*Reactivity to either outer surface protein C (OspC) alone or to 2 antigens was required for a positive IgM response.
†Reactivity to >2 antigens was required for a positive IgG response. Full reactivity to an antigen is indicated by 4 points.
‡Every serum sample was tested at a dilution of 1/64. ++, strongly positive; +, positive.
§Samples that showed a positive (+) result were further tested at dilutions of 1:128 and 1:256.
