Abstract
We report cases of two unrelated families who both presented with recurrent Dienta-moeba fragilis infections. Subsequent antimicrobial therapy resulted in the clearance of D. fragilis and total resolution of gastrointestinal symptoms in both families. This report highlights the potentially recurrent nature of D. fragilis infections and the need for laboratories to routinely test for this organism.
Highlights
Parasitology testing was performed on faecal samples fixed in Sodium acetate acetic acid formalin and permanently stained using a modified iron-haematoxylin stain as previously described.[4]
Several months after the initial presentation and subsequent successful treatment of the D. fragilis infection the Contribution: DS, main author, molecular analysis, microbiological and laboratory testing; JB, molecular analysis, microbiological and laboratory testing testing article input, proof reading; JE, molecular analysis, article input, proof reading; JH, clinical input, patient follow up article input, proof reading; DM, clinical input and treatment of patients, article input, proof reading

Summary
Parasitology testing was performed on faecal samples fixed in Sodium acetate acetic acid formalin and permanently stained using a modified iron-haematoxylin stain as previously described.[4]. The patients symptoms resolved after treatment and subsequent stool samples submitted post treatment (n=2) were negative for Dientamoeba by both microscopy and PCR.
