Abstract:
The emergence of plasmid-mediated colistin resistance carried by mcr genes and polymyxin resistance in carbapenem-resistant bacteria poses a threat to antibiotic therapy of bacterial infections. The worldwide spread of colistin resistance carried by mcr genes, particularly in Enterobacteriaceae, points to the possibility of the spread of this type of resistance also in non-fermenting Gram-negative bacteria such as Pseudomonas aeruginosa or Acinetobacter baumannii. This study provides information on the first described occurrence of the mcr-4 gene in A. baumannii isolated from imported turkey liver obtained in the retail market of the Czech Republic.
