| [ecology of indigenious arbovirus in alsace. tick central european encephalitis. i.--complex ixodes ricinus--bank voles. ii.--study of bank voles population immunity. iii.--virologic results in bank voles population (author's transl)]. | i.--after showing that bank voles are parasited only by ixodes ricinus larvae, the authors attempt to found different factors (demographic, biometric, and sexual) who favor individual parasitism. the authors conclude to absent of anti tick immunity for this rodent specie. ii.--the search for anti-central european encephalitis antibodies (i.h.a.) are shown that 2 p. cent animals were immuns. yearly and monthly chronologies of antibodies apparition are shown, factors favoring the growth of specifi ... | 1979 | 538306 |
| prevalence of borrelia burgdorferi sensu lato and anaplasmataceae members in ixodes ricinus ticks in alsace, a focus of lyme borreliosis endemicity in france. | due to the high lyme borreliosis incidence in alsace, in northeastern france, we investigated in 2003-2004 three cantons in this region in order to determine the density of ixodes ricinus ticks infected by borrelia burgdorferi sensu lato and anaplasmataceae. the peak density of nymphs infected by b. burgdorferi sensu lato at munster and guebwiller, where the disease incidence was high, was among the highest reported in europe (105 and 114 per 100 m(2), respectively). in contrast, the peak densit ... | 2006 | 16598024 |
| [epidemiology of lyme borreliosis and neuroborreliosis in france]. | lyme borreliosis (lb) is a systemic disease called neuroborreliosis (nb) when neurological symptoms are pre-eminent. lb is a zoonosis caused by borrelia bacteria transmitted by ixodes tick-bite. because of the absence of a national registry, epidemiology of lb in france is not well known. moreover, diagnosis of nb may be difficult because of the various clinical forms. acute meningoradiculitis is the most common presentation, but pauci-symptomatic meningitis, encephalitis, myelitis, polyneuropat ... | 2009 | 19447458 |
| [some demographic datas from ixodes ricinus linné: vector of a virus strain of central european encephalitis in alsace (author's transl)]. | this work shows the montly variation in the density and stage composition of the population of the tick ixodes ricinus in the rhine forest. some factors influencing this variation are analysed. these include the locality of egg-laying and of down localisation and the main climatic variables. we also try to link these ecological data with the strains of central european encephalitis virus isolated from this arthropod. | 1977 | 618028 |
