Clinical characteristics of
Lyme disease (LD) course in children have been studied. Altogether 86 patients were examined. Serodiagnosis was made in patients basing on indirect immunofluorescence and enzyme immunoassay with LD agent antigens. Erythema–free forms, combination of mite-borne Borrelia infection with tick-borne encephalitis were detected. Two clinicoimmunological LD variants were verified: seropositive and seronegative mite-borne Borrelia infection with typical clinical manifestations. The
disease took a benign course responsive to antibiotics in combined treatment of neuromuscular lesions.
