METHOD FOR RAPID DETERMINATION OF SENSITIVITY OR RESISTANCE TO POLYMYXINS IN BACTERIA OF PSEUDOMONADACEAE AND MORAXELLACEAE FAMILIES (NON-FERMENTATIVE GRAM NEGATIVE BACTERIA)

摘要

A method for the rapid determination of resistance or resistance to antibiotics of the polymyxin family, gram-negative non-fermentative bacteria of the Pseudomonadaceae and Moraxellaceae families, characterized in that it comprises: - an inoculum step of said bacteria in a liquid medium comprising at least: ▪ a yeast extract and polyethylene glycol sorbitan monooleate, and ▪ a colored pH indicator all constituting a liquid composition, then: - a step of contacting by any suitable means of said liquid composition with an antibiotic compound of the family of polymyxins, then - the incubation of the entire composition-liquid antibiotic compound, for a period of 2 to 4 hours, then the observation and evaluation during this same period or at the resulting from it, the color change of said set
