Genotype Cluster Analysis in Pathogenic Escherichia coli Isolates Producing Different CDT Types

Table 4

Different cdt-type strains and related genotype based on other virulent genes and profile designation based on cooccurrence of plasmid-borne genes. espP: profile A, etpD: profile B, katP: profile C, espP/katP: profileD, espP/sfpA: profile E, etpD/katP: profile F, etpD/sfpA: profile G, katP/sfpA: profile H, etpD/katP/sfpA: profile I, espP/etpD/katP: profile K, espP/etpD/katP/sfpA: profile L, and profile M: Indicates the absence of plasmid genes and presence of chromosomal genes (fimH, fliC, hly, stx1, or stx2).
