Molecular Serogrouping of Shiga Toxin-Producing Escherichia coli Using Suspension Array.

Toro M, Najjar MB, Ju W, Brown E, Zhao S, Meng J

A suspension array assay was developed for molecular serotyping of the seven most prevalent Shiga toxin-producing Escherichia coli (STEC) serogroups (O26, O45, O103, O111, O121, O145, and O157). Fluorescence values of 59 STEC were 30 to >270 times greater than the signals of negative controls, demonstrating the method's effectiveness for the molecular serotyping of STEC.
