What is the life cycle of Isospora belli?
What is the life cycle of Isospora belli?
The sporulation time of this parasite’s egg is usually 1–4 days, and the entire life cycle takes about 9–10 days. The infective stage found in stool is the mature oocyst. The mature oocyst for Cystoisospora belli can remain infective in the environment for months.
What is isospora hominis?
Isospora hominis Human isosporiasis is caused by Isospora belli, which is a true member of the genus Isospora (187). Many early reports of human coccidiosis refer to infection with a parasite described as Isospora hominis.
What causes Isospora belli?
Cystoisosporiasis is an intestinal disease caused by the microscopic parasite Cystoisospora belli. This is the same parasite that used to be called Isospora belli. The parasite can be spread by ingesting food or water that was contaminated with feces (stool) from an infected person.
Can humans get isospora?
Isospora species infection of the gastrointestinal tract is common in dogs. Transmission to humans has not been clearly proven, but it remains possible, especially in the immunocompromised patient.
How is Isospora belli transmitted?
Which Toxoplasma life stage is infective to humans?

Where is isosporiasis found in the world?
Thomas N. Oeltmann, in Human Parasitology (Fifth Edition), 2019 Isospora belli, the causative agent of isosporiasis in humans, is endemic in South America, the Caribbean, Africa, and Southeast Asia. The infective stage is the sporulated oocyst containing two sporocysts, each with four sporozoites.
What is Cystoisospora belli?
The coccidian parasite, Cystoisospora belli, infects the epithelial cells of the small intestine, and is the least common of the three intestinal coccidia that infect humans. At time of excretion, the immature oocyst contains usually one sporoblast (more rarely two).
