Dientamoeba fragilis is a pathogenic protozoan of the human gastrointestinal tract with a worldwide distribution. In developed countries, D. fragilis is emerging as a more prevalent cause of gastrointestinal disease than Giardia intestinalis Dientamoeba fragilis is a species of single-celled excavates found in the gastrointestinal tract of some humans, pigs and gorillas. It causes gastrointestinal upset in some people, but not in others. It is an important cause of travellers diarrhoea, chronic diarrhoea, fatigue and, in children, failure to thrive.Despite this, its role as a commensal, pathobiont, or pathogen is still debated
Dientamoeba fragilis belongs to the trichomonad group of protozoan parasites and it has been implicated as a cause of gastrointestinal disease with world-wide prevalences ranging from 0.5% to 16%. The majority of patients with dientamoebiasis present with gastrointestinal complaints . Under de senaste åren har PCR-baserade diagnostiska metoder etablerats för diagnostik av fecesprotozoer, huvudsakligen Giardia, Cryptosporidium och Entamoeba histolytica men även Dientamoeba fragilis, E.
Dientamoeba fragilis (D. fragilis) and Blastocystis hominis (B. hominis) are parasites which can infect the human digestive tract. People infected with these parasites can often be asymptomatic however, common gastrointestinal symptoms that may be reported can include diarrhoea or constipation, abdominal discomfort, bloating, gas and abdominal pain What is Dientamoeba fragilis?

What are the symptoms of infection with Dientamoeba fragilis? Many infected people do not have any symptoms. The most common symptoms are diarrhea and abdominal pain
Dientamoeba fragilis is an ameba of low pathogenicity that occasionally causes diarrhea in affected patients. 105, 106 A variety of other amebae are also, occasionally, associated with mild GI disease, including Entamoeba hartmanni, Entamoeba coli, Entamoeba polecki, Iodamoeba buetschlii, and Endolimax nana Infectious disease. Dientamoebiasis is a medical condition caused by infection with Dientamoeba fragilis, a single-cell parasite that infects the lower gastrointestinal tract of humans. It is an important cause of traveler's diarrhea, chronic abdominal pain, chronic fatigue, and failure to thrive in children Dientamoeba fragilis is a common enteropathogen of humans. Recently a cyst stage of the parasite was described in an animal model; however, no cyst stage has been described in detail from clinical samples. We describe both cyst and precystic forms from human clinical samples Dientamoeba fragilis is a single-celled protozoan, closely related to the trichomonads. Reported worldwide as causing human gastrointestinal symptoms, D. fragilis is very common and is second only to Blastocystis spp. Dientamoebiasis equals or exceeds the incidence of giardiasis Communicable Diseases Factsheet Dientamoeba fragilis is a parasite that is commonly found in the gastrointestinal tract of humans. It may cause illness in some people. The parasite is most likely transmitted via the faecal-oral route. Good hygiene practices should be used to help prevent infection Dientamoeba fragilis Last updated: 4 January 2016 What is Dientamoeba fragilis
Dientamoeba fragilis is a protozoan parasite emerging as a cause of diarrhoea and irritable-bowel-like gastrointestinal disease in humans with a propensity for establishing long-term, chronic infections in humans. [ncbi.nlm.nih.gov] Chronic infection occurs after 1-2 months of illness and is manifested by abdominal pain Dientamoeba fragilis is an important and underestimated cause of gastrointestinal disease in both the autochthonous and immigrant or traveller population. More studies are needed to clarify its optimal treatment and the role played by E. vermicularis in its transmission and maintenance

Dientamoeba fragilis is an enteric protozoan parasite that remains neglected, probably due to the misconception that it is uncommon and non-pathogenic. As more information became available and antimicrobial agents were developed with activity against this parasite, it became clear that D. fragilis is responsible of an active infection, associated with symptoms such as abdominal pain and diarrhea Dientamoeba fragilis is a nonflagellate trichomonad parasite and is one of the smaller parasites that can live in the human large intestine. Unlike most other intestinal protozoa, its life cycle has no cyst stage; thus, infection between humans occurs during the trophozoite stage Dientamoeba fragilis is an intestinal parasite that has attracted increasing interest due to its high prevalence and potential to perpetrate long-standing gastrointestinal symptoms.

Dientamoeba fragilis is a trichomonad parasite of the human intestine that is found worldwide. However, the biological cycle and transmission of this parasite have yet to be elucidated. Although its pathogenic capacity has been questioned, there is increasing evidence that clinical manifestations vary greatly Dientamoeba fragilis is an intestinal protozoan suspected of causing gastrointestinal symptoms, and its mode of transmission is unknown, although first described almost a century ago. A hypothesis is that Enterobius vermicularis is a vector for D. fragilis, and recently, D. fragilis DNA was detected within surface‐sterilized eggs of E. vermicularis
Dientamoeba fragilis (D. fragilis) is an intestinal parasite frequently detected in humans with abdominal pain and diarrhoea, but it is also commonly found in asymptomatic subjects.Hence its clinical relevance is often disputed.

Dientamoeba fragilis, a flagellate protozoan parasite that inhabits the human bowel, was first described 100 years ago by Jepps and Dobell, who thought of it as a non-pathogenic organism.1 Since then, many studies have assessed the pathogenicity of D. fragilis in two indirect ways. First, by linking its presence to gastrointestinal symptoms, including diarrhoea and abdominal pain. Dientamoeba fragilis is one of the most important diarrhea-causing protozoa and is distributed worldwide. Recent studies demonstrated the pathogenic potential and implicated it as a common cause of gastrointestinal disease
