Study Notes
Intestinal Amebiasis
- Primary clinical manifestation: Diarrhea or dysentery
- Characteristic of severe intestinal amebiasis: Presence of blood and mucus in stool
Entamoeba histolytica
- Trophozoites primarily found: In the large intestine, particularly in the cecum and ascending colon
- Primary organ involved in extraintestinal amebiasis: Liver
Free-Living Amebae
- Found in: Freshwater environments, such as ponds, lakes, and rivers
- Examples of opportunistic human pathogens: Acanthamoeba, Naegleria, and Balamuthia
Epidemiology
- Protozoa infection with the highest incidence in tropical and subtropical regions with poor sanitation and contaminated water: Amebiasis
- Average prevalence of infection for Entamoeba histolytica in these regions: 10%
Treatment
- Medication used to treat acute, fulminating amebiasis caused by Entamoeba histolytica: Metronidazole
Giardia lamblia
- Infection initiation: Ingestion of contaminated food or water containing cysts
- Method to limit the spread of enteric protozoal infections in developing countries: Improving sanitation and providing access to clean water
