Bacterial typing of K. pneumoniae clinical isolates. A) PFGE of representative samples belonging to different STs as measured by MLST. Samples were arbitrarily described by capital letters which designate their PFGE profile. Each sample was run in duplicate. The asterisk indicates the region where profile A differs from profile C. A, B, C and D PFGE profiles corresponded to ST147, ST258, ST527 and ST37, respectively. B) Gel electrophoresis of ERIC-PCR of representative clinical isolates. Samples were arbitrarily described by lowercase letters which designate their ERIC profile. ERIC profiles a, b and c corresponded to ST147, ST258 and ST527 (see also Table 1).
