Detection of Cryptosporidium oocysts in human fecal specimens by an indirect immunofluorescence assay with monoclonal antibodies.
An indirect fluorescence assay (IFA) with monoclonal antibodies developed for the detection of Cryptosporidium oocysts in fecal smears (Meridian Diagnostics, Inc., Cincinnati, Ohio) was compared with the Zeihl-Neelsen-modified acid-fast stain (MAFS) in 119 human fecal specimens collected between 1984 and 1987. The sensitivity of the IFA was 100%; all 56 specimens positive by MAFS exhibited fluo...
متن کاملDientamoeba fragilis DNA detection in Enterobius vermicularis eggs
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. Using real-time PCR, we detected D. fragilis ...
متن کاملIn vitro susceptibility testing of Dientamoeba fragilis.
Dientamoeba fragilis is a commonly encountered trichomonad which has been implicated as a cause of gastrointestinal disease in humans. Despite the frequency of reports recording infections with this parasite, little research has been undertaken in terms of antimicrobial susceptibility. The aim of this study was to evaluate the susceptibility of D. fragilis to several commonly used antiparasitic...
متن کاملAdvances on Dientamoeba fragilis Infections
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 be‐ came available and antimicrobial agents were developed with activity against this para‐ site, it became clear that D. fragilis is responsible of an active infection, associated with symptoms such as abdominal pain and dia...
متن کاملEvaluation of three diagnostic methods, including real-time PCR, for detection of Dientamoeba fragilis in stool specimens.
Dientamoeba fragilis is a protozoan parasite of humans that infects the mucosa of the large intestine and is associated with gastrointestinal disease. We developed a 5' nuclease (TaqMan)-based real-time PCR assay, targeting the small subunit rRNA gene, for the detection of D. fragilis in human stool specimens and compared its sensitivity and specificity to conventional PCR and microscopic exami...
