Title (EN) DEVICES, SYSTEMS AND METHODS FOR DETECTING VIABLE MICROORGANISMS IN A FLUID SAMPLE
(FR) DISPOSITIFS, SYSTÈMES ET PROCÉDÉS DE DÉTECTION DE MICRO-ORGANISMES VIABLES DANS UN ÉCHANTILLON DE FLUIDE
Abstract:
(EN) Various devices, systems and methods for detecting a susceptibility of a microorganism to an anti-infective are described herein. A method comprises introducing a sample comprising the microorganism to a first surface and a second surface; exposing the first surface comprising the microorganism to a first solution; exposing the second surface comprising the microorganism to a second solution, wherein the second solution comprises an anti-infective; separating the first solution from the first surface after exposing the first surface to the first solution; separating the second solution from the second surface after exposing the second surface to the second solution; monitoring a first electrical characteristic of a sensor upon introducing the first solution to the sensor; monitoring a second electrical characteristic of the sensor after introducing the second solution to the sensor; and comparing the first electrical characteristic and the second electrical characteristic to assess the susceptibility of the microorganism.
(FR) L'invention concerne divers dispositifs, systèmes et procédés de détection d'une sensibilité d'un micro-organisme à un anti-infectieux. Un procédé comprend les étapes suivantes : introduction d'un échantillon contenant le micro-organisme dans une première surface et une seconde surface ; exposition de la première surface contenant le micro-organisme à une première solution ; exposition de la seconde surface contenant le micro-organisme à une seconde solution, la seconde solution contenant un anti-infectieux ; séparation de la première solution et de la première surface après l'exposition de la première surface à la première solution ; séparation de la seconde solution et de la seconde surface après l'exposition de la seconde surface à la seconde solution ; surveillance d'une première caractéristique électrique d'un capteur lors de l'a présentation de la première solution au capteur ; surveillance d'une seconde caractéristique électrique du capteur après la présentation de la seconde solution au capteur ; et comparaison de la première caractéristique et de la seconde caractéristique électrique pour évaluer la sensibilité du micro-organisme.
