    Impaired immune responses induced by Borreliae occur in reservoir and incidental hosts.  Persistence of Bb both in reservoir (murine) and incidental (primate) hosts is the norm and not the exception. The Lyme disease spirochete engages both in immune evasion and in active immune suppression. In particular, the ability of this pathogen to suppress humoral immunity and memory responses has been well-characterized in mice  [92-94]. We have performed an analysis of antibody responses to an unrelated vaccine antigen in primates infected with Borrelia. Our preliminary data  demonstrate that Borrelia infection can suppress acquired immune responses in a pathogen-independent fashion with variation in outbred hosts.
