Dientamoeba fragilis
Dientamoeba fragilis
Dientamoeba fragilis (/daɪˌɛntəˈmiːbə ˈfrædʒɪlɪs/) is a species of protozoa that is commonly considered a parasite in the human gastrointestinal tract. The etymology of the term originates from the Greek words "dientamoeba" meaning "amoeba of the intestine" and "fragilis" meaning "fragile".
Description
Dientamoeba fragilis is a single-celled organism that is often associated with gastrointestinal upset, such as diarrhea, abdominal pain, and flatulence. However, many individuals who are infected with D. fragilis do not exhibit any symptoms. The organism is typically transmitted through the fecal-oral route, often due to poor hygiene or the ingestion of contaminated food or water.
Diagnosis
Diagnosis of a Dientamoeba fragilis infection is typically made through the examination of stool samples under a microscope. However, because the organism is fragile and does not survive well outside of the body, it can be difficult to detect in stool samples. Therefore, multiple samples may be needed to confirm a diagnosis.
Treatment
Treatment for Dientamoeba fragilis typically involves the use of antibiotics, such as metronidazole or paromomycin. However, because some individuals do not exhibit symptoms, treatment may not be necessary unless symptoms are severe or persistent.
