Comparison of an enzyme-linked immunosorbent assay to an indirect immunofluorescence assay for the detection of antibodies to Borrelia burgdorferi in the dog.
An enzyme-linked immunosorbent assay (ELISA) was compared to an indirect immunofluorescence assay (IFA) for detection of IgG antibodies to Borrelia burgdorferi in dog sera. The concordance of the two tests was 93.5% for sera from dogs from Maryland (n = 93), 98.0% for sera from dogs from North Carolina (n = 446), and 97.2% for the combined sample groups (n = 539). Twenty-five of the 27 samples with discordant or low positive results were tested, and showed immunoblot reactions to 1 to 10 different bands. Reaction patterns and intensity of the bands were quite variable, and did not explain a reason for the discordance.
