What Is The Reservoir Host Of B Coli?

Hosts. Swine are the primary reservoir hosts. Humans can also be reservoirs, and other potential animal hosts include rodents and nonhuman primates.

What is the mode of transmission of B coli?

How is Balantidium coli transmitted? Balantidium coli is transmitted through the fecal-oral route. Humans can become infected by eating and drinking contaminated food and water that has come into contact with infective animal or human fecal matter.

What is the accidental host of B coli? Balantidium coli is the largest and the only ciliate protozoan that infects humans, who are typically accidental hosts after fecal/oral exposure. B. coli has a worldwide distribution, and pigs are the reservoir hosts.

What is the definitive host for Balantidium coli?

Balantidium (=Neobalantidium) (=Balantioides) coli, a large ciliated protozoan, is the only ciliate known to be capable of infecting humans. It is often associated with swine, the primary reservoir host.

What enzyme is produced by B coli that causes an intestinal ulcer?

Although Balantidium coli usually resides in the lumen of its host, trophozoites can invade the mucosa of the large intestine (cecum and colon) and cause ulcerations. The parasite secretes a substance called hyaluronidase enzyme, which helps degrade intestinal tissue and facilitates penetration of the mucosa.

Which one of the following is the largest protozoan parasite in humans?

Balantidiasis (also known as balantidiosis) is defined as large-intestinal infection with Balantidium coli, which is a ciliated protozoan (and the largest protozoan that infects humans).

Is coccidiosis a bacterial disease?

Coccidiosis is a common protozoan disease in domestic birds and other fowl, characterized by enteritis and bloody diarrhoea. The intestinal tract is affected, with the exception of the renal coccidiosis in geese.

Is Balantidium coli A Ciliate?

Balantidium (=Neobalantidium) (=Balantioides) coli, a large ciliated protozoan, is the only ciliate known to be capable of infecting humans. It is often associated with swine, the primary reservoir host.

What are the stages of Balantidium coli?

Balantidium coli has 2 developmental stages: a trophozoite stage and a cyst stage. (See Morphology and Transmission for further descriptions of the stages.)

What is the life cycle of Balantidium coli?

Life Cycle of Balantidium coli. Balantidium coli has 2 developmental stages: a trophozoite stage and a cyst stage. (See Morphology and Transmission for further descriptions of the stages.) The cyst is the infective stage of Balantium coli life cycle.

How is Balantidium coli treated?

Treatment. Three medications are used most often to treat Balantidium coli: tetracycline, metronidazole, and iodoquinol. Tetracycline*: adults, 500 mg orally four times daily for 10 days; children ≥ 8 years old, 40 mg/kg/day (max. 2 grams) orally in four doses for 10 days.

Who has higher risk of getting Balantidiasis?

Risk factors for balantidiasis include contact with pigs, handling fertilizer contaminated with pig excrement, and living in areas where the water supply may be contaminated by the excrement of infected animals. Poor nutrition, achlorhydria, alcoholism, and immunosuppression may also be contributing factors.

What is a primary symptom of giardiasis?

Giardia infection is an intestinal infection marked by stomach cramps, bloating, nausea and bouts of watery diarrhea. Giardia infection is caused by a microscopic parasite that is found worldwide, especially in areas with poor sanitation and unsafe water.

What are intestinal protozoa?

Nonpathogenic intestinal protozoa are single-celled parasites commonly found in the intestinal tract but never associated with illness. They do not harm the body, even in people with weak immune systems.

How does Giardia affect the human body?

Giardiasis (jee-are-DYE-uh-sis) is caused by the microscopic Giardia parasite. The parasite attaches itself to the lining of the small intestines in humans, where it causes diarrhea and interferes with the body’s absorption of fats and carbohydrates from digested foods.

What is Balantidiasis disease?

Balantidiasis is a rare intestinal infection caused by the bacterium, Balantidium coli, a single celled parasite (ciliate protozoan) that frequently infects pigs but on occasion (rarely) infects humans.
