This study was conducted to explore the prevalence and transmission of mcr-1 Escherichia coli among healthy rural residents in Shandong, China, and to provide theoretical basis for the prevention and control of spread and treatment of multi-drug resistant Escherichia coli. A total of 218 healthy residents from 3 villages in Guan County, Shandong Province, China were included in this study, and their fecal samples were collected. Colistin-resistant Escherichia coli were selected, and their drug sensitivity and plasmids' transferability were measured. After analysis, some conclusions can be drawn. The colistin-resistant Escherichia coli, most strains of which are MDROs, is common and highly transmissible in healthy residents in rural areas in China. Interventions should be implemented to prevent the spread of colistin-resistant Escherichia coli through health education and tighter regulation of antibiotics.

Poor wear- and corrosion-resistance of 316L SS implants are critical problems in orthopedic implants. This study aims to improve the wear- and corrosion-resistance of 316L SS through surface coating. In this study, a bilayer composite coating consisting of polyether ether ketone (PEEK) as the first layer, and titania (TiO)- and Cu-doped mesoporous bioactive glass nanoparticles (Cu-MBGNs) were deposited as the second layer on a 316L SS electrophoretic deposition (EPD).
