Genetic relatedness of the isolates was assessed using semi-automated rep-PCR on the DiversiLab® System (bioMérieux) after following the manufacturer’s guidelines. Data were analyzed and interpreted using internet-based DiversiLab software (v. 3.4) with the Kullback-Leibler correlation coefficient. Strains presenting a similarity of ≥95% were considered clonally related [13 (link)]. Multilocus sequence typing (MLST) was performed on A. baumannii isolates that were not susceptible to carbapenems following protocols previously described by Bartual et al. 2005 [21 (link)] and Diancourt et al. 2010 [22 (link)] available at the PubMLST website (http://pubmlst.org/acinetobacter, accessed on 30 December 2020).
