In a specific study, stainless steel was inoculated with 10 7 CFU/cm 2 E. coli and K. pneumoniae, containing bla CTX-M-15 and bla NDM-1 (antibiotic-resistant genes) respectively. Thirty days later (at room temperature, 22˚ C), 10 4 viable cells remained; and, after 100 days, 100 CFU/cm 2 of E. coli remained. [63]

As of April 2021, ten mobilized colistin resistance genes termed mcr-1 through mcr-10 have been identified. They are homologous to each other, and work in similar ways. [24] The mcr-2 gene is a rare variant of mcr-1 and is found only in Belgium. The less-related mcr-3, mcr-4, and mcr-5 were identified in E. coli and Salmonella. [25]
