Use of recombinant antigens of Borrelia burgdorferi and Anaplasma phagocytophilum in enzyme-linked immunosorbent assays to detect antibodies in white-tailed deer.
2004
Serum samples obtained from white-tailed deer (Odocoileus virginianus) in Connecticut (n=218) and South Carolina (n=20) (USA) during the period 1992–2002 were analyzed for antibodies to whole-cell or recombinant antigens (i.e., fusion proteins) of Borrelia burgdorferi sensu stricto and Anaplasma phagocytophilum, etiologic agents of Lyme borreliosis and granulocytic ehrlichiosis, respectively. In enzyme-linked immunosorbent assays (ELISAs) with whole-cell B. burgdorferi, the overall seropositivity rate for Connecticut (53%) exceeded that for South Carolina (30%). In separate tests of seven recombinant antigens of B. burgdorferi by an ELISA, seroprevalence for the VlsE antigen was highest (48%) in Connecticut followed by outer surface protein (OspF) (21%), whereas serum reactivities to the protein (p) 41-G antigen (55%) and VlsE (25%) were most frequent for South Carolina sera. In analyses for antibodies to the recombinant protein (p) 44 antigen of A. phagocytophilum, seroprevalences of 52% and 25% were rec...
