ABSTRACT

Giardiasis caused by Giardia duodenalis is one of the leading causes of gastroenteritis, especially in developing countries. The patients harbouring this may not recover if metronidazole resistant is there. We present a case of 2-year-old girl on chemotherapy for metastatic para meningeal rhabdomyosarcoma. She had 15 days history of persistent diarrhea of foul-smelling loose stools, without fever. Light microscopy of stool wet mounts revealed Giardia duodenalis. The patient was managed with nitazoxanide after metronidazole proved ineffective clinically. This case highlights the importance of timely diagnosis and management of infectious diseases and rising antimicrobial resistance among parasites.
