Development of a reverse transcription-quantitative PCR system for detection and genotyping of aichi viruses in clinical and environmental samples.

ABSTRACT: Aichi viruses (AiVs) have been proposed as a causative agent of human gastroenteritis potentially transmitted by fecal-oral routes through contaminated food or water. In the present study, we developed a TaqMan minor groove binder (MGB)-based reverse transcription-quantitative PCR (RT-qPCR) system that is able to quantify AiVs and differentiate between genotypes A and B. This system consists of two assays, an AiV universal assay utilizing a universal primer pair and a universal probe and a duplex genotype-specific assay utilizing the same primer pair and two genotype-specific probes. The primers and probes were designed based on multiple alignments of the 21 available AiV genome sequences containing the capsid gene. Using a 10-fold dilution of plasmid DNA containing the target sequences, i
