Effectiveness of BOX-PCR in Differentiating Genetic Relatedness among Salmonella enterica Serotype 4,[5],12:i:- Isolates from Hospitalized Patients and Minced Pork Samples in Northern Thailand

Figure 2

Amplicon profile and phylogenetic tree from BOX-PCR (a), GTG₅-PCR (b), REP-PCR (c), and ERIC-PCR (d) of 28 Salmonella isolates collected in northern Thailand. PCRs were performed using the primer sets listed in Table 1. Phylogenetic trees were constructed using curve-based algorithm (Pearson correlation). The number at the branch node indicates percent amplicon profile similarity. Dark blue shade represents high cluster similarity. Light blue shade represents low cluster similarity. ID, Salmonella strains: en, from the minced pork sample; numeral, from feces of hospitalized patients.
