lyme borreliosis incidence in two french departments: correlation with infection of ixodes ricinus ticks by borrelia burgdorferi sensu lato.we conducted a prospective study to estimate the lyme borreliosis incidence in two rural french departments, meuse and puy-de-dôme. concurrently, we investigated the prevalence of ticks infected with borrelia burgdorferi sensu lato (sl) and anaplasma phagocytophilum. the incidence of lyme borreliosis decreased from 156 to 109/100,000 inhabitants in meuse and from 117 to 76/100,000 inhabitants in puy-de-dôme in 2004 and 2005, respectively, corresponding to a decrease in the density of ixodes rici ...200717979533
[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 ...200919447458
comparison of western blot and microimmunofluorescence as tools for lyme disease seroepidemiology.sera from a population of 212 farmers of the puy de dôme (midlands of france) who are in close contact with ixodes ricinus, the vector of lyme disease in europe, and sera from 100 urban blood donors from the nearly city of clermont ferrand were examined by microimmunofluorescence (mif) for antibodies reacting with borrelia burgdorferi. the results showed a higher seroprevalence of igg > 1/100 in farmers (25%) than in blood donors (10%). using western blot with antibody at a 1/200 dilution, and r ...19938405312
