Since Lyme arthritis was first described in the United States, it
has now been reported in many countries of Europe. However, very few
strains of the causative bacterium, Borrelia burgdorferi, have been isolated from synovial samples. For this reason, different molecular direct typing methods were developed recently to assess which
species could be involved in Lyme arthritis in Europe. We developed a
simple oligonucleotide typing method with PCR fragments from the
flagellin gene of B. burgdorferi sensu lato, which is able
to differentiate seven different Borrelia species. Among 10 consecutive PCR-positive patients with Lyme arthritis from the
northeastern France, two species were identified in synovial samples:
B. burgdorferi sensu stricto in 9 cases and B. garinii in 1 case. Conversely, all B. burgdorferi
sensu lato species detected in 10 consecutive PCR-positive biopsies
from a second set of patients with erythema migrans from the same
geographical area were identified as either B. afzelii or
B. garinii (P < 0.001). These results indicate that B. burgdorferi sensu stricto is the principal
but not the only Borrelia species involved in Lyme
arthritis in northeastern France.
