Several other compounds have also been evaluated for the treatment either alone or in combination with the first or second line drugs.

Genomic studies provide evidence for all three routes, though experimental studies have yet to provide conclusive proof for the existence of either. Food and water precautions.

Conclusively stating that Blastocystis has an animal reservoir depends upon unraveling the true hominos of its transmission. Metabolic granules play a role in chemical processes that are necessary for the maintenance of life in the organism.

Fecal-oral transmission is the most accepted pathway, and recent studies have shown that transmission involves only the cyst form of the parasite. Tratamienot from top left: Whether all of these forms exist in the host intestine is unclear.

Molecular and Biochemical Parasitology. These hypotheses were made based on microscopy alone, which may be deemed misleading, hence more need to be done before making a definite conclusion.

Transition from vacuolar to amoeboid form reflects the progression from an asymptomatic to symptomatic state. To date a number of antimicrobial agents have been used to treat Blastocystis infection. Therefore, therapy should be limited to patients with persistent symptoms subsequent to a complete work up for alternative etiologies.

Kelesidis T, Pothoulakis C. Emerging impact on global health and development. A detailed ultra-structural study of amoeboid forms was published in Recently, the finding of different subsets of Blastocystis exhibiting resistance to metronidazole and associated with variable degrees of symptoms has underscored the importance of typing the subsets of the parasite tratamientoo order to foretell the clinical response and the need to treat.
