FIG 2.

Four clinical isolates analyzed by mPCR for Aeromonas species identifications. Each primer set was designed to be specific for the particular species and to have a unique amplicon size when analyzed by agarose gel electrophoresis. Also included in the mPCR was a primer set targeting 16S rRNA genes, which served as an internal PCR control (461 bp). Lane 1, 50-bp DNA marker; lane 2, A. caviae (70 bp); lane 3, A. media (99 bp); lane 4, A. hydrophila (144 bp); and lane 5, A. veronii (244 bp).
