Figure 3From: Identification and detection of three new F17 fimbrial variants in Escherichia coli strains isolated from cattleMap of the f17A gene carried on plasmid pVir68. This gene corresponds to a mixture of f17Ac and f17Ad genes. The highly conserved region identified is shared by the both variants genes f17Ac and f17Ad and constitutes a likely recombination region. This region is located between the two matching regions of the forward specific primers for f17Ac and f17Ad.Back to article page
