Blastocystis hominis is a protozoan microorganism which may or may not cause disease in people. In a study published in 1988, 11 people with this organism in their stools who had diarrhea-like symptoms were studied. Those authors reviewed other reports and concluded there was no convincing proof that this organism caused disease in humans. Whether this is true in individuals who have some type of immunodeficiency is less clear.
Causes & Development Symptoms may be caused by infection with other parasitic organisms, bacteria, or viruses. The oral-fecal route is suspected, and it has been called 'the hippie disease', because it is more likely to occur in crowded and unsanitary conditions. The moment your body picks up a little, it may not be able to affect you.
Treatment & Prevention Blastocystis is difficult to eradicate. These treatments can be used in combination, but may need to be rotated, as one agent taken for a prolonged period may cause resistance to develop. In this way, the blastocystis will be less likely tot build up an immunity to any of the selected items.
Prognosis Blastocystis can remain in the intestines for weeks, months, or years. |
