These birds were evaluated for the presence of antibodies against Chlamydophila psittaci by complement fixation test and C.
Serology for H capsulatum, obtained for the evaluation of fever of unknown origin, revealed mycelial and yeast complement fixation titers of 1:512 with a positive M and H band on immunodiffusion.
The tests included anti-DNA, ANA (anti-nuclear antibodies) anti-parietal cells, rheumatoid factor, complement fixations and circulating immune complexes.
Complement fixation tests against ZIKV and YFV antigens confirmed these interpretations.
On a serum specimen obtained about 10 days after onset of symptoms, a complement fixation test was positive at 1:8, and immunodiffusion for IgM and IgG were both negative (Mayo Medical Laboratories, Rochester, MN).
EVALUATIONS/MEASUREMENTS: We defined a case by positive immunodiffusion serology, a [greater than or equal to] 4-fold titer rise in complement fixation between acute and convalescent sera, or positive urinary Histoplasma capsulatum (HC) antigen.
 Serologic tests, including complement fixation assay, enzyme-linked immunosorbent assay, and immunoblotting assay, are available from the Centers for Disease Control and Prevention and may be of benefit in the clinical evaluation.
