A collection of 104-fecal specimens from 45 patients with hepatitis A, 14 patients with hepatitis B, 10 patients with non-A, non-B hepatitis, 6 patients with diseases other than hepatitis, and 18 healthy adults were studied for the presence of secretory immunoglobulin A and immunoglobulin M to hepatitis A virus by solid-phase enzyme-linked immunosorbent assay and immune electron microsopy. Specific fecal antibody was found only in patients with hepatitis A. Of 54 specimens from patients with hepatitis A, only 10 (18.5%) possessed detectable levels of fecal antibody, and each of these was collected within 10 days from the onset of dark urine. All 10 fecal specimens contained hepatitis A-speci..
