Building the National Antimicrobial Resistance Surveillance Network in Animals in Greece: A "One Health" Approach.

It is widely accepted that, in order to prevent and control antimicrobial resistance (AMR), surveillance systems across human, animal and environmental sectors need to be integrated, in a One Health approach. Currently, in Europe, there are surveillance networks established only for the human and food sector and, until now, there has been no organized effort to monitor AMR in bacterial pathogens derived from diseased animals in Europe. Since 2017, efforts to fill this gap have taken place by the European Antimicrobial Resistance Surveillance network in a veterinary medicine (EARS-Vet) initiative, included in the EU Joint Action on AMR and Healthcare-Associated Infections (EU-JAMRAI).

KPC-2-producing Klebsiella pneumoniae infections in Greek hospitals are mainly due to a hyperepidemic clone.

To verify the presence of Klebsiella pneumoniae carbapenemase-producing (KPC-producing) Klebsiella pneumoniae in Greece, we asked 40 Greek hospitals participating in the Greek System for the Surveillance of Antimicrobial Resistance (GSSAR) to apply a combination of the modified Hodge test plus EDTA synergy test on all K. pneumoniae clinical isolates obtained from February 2008 which displayed reduced susceptibility to carbapenems (MIC of imipenem > or = 1 mg/L). The presence of the blaKPC gene was confirmed by PCR and sequencing.
