| pubmed-article:11760158 | pubmed:abstractText | The avidity indices of Borrelia burgdorferi-specific IgG antibodies were estimated using ELISA in sera from patients with different stages of Lyme disease. In addition, sera from healthy students with proof of borrelial-specific IgG antibodies from standard serology were tested. Low avidity indices were detected predominantly in sera from patients with early-stage Lyme disease [erythema migrans (EM); n = 25]. High avidity indices were found in healthy students (n = 72) and in most of the patients with neuroborreliosis (NB; n = 44) and chronic late-stage Lyme disease [acrodermatitis chronica atrophicans (ACA); n = 36]. In conclusion, early-stage Lyme disease (EM) could be differentiated from advanced and chronic stages (NB, ACA) and from "seropositive" healthy persons using avidity determination in the majority of patients in this study. | lld:pubmed |
