Fig. 2From: Genomic fingerprints of Escherichia coli strains isolated from surface water in Alborz province, IranCluster analysis by ERIC-PCR fingerprint of 100 E. coli isolates. The bottom bar indicates the isolates number, while the right bar indicates the percentage of similarity. Cluster analysis at a coefficient of 75% similarity (red line), grouped 100 isolates into 9 clusters, designated E1–E9. Each cluster has demonstrated a characteristic number of strains as well as separate inter- and intra-group similarity relationsBack to article page
