The ability of vaccination with recombinant OspA from six seroprotective
groups of Borrelia burgdorferi sensu lato to induce protection against
infection with homologous and other Lyme spirochetes was examined in
hamsters. Antisera generated against the OspA proteins of B. burgdorferi
sensu stricto S-1-10 and C-1-11 (seroprotective groups 1 and 2,
respectively), Borrelia afzelii BV1 (seroprotective group 4), and Borrelia
garinii LV4 (seroprotective group 5) were able to kill the homologous
spirochete in vitro but not other isolates. Surprisingly, antisera against
B. afzelii PKo (seroprotective group 6) and B. burgdorferi sensu lato LV5
(seroprotective group 3) OspA proteins were unable to kill the homologous
organism, although LV5 OspA antisera killed the heterologous isolates
S-1-10 and LV4. In vivo vaccination studies supported the in vitro
findings, confirming that vaccination with a single OspA protein does not
provide complete protection against challenge with all Lyme disease
spirochetes. In addition, OspA antibodies from some isolates may not
protect against the homologous isolate. The induction of protective
antibodies against other B. burgdorferi proteins may be necessary to insure
a comprehensive Lyme disease vaccine.
