Auf Fingerle würde ich gar nichts geben! Für den ist eh alles harmlos. Stimmt B. miyamotoi ist in Deutschland selten. Es ist aber auch selten, dass Leute so schwer erkranken wie viele hier im Forum, in sofern kann man nichts ausschließen. Es wird auch noch zig andere Borrelienstämme geben, die man bisher einfach nicht nachweisen kann, weil die nötigen Tests fehlen.

Prevalence of B. miyamotoi in Europe and the United States

I. ricinus ticks from the Czech Republic and Germany in Europe and I. scapularis and I. pacificus ticks from 5 states in the United States were screened for B. miyamotoi by PCR/ESI-MS. B. miyamotoi was found in all regions examined in varying degrees (Table 1) and in all 3 Ixodes species examined. Germany had a low incidence rate; only 4 of the 226 ticks tested were infected (1.8%). Incidence of B. miyamotoi infection of ticks from the Czech Republic varied by region and ranged from 0% to 3.2% with an average infection rate of 2%. In North America, the infection rates of ticks varied from 0% to 15.4%. All negative controls were negative and all positive controls were positive.

Abstract

Borrelia miyamotoi, a relapsing fever-related spirochete transmitted by Ixodes ticks, has been recently shown to be a human pathogen. To characterize the prevalence of this organism in questing Ixodes ticks, we tested 2,754 ticks for a variety of tickborne pathogens by PCR and electrospray-ionization mass spectrometry. Ticks were collected from California, New York, Connecticut, Pennsylvania, and Indiana in the United States and from Germany and the Czech Republic in Europe from 2008 through 2012. In addition, an isolate from Japan was characterized. We found 3 distinct genotypes, 1 for North America, 1 for Europe, and 1 for Japan. We found B. miyamotoi infection in ticks in 16 of the 26 sites surveyed, with infection prevalence as high as 15.4%. These results show the widespread distribution of the pathogen, indicating an exposure risk to humans in areas where Ixodes ticks reside.
