colonization of the mammalian gut and of the genitourinary tract. Here, we report the
analysis of a collection of 75 strains of human and animal origin by using serotyping,
multilocus sequence typing, whole genome DNA-array hybridizations and sequence
comparison of putatively virulence-associated loci. Although the most variable parts of the …
