Abstract: The subject matter of the present disclosure generally relates to techniques for isolating bacterial cells from a biological sample comprising red blood cells. Using an aggregating agent and an anticoagulant during sedimentation permits separation of bacterial pathogens in the sample from red blood cells. The separated sedimentation layer, which is enriched in any bacterial pathogens, can be centrifuged and resuspended to concentrate the bacteria for additional analysis, such as bacterial identification and/or antibiotic susceptibility tests.

Abstract: The present disclosure relates to a consumable sample partition device and it assembly and use. The sample partition device can be used to test a sample for absence of microorganisms (sterility) and/or for concentration of said organisms (bio-burden). The sample partition device partitions the sample input volume into multiple discrete measurement zones with little or no loss of sample (e.g., zero-loss) and with little operator involvement, thereby reducing operator- and environment-based false positives.

Abstract: A device and/or methodology are described that include a mechanism for separating erythrocytes from other constituents of blood and for purifying leukocytes from blood. The separation and purification aspects may be provided in separate components or within the same component. The separation aspect assists in separating erythrocytes (red blood cells) from other cells in blood, such as by aggregation of the red blood cells. A suitable aggregation device or device component uses chambers with at least one small dimension (e.g., a microfluidic chip) to control the interaction of the blood with a solution containing a high molecular weight polymer (e.g., dextran) to achieve separation.

Abstract: The present disclosure relates to approaches for assessing a sample or the presence of microorganisms. The sample, in certain implementations may be assessed for one or both of absence of microorganisms (sterility) and/or for concentration of said organisms (bio-burden). sample partition device may be employed that partitions the sample input volume into multiple discrete measurement zones with little or no loss of sample (e.g., zero-loss) and with little operator involvement, thereby reducing operator- and environment-based false positives.

Abstract: Approaches are disclosed for calibrating a plurality of imaging devices, such as microscopes. In certain implementations, a calibration plate is employed that includes a variety of calibration features. The calibration features comprise a geometric calibration, an illumination calibration, and an optical calibration. Imaging devices calibrated in accordance with the present approaches may be used to generate images having consistent attributes, such as brightness, regardless of which imaging device is employed.

Abstract: A system includes a bacteria culture array that includes a plurality of chambers each configured to receive a portion of a sample that includes bacteria. Each individual chamber of the plurality of chambers includes a chamber opening configured to permit access of the portion of the sample to the individual chamber. The system also includes one or more sensors configured to collect data from the individual chamber. The sensors are configured to contact the sample. Additionally, the system includes a monitoring and analysis system that includes a processor configured to receive the data from the one or more sensors at a first time and a second time, compare the data received at the second time to the data received at the first time, and identify a portion of the plurality of chambers of the bacteria culture array based on the comparing.
