From three endemic locations of erythema chronicum migrans disease in North Rhine-Westphalia, Germany, we recovered 19 isolates of a spirochete from Ixodes ricinus ticks. The infection rate in adult ticks was 16 percent. The isolated spirochete is immunologically related to the Ixodes dammini spirochete, Borrelia duttoni, and Treponema pallidum. Using(More)
From ticks of the type Ixodes ricinus, 19 strains of a spirochete were isolated at three places of infection of erythema chronicum migrans disease. The spirochete was immunologically related to Borrelia duttoni, Treponema pallidum and Ixodes dammini spirochete, the causative organism of North American erythema chronicum migrans disease (Lyme disease).

Using indirect immunofluorescence, IgG antibodies against the recently detected Ixodes-ricinus-spirochaeta, which causes erythema chronicum migrans could be demonstrated in all 21 persons with acrodermatitis chronica atrophicans. Titers were from 1 : 64 to 1 : 1024, specific IgM antibodies were demonstrable in only 5 patients in a titer of 1 : 64. Even(More)
