Figure. Enterobacterial repetitive intragenic consensus (ERIC)–PCR ERIC2 primers. Lane 1, molecular mass ladder; lanes 2–7, nonoutbreak isolates; lanes 8–9, isolates from baby tea; lane 10, isolate from fennel; lanes 11–15, isolates from salmonellosis patients. ERIC PCR with ERIC2 primer (5′-AAGTAAGTGACTCGGGTGAGCG-3′) was used. DNA was isolated by using the InvitrogenPure Link Genomic DNA purification kit (Invitrogen, Carlsbad, CA, USA). Gene sequences were amplified in a Perkin/Elmer thermal cycler (model 9600; PerkinElmer, Waltham, MA, USA). A DNA ladder was created by using Gene Ruler 100-bp DNA Ladder Plus (Fermentas, Glen Burnie, MD, USA).
