Gel electrophoresis of the cluster 1 specific PCR products (inverted image). PCR products (3 μl) were separated on 1.4% agarose gels. Isolates belonging to the major outbreak strain (cluster 1) are highlighted in green. (A) Clinical isolates from the neurorehabilitation clinic that were used to setup the PCR. (B) Further clinical isolates that occurred from June 2015 till April 2016 in the neurorehabilitation clinic, and were PCR-typed prior WGS. (C) Ten epidemiologically independent ESBL-producing (A–J) and carbapenemase-producing (K–T) K. pneumoniae isolates, respectively (see Table S3), used to check the specificity of the PCR. Interpretation: all three bands present: isolate belongs to cluster 1 (“outbreak strain”); all bands present but PCR product of 4,160 kb missing: isolate probably belongs to cluster 1; no PCR product or only amplification of the hem product: isolate does not belong to cluster 1.
