The laboratory diagnosis of Lyme borreliosis, the most prevalent vector-
borne disease in the United States and endemic in parts of Europe and Asia,
is currently based on serology with known limitations. Direct demonstration
of Borrelia burgdorferi by culture may require weeks, while enzyme-linked
immunosorbent assays for antigen detection often lack sensitivity. The
development of the PCR has offered a new dimension in the diagnosis.
Capable of amplifying minute amounts of DNA into billions of copies in just
a few hours, PCR facilitates the sensitive and specific detection of DNA or
RNA of pathogenic organisms. This review is restricted to applications of
PCR methods in the diagnosis of human B. burgdorferi infections. In the
first section, methodological aspects, e.g., sample preparation, target
selection, primers and PCR methods, and detection and control of inhibition
and contamination, are highlighted. In the second part, emphasis is placed
on diagnostic aspects, where PCR results in patients with dermatological,
neurological, joint, and ocular manifestations of the disease are
discussed. Here, special attention is given to monitoring treatment
efficacy by PCR tests. Last, specific guidelines on how to interpret PCR
results, together with the advantages and limitations of these new
techniques, are presented.
