Absztrakt
Escherichia coli is a widely distributed bacterium and it takes part in the establishment of
the normal intestinal flora. Nonetheless, several E. coli strains are pathogenic and cause
illnesses. Its wide distribution and its genom’s plasticity give chance harbouring several
virulence and antibiotic genes. These genes can be spread between cohabiting bacterial
species with horizontal gene transfer.
Plasmid encoded colistin (mcr-1) resistance gene is belong to this group. Colistin or
polimixin E is a cationic polypeptid antibiotic. Hospitals reserve colistin as a last resort
antibiotic against multiresistant bacteria.
