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
In the present thesis consecutive patients, 231 with ECMA, 41 with ACA and 20 with facial palsy (Bell's palsy), have been studied. It has been shown that spirochetes, transmitted by the tick Ixodes ricinus, are involved in the etiology of ECMA and ACA. This has been shown through the isolation and
Lyme disease in children is studied in the light of questionnaires sent out twice to departments and divisions of pediatrics in Switzerland. Thirty-six serologically proven cases were collected. The 48 clinical signs attributed to Lyme disease involved the skin in 40%, the nervous system in 40%, and
The prevalence of different genospecies of Borrelia burgdorferi sensu lato in infected ticks could be a determinant for the risk of acquiring Lyme borreliosis (LB) and its clinical presentation. A total of 7373 ticks and 2761 samples from LB patients from the same area in southwest Germany were
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
Previous studies on cells of strains B31 isolated in the U.S.A. from Ixodes dammini and strain G25 isolated in Sweden from Ixodes ricinus, showed that their ultrastructure was similar, but not identical. For this reason the studies were extended to spirochetes isolated directly from patients with
Among 2403 ticks (Ixodes ricinus) tested in 1985 for Borrelia 328 (13.6%) were carriers (adults about 20%, nymphs about 10%, larvae about 1%). The highest prevalence of infected ticks was among adult ticks in the Isar region north of Munich (33.8%). Among 9383 persons whose serum had been examined
The presence of signs of joint involvement was investigated in 231 patients with erythema chronicum migrans Afzelius (ECMA), in 50 patients with acrodermatitis chronica atrophicans (ACA), in four patients with spirochete-induced facial palsy and in one patient with pericarditis and serologic
