Journal ArticleDOI
Enteric protozoa in the developed world: a public health perspective.
TL;DR: This review discusses the common enteric protozoa from a public health perspective, highlighting their epidemiology, modes of transmission, prevention, and control, and suggests a multidisciplinary approach to their prevention and control.
Journal ArticleDOI
Clinical Significance of Enteric Protozoa in the Immunosuppressed Human Population
Damien Stark,Damien Stark,Joel Barratt,Joel Barratt,S. J. van Hal,Deborah Marriott,Deborah Marriott,J. Harkness,J. Harkness,John Ellis +9 more
TL;DR: The current state of knowledge on the significance of enteric parasitic protozoa as a cause of disease in immunosuppressed persons is summarized and guidance on recent advances in diagnosis and therapy for the control of these important parasites is provided.
Journal ArticleDOI
Evaluation of Multiplex Tandem Real-Time PCR for Detection of Cryptosporidium spp., Dientamoeba fragilis, Entamoeba histolytica, and Giardia intestinalis in Clinical Stool Samples
Damien Stark,Sarwat Al-Qassab,Joel Barratt,Joel Barratt,K. Stanley,Tamalee Roberts,Tamalee Roberts,Deborah Marriott,Deborah Marriott,J. Harkness,J. Harkness,John Ellis +11 more
TL;DR: The MT-PCR assay was able to provide rapid, sensitive, and specific simultaneous detection and identification of the four most important diarrhea-causing protozoan parasites that infect humans and highlights the lack of sensitivity demonstrated by microscopy.
Journal ArticleDOI
Comparison of microscopy, two xenic culture techniques, conventional and real-time PCR for the detection of Dientamoeba fragilis in clinical stool samples.
Damien Stark,Damien Stark,Joel Barratt,Joel Barratt,Tamalee Roberts,Tamalee Roberts,Deborah Marriott,Deborah Marriott,J. Harkness,J. Harkness,John Ellis +10 more
TL;DR: Results show that RT-PCR is the diagnostic method of choice for the detection of D. fragilis in clinical samples and, as such, should be considered as the gold standard for diagnosis.
Journal ArticleDOI
Description of Dientamoeba fragilis cyst and precystic forms from human samples.
Damien Stark,L. S. Garcia,Joel Barratt,Owen Phillips,Tamalee Roberts,Deborah Marriott,J. Harkness,John Ellis +7 more
TL;DR: In this paper, the authors described both cyst and precystic forms from human clinical samples of the Dientamoeba fragilis from a human clinical sample and showed that the precyst stage of the parasite can be identified in detail from clinical samples.
