SUMMARYBorrelia burgdorferiisolates were obtained fromIxodes ricinusfrom three sites in Switzerland. They were examined by SDS-PAGE and immunoblotting. The phenotypes, in respect of three outer surface proteins (Osp), differed between the sites of collection. In site 1, most isolates had an OspA of 31 kDa and an OspB of 34 kDa: in site 2, isolates presenting an OspA of 33 kDa dominated and in site 3, the isolates with an OspA of 32 kDa and an OspB of 35 kDa were most frequent. This distribution differed significantly. About half of the isolates from sites 1 and 3 reacted with anti-OspA monoclonal antibody H5332 compared to 29% from site 2. Site 1 isolates reacted significantly more frequently (81 %) with another anti-OspA monoclonal antibody LA-31 than isolates from site 3 (P< 0·0001). These findings have implications for the epidemiology of Lyme borreliosis, for the further development of serodiagnostic reagents and for the development of a vaccine.

ABSTRACT Persistence of borreliae within the vertebrate host depends on the fate of interactions between the spirochetes and target cells. The present work demonstrates the direct binding of the Borrelia burgdorferi outer surface proteins OspA and OspB to CR3 and that this binding is independent of iC3b.

In the 20 years since the first agent of Lyme disease was discovered, much interest has focused on the possible biological roles of a few outer surface proteins (Osps) in the alternating life cycle that includes ticks and vertebrate hosts. Two major proteins, OspA and OspC, are differentially regulated by the spirochaete Borrelia burgdorferi during the several days when ticks feed. The reciprocal decrease in OspA with the rapid up-regulation of OspC by the spirochaetes when ticks are feeding suggests that OspA aids in spirochaete attachment while OspC assists in the dissemination of spirochaetes from tick to vertebrate. Future experiments in ticks with mutant spirochaetes that lack these proteins should clarify the speculative functions currently given to these proteins.
