Abstract
This article reports on the occurrence of M. moniliformis in a 2-year-old girl in Iran after a long time period from its last recorded occurrence. Diagnosis of the both the earlier human record, as well as the later one that we are discussing in this report, has not initially been established by routine stool examination. In this case, symptoms that may suggest small bowel disease or dysfunction were not significantly seen. The worm obtained from the child was identified as a female M. moniliformis, but how the child became infected is unknown.
