Developing an efficient multiplex PCR method to detect mcr-like genes

Dear Editor,Since 2016, a growing number of mobile colistin resistance(mcr) genes have been identified and characterized (Liu et al., 2016). In addition to mcr-1 and its variants, mcr-2 to mcr-8 have now been reported, which reflects a significant threat to public health and agricultural production (Sun et al.,2018).
