In the European Union, salmonellosis is one of the most important zoonoses reported. Poultry meat and egg products are the most common food matrices associated with presence. Moreover, wild and domestic animals could represent an important reservoir that could favour the direct and indirect transmission of pathogens to humans.

Using a combined Oxford Nanopore (ONT) long-reads and Illumina short-reads sequencing approach, an E.

A clone harbouring a conjugative plasmid of emerging . Infantis (pESI)-like megaplasmid, carrying multidrug resistant (MDR) and extended-spectrum beta-lactamases (ESBL) genes, has spread in the Italian broiler chicken industry also causing human illness.

In this study, we report the first evidence of -1-mediated colistin resistance in four multidrug resistant (MDR) out of 324 infantis from the Italian antimicrobial resistance (AMR) monitoring (2001-2017) in broilers and broiler meat. Two were also Extended Spectrum Beta-Lactamases (ESBL)-producing isolates.

Recently, it has been increasingly detected in Italian dairy cattle herds. The aim of this study was to analyse the differences between ST1 MRSA and methicillin-susceptible S.

Extended spectrum beta-lactamase (ESBL) and AmpC genes, plasmid-mediated quinolone resistance (PMQR) and co-resistances were investigated.
