polymyxin

Objective. To evaluate the possibility of using the colistin disk chelator application (CDCA) method as simple and available screening tool for detection of mcr-1-mediated resistance to polymyxins in Enterobacterales. Materials and Methods. A total of 47 colistin-resistant Enterobacterales isolates obtained in 2014–2020 within multicenter MARATHON study were included in the experiment. Colistin susceptibility testing was performed using Mueller–Hinton broth microdilution method according to ISO 20776-1:2006. Interpretation of the results was performed according to EUCAST v.

Spread of multiresistant bacteria makes us to reconsider our attitude to some well-known old antimicrobials, including polymyxins – a class of polypeptide antibiotics that are active against many multiresistant gram-negative nosocomial pathogens – …
