The genomic epidemiology of mcr-positive Salmonella enterica in clinical patients from 2014 to 2017 in Sichuan, China and global epidemiological features

We read with interest the Wang et al. article in this journal describing the prevalence of mcr genes in 33, 205 Salmonella enterica isolated from England between 2014 and 2017.1 This work highlights that S. enterica is an important carrier for mcr genes and majority of S. enterica were isolated from human-associated samples.1 Recently, an international outbreak of multidrug-resistant (MDR) monophasic S. Typhimurium associated with chocolate products further indicated that S. enterica represent a serious public health hazard.
