| first survey on hard ticks (ixodidae) collected from humans in romania: possible risks for tick-borne diseases. | the importance of studies on the diversity of ticks attacking humans resides mostly in the relatively highly-specific tick-pathogen associations. human tick bites are commonly reported worldwide but removal of ticks from patients is rarely followed by specific identification of the ticks, leaving to some degree of hazard the preventive treatment of possible associated diseases. a total number of 308 ticks were collected between april and june 2010 from 275 human patients who voluntarily presente ... | 2010 | 21161719 |
| hemelipoglycoprotein from the ornate sheep tick, dermacentor marginatus: structural and functional characterization. | tick carrier proteins are able to bind, transport, and store host-blood heme, and thus they function also as antioxidants. nevertheless, the role of carrier proteins in ticks is not fully understood. some of them are found also in tick males which do not feed on hosts to such an extent such as females (there are differences in male feeding in different tick species) and thus they are not dealing with such an excess of heme; some of the carrier proteins were found in salivary glands where the pro ... | 2011 | 21214898 |
| growth of coxiella burnetii in the ixodes scapularis-derived ide8 tick cell line. | q fever, a zoonotic disease, is caused by a gram-negative intracellular bacterium, coxiella burnetii. although normally transmitted during exposure to infectious aerosols, c. burnetii is also found in arthropod vectors. in the environment, ticks are thought to play a crucial role in bacterial maintenance and transmission by infecting various mammalian species. however, the nature of the pathogen-tick relationship is not well defined. to determine c. burnetii's interactions with a cultured tick c ... | 2011 | 21254834 |

| tick-borne encephalitis virus in dogs - is this an issue? | abstract: the last review on tick-borne encephalitis (tbe) in dogs was published almost ten years ago. since then, this zoonotic tick-borne arbovirus has been geographically spreading and emerging in many regions in eurasia and continues to do so. dogs become readily infected with tbe virus but they are accidental hosts not capable to further spread the virus. they seroconvert upon infection but they seem to be much more resistant to the clinical disease than humans. apart from their use as sent ... | 2011 | 21489255 |

Most isolates from Western Europe are assigned to the B.Br.FTNF002-00 group, whereas most isolates ... | 2011 | 21682874 |
| toward an understanding of the perpetuation of the agent of tularemia. | the epidemiology of tularemia has influenced, perhaps incorrectly skewed, our views on the ecology of the agent of tularemia. in particular, the central role of lagomorphs needs to be reexamined. diverse observations, some incidental, and some that are more generally reproducible, have not been synthesized so that the critical elements of the perpetuation of francisella tularensis can be identified. developing a quantitative model of the basic reproduction number of f. tularensis may require sep ... | 2011 | 21687803 |
| detection of new francisella-like tick endosymbionts in hyalomma spp. and rhipicephalus spp. (acari: ixodidae) from bulgaria. | we report on the identification of two new francisella-like endosymbionts (fles) found in three different tick species from bulgaria. the fles were characterized by 16s rrna and tul4 gene sequencing and seem to lack the molecular marker rd1. these two new taxa seem to be facultative secondary endosymbionts of ticks. | 2011 | 21705542 |

| prevalence of coxiella burnetii and rickettsia spp. in ticks and rodents in southern germany. | coxiella burnetii, the causative agent of q fever, and rickettsia spp. are bacterial pathogens that can be transmitted by ticks of the genus dermacentor (i.e., dermacentor marginatus and d. reticulatus). in germany, the occurrence of these ticks is currently limited to few areas. however, due to increasing temperatures, these vectors will likely extend their distribution in the future, and c. burnetii and rickettsia spp. might spread with them. to assess the prospective risk of human infections ... | 2010 | 21771522 |
| coinfections of rickettsia slovaca and rickettsia helvetica with borrelia lusitaniae in ticks collected in a safari park, portugal. | borrelia and rickettsia bacteria are the most important tick-borne agents causing disease in portugal. identification and characterization of these circulating agents, mainly in recreational areas, is crucial for the development of preventive measures in response to the gradually increasing exposure of humans to tick vectors. a total of 677 questing ticks including dermacentor marginatus, rhipicephalus sanguineus, ixodes ricinus, hyalomma lusitanicum, h. marginatum, and haemaphysalis punctata we ... | 2010 | 21771525 |
| detection of coxiella burnetii in complex matrices by using multiplex qpcr during a major q fever outbreak in the netherlands. | q fever, caused by coxiella burnetii, is a zoonosis with a worldwide distribution. a large rural area in the southeast of the netherlands was heavily affected by q fever between 2007 and 2009. this initiated the development of a robust and internally controlled multiplex qpcr assay for detection of c. burnetii dna in veterinary and environmental matrices on suspected q fever affected farms. the qpcr detects three c. burnetii targets (icd, com1 & is1111), and one bacillus thuringiensis internal c ... | 2011 | 21784920 |

| 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.

| First transcriptome of the testis-vas deferens-male accessory gland and proteome of the spermatophore from Dermacentor variabilis (Acari: Ixodidae). | Ticks are important vectors of numerous human diseases and animal diseases. Feeding stimulates spermatogenesis, mating and insemination of male factors that trigger female reproduction. The physiology of male reproduction and its regulation of female development are essentially a black box. Several transcriptomes have catalogued expression of tick genes in the salivary glands, synganglion and midgut but no comprehensive investigation has addressed male reproduction and mating. Consequently, a ne ... | 2011 | 21949745 |
| Hard ticks (Ixodidae) in Romania: surveillance, host associations, and possible risks for tick-borne diseases. | Ticks and tick-borne diseases represent a great concern worldwide. Despite this, in Romania the studies regarding this subject has just started, and the interest of medical personnel, researchers, and citizens is increasing. Because the geographical range of many tick-borne diseases started to extend as consequences of different biological and environmental factors, it is important to study the diversity of ticks species, especially correlated with host associations.
