GES-11-producing Acinetobacter baumannii clinical isolates from Tunisian hospitals: Long-term dissemination of GES-type carbapenemases in North Africa

•A. baumannii isolates producing GES-11 ESBL and OXA-23 carbapenemase from Tunisia as early as 2006.•We illustrate the emergence of plasmid-encoded GES-11 in A. baumannii in North Africa.•We illustrate the transferability of these plasmid-encoded GES-type β-lactamases in A. baumannii.•Carbapenem-resistant A. baumannii in North African hospitals is a matter of concern.
