Simultaneous detection of virulence factors from a colony in diarrheagenic Escherichia coli by a multiplex PCR assay with Alexa Fluor-labeled primers.

We have developed simultaneous detection of eight genes associated with the five categories of diarrheagenic Escherichia coli by the multiplex PCR assay with Alexa Fluor-labeled primers. This assay can easily distinguish eight genes based on the size and color of amplified products without gel staining.
