Agarose gel electrophoresis results for the multiplex PCR assay with representative isolates of Listeria species. Lanes 1 to 6, L. monocytogenes reference isolates of ECI (F2365), ECII (H7858), ECIII (F6854), 4b but non-EC (J1-129), 1/2a but non-ECIII (F2-663), and non-4b and -1/2a (R2-503), respectively; lane 7, Listeria ivanovii (C2-011); lane 8, Bacillus cereus; lanes M1 and M2, Bio-Rad molecular weight markers (Bio-Rad, Hercules, CA). Genetic markers corresponding to the amplified fragments are indicated on the right. Molecular sizes are given (in base pairs) at the left. Isolates were obtained from the CDC and Cornell University, and original isolate identification numbers are used.
