| [ecology and distribution of the tick, ixodes lividus, in karelia (ixodidae)]. | the territory of karelia was investigated from 62 degrees to 66 degrees n. in the nests of riparia riparia the tick ixodes lividus at all active phases of its development was first found. on the northern border of its distribution area the species shows a tendency to hibernate at the phases of nymph, female and male. this ability has favoured to a considerable extent the advancement of the species into the northern latitudes up t degrees 66 degrees n. | 1979 | 158740 |
| [kama, a new virus (flaviviridae, flavivirus, tiulenii antigenic group), isolated from ixodes lividus ticks]. | three identical strains of a new virus kama (flaviviridae, flavivirus, tyuleny antigenic group) were isolated from ixodes lividus roch, obligate parasites of riparia riparia l. the ticks were collected in june, 1990 in tatarstan on the islands in the basin of the kama river. the strains were examined under electron microscope and by serological tests (neutralization, complement fixation, hemagglutination inhibition, and indirect immunofluorescence). the virus is antigenically related but not ide ... | 1998 | 9606874 |
| detection of spotted fever group rickettsia spp. from bird ticks in the u.k. | migratory birds are known to play a role in the long-distance transportation of microorganisms. to investigate whether this is true for rickettsial agents, we undertook a study to characterize tick infestation in populations of the migratory passerine bird riparia riparia (passeriformes: hirundinidae), the sand martin. a total of 194 birds were sampled and ticks removed from infested birds. the ticks were identified as female ixodes lividus (acari: ixodidae) using standard morphological and mole ... | 2010 | 20546129 |
| tick surveillance in great britain. | the ability for public/veterinary health agencies to assess the risks posed by tick-borne pathogens is reliant on an understanding of the main tick vector species. crucially, the status, distribution, and changing trends in tick distribution and abundance are implicit requirements of any risk assessment; however, this is contingent on the quality of tick distribution data. since 2005 the health protection agency has promoted an enhanced tick surveillance program. through engagement with a variet ... | 2011 | 20849277 |
| global ecology and epidemiology of borrelia garinii spirochetes. | lyme borreliosis (lb) is a tick-transmitted infectious disease caused by borrelia burgdorferi sensu lato (s. l.). in europe, three different borrelia species are the main causative agents of lb: b. burgdorferi sensu stricto (s.s.), borrelia afzelii, and borrelia garinii. the latter depends heavily on birds as its main reservoir hosts. in fact, birds can act both as biological carriers of borrelia and transporters of infected ticks. the seasonal migration of many bird species not only aid in the ... | 2011 | 22957111 |
| ticks of poland. review of contemporary issues and latest research. | the paper presents current knowledge of ticks occurring in poland, their medical importance, and a review of recent studies implemented in the polish research centres on ticks and their significance in the epidemiology of transmissible diseases. in the polish fauna there are 19 species of ticks (ixodida) recognized as existing permanently in our country: argas reflexus, argas polonicus, carios vespertilionis, ixodes trianguliceps, ixodes arboricola, ixodes crenulatus, ixodes hexagonus, ixodes li ... | 2012 | 23444797 |
| interactions between tick and transmitted pathogens evolved to minimise competition through nested and coherent networks. | natural foci of ticks, pathogens, and vertebrate reservoirs display complex relationships that are key to the circulation of pathogens and infection dynamics through the landscape. however, knowledge of the interaction networks involved in transmission of tick-borne pathogens are limited because empirical studies are commonly incomplete or performed at small spatial scales. here, we applied the methodology of ecological networks to quantify >14,000 interactions among ticks, vertebrates, and path ... | 2015 | 25993662 |
| nested coevolutionary networks shape the ecological relationships of ticks, hosts, and the lyme disease bacteria of the borrelia burgdorferi (s.l.) complex. | the bacteria of the borrelia burgdorferi (s.l.) (bbg) complex constitute a group of tick-transmitted pathogens that are linked to many vertebrate and tick species. the ecological relationships between the pathogens, the ticks and the vertebrate carriers have not been analysed. the aim of this study was to quantitatively analyse these interactions by creating a network based on a large dataset of associations. specifically, we examined the relative positions of partners in the network, the phylog ... | 2016 | 27662832 |
| spatial disaggregation of tick occurrence and ecology at a local scale as a preliminary step for spatial surveillance of tick-borne diseases: general framework and health implications in belgium. | the incidence of tick-borne diseases is increasing in europe. sub national information on tick distribution, ecology and vector status is often lacking. however, precise location of infection risk can lead to better targeted prevention measures, surveillance and control. | 2013 | 23800283 |
| update on tick-borne rickettsioses around the world: a geographic approach. | tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus rickettsia. these zoonoses are among the oldest known vector-borne diseases. however, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. several species of tick-borne rickettsiae that wer ... | 0 | 24092850 |
| bird ticks in hungary reflect western, southern, eastern flyway connections and two genetic lineages of ixodes frontalis and haemaphysalis concinna. | birds play an important role in short- and long-distance transportation of ticks and tick-borne pathogens. the aim of the present study was to provide comprehensive information on the species and genetic diversity of ixodid ticks transported by migratory and non-migratory bird species in central europe, and to evaluate relevant data in a geographical, as well as in an ecological context. | 2016 | 26912331 |

| exposure to ectoparasites increases within-brood variability in size and body mass in the sand martin. | parasites often have detrimental effects on their hosts, and only host individuals able to cope with parasitism are likely to display induced or genetic resistance. hosts may respond to parasitism by differential investment in offspring depending on their ability to cope with parasitism, because offspring that perform better than their siblings are themselves likely to have superior induced or genetic resistance. we tested whether nestlings of the highly colonial sand martin riparia riparia were ... | 2000 | 24595831 |
| cost of parasitism and host immune defence in the sand martin riparia riparia: a role for parent-offspring conflict? | parent-offspring conflict may arise because the lifetime reproductive success of the parent is more influenced by its life span than by reproductive success during a particular reproductive event, while the fitness of an offspring depends firstly on its own survival as a juvenile and only subsequently on its own reproductive success. the naive immune system of young animals may allow offspring to be much more affected by parasites than their parents, and thus cause an initial asymmetry in a pote ... | 1999 | 28308163 |
| isolated populations of ixodes lividus ticks in the czech republic and belgium host genetically homogeneous rickettsia vini. | in the last two decades, the advent of molecular methods has revealed a remarkable diversity of rickettsiae (rickettsiales: rickettsiaceae) in invertebrates. several species of these obligate intracellular bacteria are known to cause human infections, hence more attention has been directed towards human-biting ectoparasites. a spotted fever group rickettsia sp. was previously detected in ixodes lividus ticks (ixodidae) associated with sand martins (hirundinidae: riparia riparia). in order to ide ... | 2018 | 29373306 |
