Plasmid-mediated colistin resistance gene mcr-1 in Escherichia coli and Klebsiella pneumoniae isolated from market retail fruits in Guangzhou, China.

ABSTRACT:

Background

As a result of the growing prevalence of the plasmid-mediated mobile colistin resistance gene mcr-1 among Gram-negative bacteria, the surveillance of mcr-1 has been globally applied. In our study, we aimed to shed light on the possibility of transmission of mcr-1-resistant isolates through market retail fruits.

Methods and results

Herein, 133 different fruit surface samples were collected and screened for the different MCR variants (mcr-1 to mcr-8) using PCR and confirmed with sequencing. We identify for the first time mcr-1-carrying Escherichia coli and Klebsiella pneumoniae from market retail fruits in Guangzhou, China. Minimum inhibitory concentrations were detected by the broth microdilution method. Liqui
