balantidium coli size

7-177). As in amebiasis, symptomatology ranges from the asymptomatic carrier state; to chronic symptoms with intermittent diarrhea and constipation, abdominal pain, and weight loss; to a dysenteric form with blood and mucus in the stool and tenderness over the colon. Balantidium coliis the largest protozoan that parasitizes man. through contaminated food or water). Infection occurs when a host ingests a cyst, which usually happens during the consumption of contaminated.

Size, however, varies, with some balantidia being up to 200 m in length. Positive animals should be isolated and the infection appropriately treated. Transmission from nonhuman primates and rats may also occur. Organisms can occasionally be highlighted with Giemsa stain. What is Balantidium coli?. While this type of infection is uncommon in the United States, humans and other mammals can become infected with Balantidium coli by ingesting infective cysts from food and water that is contaminated by feces. In the trophozoite form, they can be oblong or spherical, and are typically 30 to 150 µm in length and 25 to 120 µm in width. Metronidazole 750 mg po tid for 5 days [4] or iodoquinol, 650 mg, three times a day for 20 days have also been used. The name derives from the pouch-like shape of the trophozoites (balanti-; Greek, bag or sac). Hyostrongylus rubidus of pigs is a gastric parasite that causes a thickening of the mucosa, with mucus accumulation and mucous cell hyperplasia and inflammation of the lamina propria by lymphocytes, plasma cells, and eosinophils. Both the trophozoite (usual size, 50-100 µm long and 40-70 µm wide) and cyst forms (usual size, 5-70 µm in diameter) can be found in clinical specimens. Protozoa are approximately 3-8 μm in diameter, representing various stages of development, including trophozoites and immature and mature schizonts.
