“…Nonetheless, D. fragilis was not detected in these other species (176). In support of the findings reported by Stark et al (176) Crotti et al (161) were the first to identify D. fragilis in the stools of farmed pigs using Giemsa-stained fecal smears. The role of pigs as a natural host of D. fragilis was further substantiated in a later study by Caccio et al (38), who used PCR and microscopy to confirm the presence of D. fragilis in farmed pigs.…”

SUMMARYDientamoeba fragilisis a protozoan parasite of the human bowel, commonly reported throughout the world in association with gastrointestinal symptoms. Despite its initial discovery over 100 years ago, arguably, we know less about this peculiar organism than any other pathogenic or potentially pathogenic protozoan that infects humans. The details of its life cycle and mode of transmission are not completely known, and its potential as a human pathogen is debated within the scientific community. Recently, several major advances have been made with respect to this organism's life cycle and molecular biology. While many questions remain unanswered, these and other recent advances have given rise to some intriguing new leads, which will pave the way for future research. This review encompasses a large body of knowledge generated on various aspects ofD. fragilisover the last century, together with an update on the most recent developments. This includes an update on the latest diagnostic techniques and treatments, the clinical aspects of dientamoebiasis, the development of an animal model, the description of aD. fragiliscyst stage, and the sequencing of the firstD. fragilistranscriptome.

“…Also pertinent to this debate is the fact that D. fragilis is capable of infecting pigs, having been detected in a population of farmed swine (38,161). Humans are the only known host of E. vermicularis.…”

“…However, it should be noted that D. fragilis has also been reported from a small number of animal hosts, including macaques, gorillas, swine, and a sheep. 5,[25][26][27] Attempts to induce experimental infections in a range of animals have not been successful. 5 In contrast, Giardia and Cryptosporidium are common in animals around the Sydney area.…”

Abstract. Dientamoeba fragilis is a commonly occurring pathogenic protozoan often detected at higher rates in stool samples than Giardia intestinalis. However, little is known about its life cycle and mode of transmission. A total of 210 environmental and household samples were examined for the presence of D. fragilis by culture and polymerase chain reaction. Of 100 environmental samples, D. fragilis was detected only in untreated sewage. In the household samples D. fragilis was detected in 30% of household contacts tested and was not detected in any domestic pets. This study provides evidence that environmental transmission of D. fragilis is unlikely and that pets played no role in transmission of the disease in this study. Direct transmission from infected persons is the most likely mode of transmission for D. fragilis. The study also highlights the need for household contacts to be screened, given the propensity of close contacts to become infected with the organism.
