and population dynamics of francisella-like endosymbiont in haemaphysalis doenitzi (acari: ixodidae). | francisella-like endosymbionts (fles) with significant homology to francisella tularensis (γ-proteobacteria) have been characterized in several tick species, whereas knowledge on their distribution and population dynamics in ticks remains meager. hence, in the current study, we identified a novel francisella-like endosymbiont (fles-hd) from the tick haemaphysalis doenitzi and evaluated the putative functions of this symbiont. results indicated that fles-hd had 100% infection rate and a perfect v ... | 2016 | 27731377 |
| identification of a new type of babesia species in wild rats (bandicota indica) in chiang mai province, thailand. | a new type of rodent babesia, which resembled babesia microti but was phylogenetically placed closest, with the highest level of statistical support, to babesia canis, a canine babesia, was identified in thai bandicota indica in thai provinces to which malaria is endemic. close watch should be kept on human babesiosis in thailand. | 2004 | 14766871 |
| identification of 24h ixodes scapularis immunogenic tick saliva proteins. | ixodes scapularis is arguably the most medically important tick species in the united states. this tick transmits 5 of the 14 human tick-borne disease (tbd) agents in the usa: borrelia burgdorferi, anaplasma phagocytophilum, b. miyamotoi, babesia microti, and powassan virus disease. except for the powassan virus disease, i. scapularis-vectored tbd agents require more than 24h post attachment to be transmitted. this study describes identification of 24h immunogenic i. scapularis tick saliva prote ... | 2015 | 25825233 |
| vector potential and population dynamics for amblyomma inornatum. | we studied the natural life cycle of amblyomma inornatum and its vector potential in south texas. this tick is distributed throughout south texas and most of central america. a. inornatum represented 1.91% of the ticks collected by carbon dioxide traps during a study of free-living ticks in the tamaulipan biotic province in south texas. the life cycle of a. inornatum in south texas showed a clear seasonal pattern consistent with one generation per year. nymphs emerged in the spring with a peak i ... | 2015 | 25881916 |
| Life cycle of Haemaphysalis doenitzi (Acari: Ixodidae) under laboratory conditions and its phylogeny based on mitochondrial 16S rDNA. | The paper investigated the life cycle of the hard tick Haemaphysalis doenitzi under laboratory conditions and its phylogeny based on mitochondrial 16S rDNA. The results revealed that the complete life cycle of H. doenitzi requires a mean duration of 109.6 days ranging from 91 to 137 days and the average prefeeding, feeding and premoulting periods of larvae, nymphs and females and the eggs hatching period are 18.7, 26.9, 38.9, and 25.1 days, respectively. In addition, the weight of engorged femal ... | 2011 | 22113780 |
