FIG. 1.
(A) Structure of the blaVIM-1-carrying integron In-Ab10a. The direction of transcription is indicated by the arrows. The dotted rectangle to the left of the duplicated 3′ end of blaVIM-1 (Pseudo 59-be) represents the inverse core sequence of the cassette and the pseudo-core sequence located within the structural gene. The white-dotted rectangle on the right (VIM-1 59-be) represents 59-be of the blaVIM-1 cassette. (B to B”) PFGE of I-CeuI-digested genomic DNA of eight A. baumannii clinical isolates from the same setting. (B) TZ28 and TZ29/20 in the first two lanes represent carbapenem-resistant blaVIM-1-negative isolates used for control purposes. Genomic fragments of the six blaVIM-1-positive isolates are shown in the remaining lanes. Hybridizations with probes specific for 16S rRNA and blaVIM-1 genes are shown in panels B' and B”, respectively.
