Multidrug-resistant Salmonella enterica serovar Virchow encoding bla CTX-M3 located on an IncN plasmid isolated from Turkish food of avian origin
blaCTX-M3 genes located in big plasmids (>300 kb) are wide spread among human isolatesin Mediterranean Regions. In the present study, the gene, located on a smaller plasmid,could be associated to food products of avian origin. To our knowledge, the presence ofthis gene in food isolates is very rare. This was the first time that blaCTX-M3 gene was foundin Salmonella in Turkiye.Although ESBLs were not frequent among the food isolates analysed (just one isolate from76 was positive), the presence of ESBLs in multiresistant strains including fluoroquinoloneresistance is worrying and should be prevented by prudent use of extended spectrum ßlactams.
