  1. 1)The ECOR subgroups are as defined previously [16].
  2. UTI, urinary tract infection. NBM, newborn meningitis.
  3. 2)+denotes that an intact clyA locus is present; Δ denotes that some deletion(s) had ocurred.
  4. 3)I-IV denotes the different deletion variants within the clyA locus as described in the text and in Figure1.
