46Diagnosis
47Diagnosis in Humans
- Isolation of organism
- Blood, bone marrow, other tissues
- Serum agglutination test
- Fourfold or greater rise in titer
- Samples 2 weeks apart
- Immunofluorescence of organism in clinical
specimen - PCR
48Diagnosis
- No single titer of Brucella antibodies is always
"diagnostic" however, most cases of active
infection have titers higher than 1160 - False-negative reactions in the SAT can result
from a prozone phenomenon - False-positive reactions occasionally result from
cross-reactions with antibodies to Yersinia,
cholera, or tularemia
49Diagnosis
- False-negative and false-positive reactions can
be avoided by routinely diluting the serum beyond
1320. - Very rarely, the presence of so-called blocking
antibodies yields a negative reaction, blocking
substances can be identified by the Coombs test
or a blocking assay. - When agglutination tests are equivocal, the
Brucella enzyme-linked immunosorbent assay can be
definitive
