 Treatment via amphotericin B (lowly effective)  Diagnosis via negative gram stain and motile amoeba in CSF under microscopy, CSF has high PMN, low glucose, and high protein (seen via lumbar puncture)

 Disease includes rapidly fatal meningoencephalitis with no corneal infection (only mature amoeba are present, not cysts)  Transmission via swimming in fresh water lakes, specifically enters through the nasal passage and pierces the cribriform plate into the CSF  Treatment via metronidazole (concomitantly for both partners)  Diagnosis via highly motile trophozoites on wet mount prep of vaginal discharge or urine, “strawberry cervix”  Disease includes foul-smelling, green vaginal discharge, dysuria, pruritis, and increased vaginal secretions in females males are asymptomatic  Diagnosis via stool microscopy and acid-fast positive (shows ruby-gem shaped).

 Disease includes severe diarrhea in immunocompromised patients.  Transmission via fecal-oral route – contaminated raspberries.  Treatment via nitazoxanide in normal hosts and nitazoxanide or paromomycin  azithromycin in immunocompromised prophylaxis via filtration of city water suppliesĬyclospora cayetanesis & Isospora belli  Diagnosis via oocysts on acid fast stain – appear amethyst shape and color with four motile sporozoites  Disease includes watery diarrhea in normal hosts and severe, protracted diarrhea in immunocompromised hosts  Transmission via oocysts in water – common in municipal water sources and daycare centers  Treatment via metronidazole prophylaxis via sanitation  Diagnosis via multinucleated “kite-shaped” trophozoites or cysts in stool  Disease includes giardiasis (bloating, flatulence, and steatorrhea)

 Transmission via fecal-oral route, cysts in water – common in campers drinking water from a “clear” mountain stream  Treatment via metronidazole intestinal cysts via paromomycin and iodoquinol  Diagnosis via trophozoites or cysts in stool (active disease if only trophozoites, asymptomatic carrier if both are present)  Disease includes amebiasis (dysentery, liver abscess with “anchovy paste” exudate with right upper quadrant tenderness, and “flask-shaped” colonic ulcerations,)  Transmission via fecal-oral transmission, cysts in water Trophozoite for protection and motility, respectively.Įntamoeba histolytica – Entering the Historical Dig Protozoa are eukaryotic cells with both an ectoplasm and endoplasm, able to ingest food via mouth or endocytosis, reproduce both asexually and sexually, and transition between cyst and
