Protozoan Parasites Quiz

Overview of Protozoan Parasites: Trichomonas, Dientamoeba, and Chilomastix

• Trichomonas is a protozoan parasite that causes vaginitis and is transmitted through sexual contact or sharing of contaminated clothing and linens.
• Trichomonas can survive in moist clothing for up to one day and thrives in a slightly alkaline or acidic pH environment.
• Symptoms of trichomoniasis in females include itching, burning, and frothy discharge, while males are mostly asymptomatic.
• Diagnosis of trichomoniasis can be done through microscopy of urine or vaginal discharge in females and urine or prostatic and seminal fluid in males.
• Treatment for trichomoniasis involves oral metronidazole or acidic douches, but reinfection can occur immediately.
• Chilomastix is a non-pathogenic endocommensal protozoan parasite found in the cecum and large intestine of humans and other primates.
• Chilomastix is transmitted through ingestion of trophozoites in contaminated water and divides by binary fission.
• Diagnosis of chilomastix can be done through stool examination and identification of pear-shaped trophozoites with stiff rotary motility.
• Dientamoeba fragilis is a flagellate protozoan parasite that resides in the mucosal crypts of the large intestine and is often co-infected with enterobiasis.
• Diagnosis of dientamoeba fragilis can be done through identification of motile organisms with irregular and round shapes through microscopy.
• Treatment for dientamoeba fragilis involves iodoquinol taken three times a day for 20 days.
• Presence of chilomastix and dientamoeba fragilis indicates poor hygiene practices and sanitation.
