False. This is a critical distinction in clinical parasitology. Not all intestinal flagellates are pathogenic. Giardia lamblia is a well-established pathogen causing giardiasis. However, others are generally considered non-pathogenic commensals, meaning they live in the intestine without causing harm. Examples include: Chilomastix mesnili, Trichomonas hominis, Enteromonas hominis, and Retortamonas intestinalis. Finding these in a stool sample is usually an incidental finding and does not explain the patient's symptoms. They do not require specific antiparasitic treatment. The presence of these non-pathogens should prompt the search for other causes of the patient's illness. Therefore, identification and differentiation are essential to avoid unnecessary treatment.
