Figure 2.

Two percent agarose gel electrophoresis showing the product of amplification of the 798-bp fragment of the 16S rRNA gene. DNA sequencing of such a fragment further allowed the identification of Nocardia farcinica. Lane 1 = PCR product obtained from a phlegmon sample of our patient; lane 2 = negative control (water); lane 3 = positive control (Streptococcus pneumoniae ATCC 49619); M = DNA size reference marker (50-2000-bp Amplisize, Biorad).
