title: Detection of Borrelia burgdorferi outer surface protein antibodies in wild white-tailed deer (Odocoileus virginianus) in New York and Pennsylvania, USA.
abstract: Borrelia burgdorferi differentially exhibits outer surface proteins (Osp) on its outer membrane, and detection of particular Osp antibodies in mammals is suggestive of the infection stage. For example, OspF is typically associated with chronic infection, whereas OspC suggests early infection. A fluorescent bead-based multiplex assay was used to test sera from New York and Pennsylvania white-tailed deer (Odocoileus virginianus) for the presence of antibodies to OspA, OspC, and OspF. OspF seroprevalence was significantly greater than both OspA and OspC seroprevalence for all study sites. OspA, OspC, and OspF seroprevalences were significantly greater in Pennsylvania deer than New York deer. The regional differences in seroprevalence are believed to be attributable to a heterogeneous Ixodes scapularis distribution. While most seropositive deer were solely OspF seropositive, deer concurrently OspC and OspF seropositive were the second most commonly encountered individuals. Simultaneous detection of OspF and OspC antibodies may occur when non-infected or chronically infected deer are bitten by an infected tick within a few months of blood collection, thereby inducing production of antibodies associated with the early stages of infection with B. burgdorferi.
