AB A new enzyme-linked-immunosorbent assay (ELISA) for the detection of
antibodies to feline immunodeficiency virus was compared with previously
described ELISAs. Serum samples from 184 infected or uninfected cats
were tested using a whole virus lysate kit and ELISAs based on
recognition of one of two synthetic peptides (P237 and P253) localized
in the transmembrane domain of the viral envelope. The whole virus
lysate commercial kit led to the detection of 6% false positive and 4.3%
false negative sera. The ELISA based on peptide P253 gave no false
positive result and failed to detect only one serum that was
subsequently shown to be positive by radio-immunoprecipitation assay. A
sandwich-ELISA test using Galanthus nivalis agglutinin, a lectin that
specifically binds terminal mannose groups of the envelope proteins was
used as a confirmatory test for equivocal results with peptide ELISA and
gave similar results. This study indicates that recognition of P253
could serve as a sensitive and specific test for the diagnosis of
seropositivity to feline immunodeficiency virus, and moreover that the
Galanthus nivalis ELISA could be useful in equivocal cases as a
confirmatory test.
