tick-borne zoonotic bacteria in ticks collected from central spain.the prevalence of tick-borne and related bacteria infecting adult ticks in central spain was assessed by molecular methods. six areas were sampled monthly during a 2-year longitudinal study. a total of 1,038 questing and 442 feeding ticks, belonging to eight different species, were tested. the most abundant species were hyalomma lusitanicum (54% of captures), followed by dermacentor marginatus (23%) and rhipicephalus sanguineus (10%). four human pathogens, including seven rickettsia species, ana ...200919556569
prevalence of francisella tularensis and francisella-like endosymbionts in the tick population of hungary and the genetic variability of francisella-like agents.several new taxa belonging to the genus francisella have been described recently. the present study describes the prevalence of francisella tularensis and francisella-like endosymbionts (fle) in ticks collected from hungary from 2007 to 2009 and characterizes the genetic variability of fles. a total of 5402 ixodid ticks (ixodes ricinus, i. acuminatus, dermacentor marginatus, d. reticulatus, haemaphysalis inermis, h. concinna, h. punctata) were collected from vegetation and animal hosts and teste ...201323421891
environmental monitoring and surveillance of rodents and vectors for francisella tularensis following outbreaks of human tularemia in georgia.tularemia is a re-emerging bacterial zoonosis, broadly distributed across the northern hemisphere. in georgia, there is a history of human tularemia outbreaks dating back to the 1940s. in response to outbreaks, health officials initiated long-term field surveillance and environmental monitoring. the objective of our study was to obtain information from 57 years of field surveys to identify species that play a role in the occurrence francisella tularensis subsp. holarctica in the environment in g ...201526394283
analysis of pathogen co-occurrence in host-seeking adult hard ticks from serbia.past studies in serbia have reported concurrent infections of ixodes ricinus ticks with borrelia burgdorferi sensu lato genospecies, anaplasma phagocytophilum and francisella tularensis. as a step forward, this investigation included a broader range of microorganisms and five most common and abundant tick species in serbia. five tick species were identified (dermacentor marginatus, d. reticulatus, haemaphysalis punctata, h. concinna and i. ricinus) and analyzed for the presence of seven pathogen ...201322773070
tick species, tick-borne pathogens and symbionts in an insular environment off the coast of western france.insular environments provide ideal natural conditions to study disease ecology, especially emerging diseases, due to clear differentiation between local and long-distance transmission. such environments are of particular interest regarding tick-borne pathogens (tbp), since animal exchange with the mainland (along with any ticks they carry) is limited, and because such locations could lie on migratory routes for birds carrying ticks. therefore both tick species and tbp may display different preva ...201627622976
presence of an emerging subclone of francisella tularensis holarctica in ixodes ricinus ticks from south-western germany.the zoonotic disease tularaemia is caused by the bacterial pathogen francisella tularensis. although the causative agent is known for 100 years, knowledge of its enzootic cycles is still rudimentary. apart from tabanids and mosquitoes, hard ticks have been described as important vectors and potential reservoirs for f. tularensis. available data on the incidence of human tularaemia indicate an increase in cases in the federal state of baden-wuerttemberg. to determine whether ticks are involved in ...201323141103
molecular investigation of francisella-like endosymbiont in ticks and francisella tularensis in ixodid ticks and mosquitoes in turkey.this study was carried out to investigate the molecular prevalence of francisella-like endosymbionts (fles) and francisella tularensis in ticks (acari: ixodidae) and mosquitoes in turkey. genomic dna pools were constructed from a total of 1477 adult hard ticks of rhipicephalus (rh.) annulatus, rh. turanicus, rh. sanguineus, rh. bursa, haemaphysalis (hae.) parva, hae. sulcata, hyalomma marginatum marginatum, h. anatolicum anatolicum, h. anatolicum excavatum, h. detritum detritum, h. dromedarii, d ...201626741324
