Addaptation of Rapid ResaPolymyxin Acinetobacter/Pseudomonas NP® as a feasible and rapid test to detect polymyxin B resistance

Abstract

Considering the need of rapidly determine polymyxin B susceptibility in carbapenem-resistant isolates, Rapid ResaPolymyxin Acinetobacter/Pseudonomas NP test was developed. In this study, we adapted the methodology for a reproducible in-house version, which presented excellent results for Acinetobacter baumannii. However, more adaptations for Pseudomonas aeruginosa became clearly necessary.
