To determine whether the pathogenic variant of Lyme disease spirochetes, isolate A14S, is perpetuated in a particular reservoir-vector relationship, we screened vector ticks in various Central European sites for a related spirochete and determined its host association. A14S-like spirochetes infect numerous questing ticks in the Petite Camargue Alsacienne(More)
Bei 251 erlegten Feldhasen (Lepus europaeus Pallas 1778) aus 13 Untersuchungsgebieten der Oberrheinebene wurde der Befall mit Endoparasiten untersucht. 99,6 % aller Hasen waren von insgesamt 12 verschiedenen Parasitenarten (Eimeria semisculpta, E. robertsoni, E. leporis, E. europaea, E. townsendi, Cittotaenia denticulata, C. leuckarti, Protostrongylus(More)
To determine whether direct passage of spirochetes between co-feeding vector ticks contributes to the likelihood that the Lyme disease spirochete Borrelia afzelii will perpetuate in nature, we compared the effects of time and space on transmission efficiency between simultaneously feeding ticks. The likelihood of co-feeding transmission increases with(More)
To describe the contribution of garden dormice to the epizootiology of Lyme disease, we compared their reservoir capacity for these pathogens to that of other sympatric hosts. Garden dormice are trapped most abundantly during early spring and again during midsummer, when their offspring forage. They are closely associated with moist forests. Garden dormice(More)
The comeback of the Eurasian beaver (Castor fiber) throughout western and central Europe is considered a major conservation success. Traditionally, several subspecies are recognised by morphology and mitochondrial haplotype, each linked to a relict population. During various reintroduction programs in the 20th century, beavers from multiple source(More)
In Reply to Randolph and Gern: Although transmission between co-feeding vector ticks may perpetuate particular tick-borne viruses, this mode of transmission plays no role in the epizootiology of Lyme disease spirochetes (1,2). In their letter, Randolph and Gern defend their suggestion that tick-borne pathogens perpetuate effectively by direct passage from(More)
In recent years, swimmer's itch occurred in several ground water lakes dud excavation pools in sporadic or epidemic outbreaks in the upper Rhine valley. They were caused by Trichobilharzia szidati. The Public Health Offices in Offenburg and Freiburg have been dealing extensively with this problem. They were also requested to comment on the use of lakes(More)
