Development and Preliminary Application of a Triplex Real-Time Quantitative PCR Assay for the Simultaneous Detection of Entamoeba histolytica, Giardia lamblia, and Cryptosporidium parvum.

ABSTRACT:

Background

The protozoan parasites including Entamoeba histolytica, Giardia lamblia, and Cryptosporidium parvum can infect the human intestinal tract and cause serious diseases. In this study, we aimed to develop a triplex real-time quantitative PCR (qPCR) for the simultaneous differential detection of these three intestinal protozoa.

Methods

Specific primers and TaqMan probes were designed for the 16S-like SSU rRNA sequence of E. histolytica, the gdh sequence of G. lamblia, and the 18srRNA sequence of C. parvum. A triplex qPCR assay was developed based on single-duplicate experiments to evaluate its limit of detection (LOD), specificity, stability, and reproducibility. Additionally, 163 fecal samples from patients with diarrhea who
