Abstract
BACKGROUND: The Molavi street archeological site south of Tehran accidentally provided a unique opportunity for paleoparasitological studies in Iran. A female skeleton was unearthed and evaluated to be 7000 years old. Soil samples were collected around the pelvic and sacrum bones. FINDINGS: Careful microscopic investigation of rehydrated soil samples revealed the presence of one Enterobius vermicularis egg attached to the skeleton sacral region. CONCLUSION: The present finding likely represents the oldest evidence of a human pinworm infection in Asia.
