| Summary: | The objective of this review is to collect and present the results of relevant studies on an international level, on the subject of colistin resistance due to <i>mcr</i> genes prevalence in livestock animals. After a literature search, and using PRISMA guidelines principles, a total of 40 swine, 16 bovine and 31 poultry studies were collected concerning <i>mcr</i>-1 gene; five swine, three bovine and three poultry studies referred to <i>mcr</i>-2 gene; eight swine, one bovine, two poultry studies were about <i>mcr</i>-3 gene; six swine, one bovine and one poultry manuscript studied <i>mcr</i>-4 gene; five swine manuscripts studied <i>mcr</i>-5 gene; one swine manuscript was about <i>mcr</i>-6, <i>mcr</i>-7, <i>mcr</i>-8, <i>mcr</i>-9 genes and one poultry study about <i>mcr</i>-10 gene was found. Information about colistin resistance in bacteria derived from animals and animal product foods is still considered limited and that should be continually enhanced; most of the information about clinical isolates are relative to enteropathogens <i>Escherichia coli</i> and <i>Salmonella</i> spp. This review demonstrates the widespread dispersion of <i>mcr</i> genes to livestock animals, indicating the need to further increase measures to control this important threat for public health issue. |
