Emergence of a Salmonella enterica serovar Typhimurium ST34 isolate, CFSA629, carrying a novel mcr-1.19 variant cultured from egg in China.

We report on an MDR S. Typhimurium ST34 CFSA629 isolate cultured from egg in China, harbouring an mcr-1.19 variant mapped to an IncHI2 plasmid. This highlights the importance of surveillance to mitigate dissemination of mcr-encoding genes among foodborne Salmonella. Improved surveillance is important for tackling the dissemination of mcr genes among foodborne Salmonella around the world.
