Abstract: Various methods, devices, and systems for determining the susceptibility of infectious agents to anti-infectives are disclosed herein. A method comprises introducing an inoculum solution comprising the infectious agent into a sample receiving space of a diagnostic device. The sample receiving space comprises a plurality of growth control wells devoid of the anti-infective and a plurality of active electrode wells comprising the anti-infective at differing concentrations. A water immiscible liquid can be introduced into the sample receiving space to seal the plurality of wells and the diagnostic device can be incubated for a period of time. The minimum inhibitory concentration (MIC) of the anti-infective on the infectious agent can be determined by monitoring and comparing one or more solution characteristics of the inoculum solution within the active electrode wells with the one or more solution characteristics of the inoculum solution with the growth control wells.

Abstract: Various devices, systems and methods of detecting a susceptibility of one or more infectious agents to one or more anti-infectives are described herein. In one embodiment, a method of detecting the susceptibility of the infectious agents to the anti-infectives involves introducing a sample comprising the infectious agents to a filter comprising a filter surface. The filter surface can be configured to capture the infectious agents in the sample. The method can also involve introducing a solution to the filter surface such that the solution is in fluid communication with the infectious agents captured on the filter surface. The solution can comprise nutrients and one or more anti-infectives. The method can further involve monitoring an oxidation reduction potential (ORP) of the solution using one or more parameter analyzers coupled to a sensor currently in fluid communication with the solution to assess the susceptibility of the infectious agents to the anti-infectives.

Abstract: Various apparatus, systems, and methods for measuring a solution characteristic of a sample comprising microorganisms are disclosed. In one embodiment, a sensor apparatus is disclosed comprising a sample container comprising a sample chamber configured to receive the sample and a reference sensor component comprising a reference conduit having a reference conduit cavity defined therein. The reference conduit cavity can be at least partially filled with a reference buffer gel, buffer solution, or wicking component. A segment of the reference conduit can extend into the sample chamber. A reference electrode material can be positioned at a proximal end of the wicking component or extend partially into the reference conduit cavity. The sensor apparatus can also comprise an active sensor component having an active electrode in fluid contact with the sample. The sample in the sample chamber can be aerated through an aeration port defined along a surface of the sample container.

Abstract: Various apparatus, systems, and methods for measuring a solution characteristic of a sample comprising microorganisms are disclosed. The measured solution characteristic can be used to generate a standardized inoculum. In one embodiment, a sensor apparatus is disclosed comprising a sample container having a chamber lateral wall surrounding a chamber cavity configured receive the sample, a reference sensor fabricated as a container cap and comprising a reference electrode material and, and an active sensor made of a substrate covered in part by an active electrode layer. The active sensor can be coupled to at least part of the chamber lateral wall at a window opening defined along the chamber lateral wall. The solution characteristic can be measured using a reader configured to electrically couple to the sensor apparatus and measure the solution characteristic based on a potential difference between the active sensor and the active sensor.
