Blastocystis hominis er en vanlig protozoisk parasitt som finnes i tarmene og ofte påvises hos personer med gastrointestinale symptomer. Mens dens rolle i å forårsake sykdom fortsatt er omdiskutert, er den ofte knyttet til ulike fordøyelsesproblemer og identifiseres ofte i avføringsprøver over hele verden.
Blastocystis hominis is a microscopic single-celled organism found in the intestines of humans and a variety of animals. It’s one of the most common parasites detected in human fecal samples. The parasite has several subtypes, some of which are thought to be more likely to cause symptoms than others.
Blastocystis hominis is typically caused by ingesting food or water contaminated with the parasite. It can also be transmitted through direct person-to-person contact, particularly in settings with poor hygiene and sanitation practices. This protozoan parasite commonly causes gastrointestinal symptoms and is one of the most commonly identified parasites in human stool samples worldwide.
