  • a All populations except Swedish pyelonephritis cohort included compromised hosts.

  • b Sums of “any III” plus “any II” are greater than total number of papG-positive strains, since strains with both alleles II and III are counted both as any III and any II. (Adapted, with permission, from reference7.)

  • c Present study.

  • d Alleles were determined by PCR assay. Data are from reference 7.

  • e Alleles were determined by DNA probe hybridization. Data are from reference 26.
