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 3

Clustering of Salmonella isolates collected from minced pork samples and feces of hospitalized patients in northern Thailand. Clustering of Salmonella isolates was performed using UPGMA algorithm at the indicated percent similarity of phylogeny obtained from Figure 2. The number of isolates in a cluster is indicated in color box. MH (yellow), S. 4,[5],12:i:- isolates from patients; MM (yellow), S. 4,[5],12:i:- isolates from minced pork; OB (gray), other Salmonella Serogroup B isolates from minced pork; TM (green), S. Typhimurium isolates from minced pork.
