Blastocystis

Blastocystis

(blas'tō-sis'tis),
A genus of yeastlike parasites in the digestive tract of mammals; generally considered nonpathogenic. Its relationship to fungi is now being questioned owing to protozoan characteristics, such as lack of cell walls, a membrane-bound central body, pseudopod activity, protozoan type of Golgi apparatus and mitochondria, and reproduction by sporulation or binary fission rather than by budding.

With regard to this subject, most focus has been on Blastocystis. There is a relationship between a richer bacteria content and the presence of Blastocystis, and as in patients with IBD, Bacteroidetes and Clostridium IX have been determined to be decreased in the microbiota of Blastocystis positive patients (11).
Blastocystis is a single-celled parasite that is usually transferred by fecal-oral transmission and also affects the intestinal tract.
The examinations found the presence of the following parasites: Giardia intestinalis, Blastocystis hominis, Enterobius vermicularis, Hymenolepis nana, Ascaris lumbricoides, and Trichocephalus trichiurus (Table 3).
