Between 2021 and 2024, we detected carbapenemase gene blaOXA-181 in 16 of 11,398 Salmonella enterica (SE) isolates: 10 SE 1,4,[5],12:i:-, three Bovismorbificans, two London and one Rissen from pigs, humans, pork meat and wild roe deer. The gene was first detected in pig isolates, later in humans, suggesting zoonotic transmission. Phylogenetic analysis indicated that horizontal transfer, mainly through plasmids, contributed to the spread. These findings highlight a possible emerging public health threat and the importance of One Health surveillance.

Abstract
Between 2021 and 2024, we detected carbapenemase gene blaOXA-181 in 16 of 11,398 Salmonella enterica (SE) isolates: 10 SE 1,4,[5],12:i:-, three Bovismorbificans, two London and one Rissen from pigs, humans, pork meat and wild roe deer. The gene was first detected in pig isolates, later in humans, suggesting zoonotic transmission. Phylogenetic analysis indicated that horizontal transfer, mainly through plasmids, contributed to the spread. These findings highlight a possible emerging public health threat and the importance of One Health surveillance.| File | Dimensione | Formato | |
