Insights

A rare Hymenolepis diminuta infection in a child was successfully treated with praziquantel. Phylogenetic analysis confirmed the tapeworm

Area of Science:

  • Medical Parasitology
  • Molecular Epidemiology

Background:

  • Hymenolepis diminuta (rat tapeworm) infections are uncommon in humans, particularly in children.
  • Guilan Province, Iran, is a region where parasitic infections require ongoing surveillance.

Observation:

  • A two-year-old boy presented with anorexia, weight loss, weakness, and disturbed sleep.
  • Stool examination confirmed a Hymenolepis diminuta infection by identifying numerous parasite eggs.

Findings:

  • Successful treatment of Hymenolepis diminuta infection was achieved with a single oral dose of praziquantel.
  • Phylogenetic analysis of the cytochrome c oxidase subunit 1 (Cox1) gene revealed 97.4-99.2% similarity to other Hymenolepis diminuta isolates in GenBank.

Implications:

  • This case highlights the importance of reporting Hymenolepis diminuta infections for better epidemiological understanding.
  • Effective treatment and molecular characterization aid in controlling this neglected parasitic disease.
