Rats and mice were infected with Bacillus piliformis organisms at a dosage which resulted in clinical signs of Tyzzer's disease in gerbils. Although rats and mice did not show clinical signs of disease, rising antibody titers to B. piliformis were detected by enzyme-linked immunosorbent assay (ELISA) 2 to 6 weeks post-inoculation and remained at positive levels 11 weeks post-inoculation. Western blot analyses of sera from experimentally infected animals revealed banding patterns nearly identical to those obtained using hyperimmune serum. Results indicated that elevated ELISA titers reflected production of specific antibodies directed against antigens of B. piliformis. ELISA and Western blot analyses of naturally infected animals yielded similar results. These findings suggest that immunoassays such as ELISA can be used to detect subclinically infected rats and mice in the absence of clinical signs or histopathologic evidence of Tyzzer's disease.
