Table 2 Summary of cluster analysis with strains belonging to different E. coli pathogroups

From: Virulence gene profiling of enterohemorrhagic (EHEC) and enteropathogenic (EPEC) Escherichia coli strains: a basis for molecular risk assessment of typical and atypical EPEC strains

  Cluster 1 Cluster 2 Total
Pathogroup Strains (%) Serotypes (%) Strains (%) Serotypes (%) Strains Serotypes
EHEC 64 (100.0) 14 (100) 0 (0) 0 64 14
typical EPEC 46 (63.0) 9 (47.4) 27 (37.0) 12 (63.2) 73 19a
atypical EPEC 129 (54.9) 40 (50.0) 106 (45.1) 45 (56.25) 235 80b

all groups 239 63 206 95 445 151
  1. a) two serotypes grouped into Clusters 1 and 2
  2. b) 5 serotypes grouped each in Cluster 1 and Cluster 2.
  3. c) faecal isolates from healthy humans or animals which tested negative for eae, bfpA and stx-genes.
