[The importance of being Dientamoeba fragilis]

Abstract

In recent years, interest in Dientamoeba fragilis on the part of biologists, clinicians and parasitologists has increased considerably due to the need to clarify the many unresolved issues related to the parasite and the associated infection. This paper aims to provide a summary of the state of knowledge of D. fragilis in its different aspects, and, through the analysis of the literature and the most recent data, the present review aims to record the reasons why this protozoan, although little known, should not be underestimated in the diagnosis of human parasitic infections also in Italy.
