Occurrence and characteristics of Escherichia coli mcr-1-like in rabbits in Shandong, China.

ABSTRACT: Polymyxin is regarded as the last retort to fight against multidrug-resistant (MDR) Enterobacteriaceae. The emergency and spread of polymyxin-associated resistance gene mcr-1 evoked great panic of no medicine to cure the bacterial infection in society. mcr-1 is widespread in domestic and wild animals. Therefore, continuous monitoring of its prevalence and characteristics is required. In this study, we used a polymerase chain reaction (PCR)-based method to detect the mcr-1 of Escherichia coli isolated from rabbits of Tai'an, China, and determined the characteristics of mcr-1-bearing plasmids. A total of 55 non-duplicated E. coli was recovered from the swabs of rabbit faeces. Plasmid profiling, plasmid and chromosome PCR, complete genome sequencing, a conjugation experiment, lactose fermenta
