Figure 1 Agarose electrophoresis of PCR-RFLP 16S–23S spacers of different pyelonephritogenic E. coli strains, digested with RsaI (up) and TaqI (down). Strains numbered 1, 5 and 9 belong to the α1 subgroup (see text), strains 4, 6, 7 and 8 to α2, and strains 2 and 3 to β2 (1–9). M =1-kb ladder (Gibco BRL) molecular marker (75–10180 bp).
