Further studies on fecal parasites in antiquity

This is a continuation study of the survival of antigenic material over the centuries using mummified human remains from the Andean area of South Amer ica. The fluorescent antibody kit from Meridian Diagnostics (Cincinnati, OH ) was used to identify some Cryptosporidium species and Giardia species fou nd in feces from the intestines of mummies 500 to 3,000 years old. The spec imens that were positive by direct visualization using fluorescent antibody were then tested with an enzyme-linked immunosorbent assay reaction using a Meridian kit just released on the market. Since all of the feces used wer e formed, it would seem that the organisms found were from carriers rather than active cases of disease. Similar fecal specimens were shown to harbor antigens from Helicobacter pylori almost 3, 000 years old.
