A system and method with increased sensitivity to microorganism growth. The system includes signal processing electronic circuit connected to a consumable or vessel through two or more electrodes that fully penetrate the vessel and are in contact with the fluid contents. The electronic circuit is configured to detect a component of the total impedance of the sample, specifically the “out-of-phase” or imaginary reactance component, which has a sensitive response to organism growth in a frequency-dependent manner. The system detects changes in both the composition of charged molecules in the liquid matrix and the number of microorganisms based on monitoring the sample for change in this parameter. This results in a 5-70% reduction in time-to-detection (TTD). The system and method detect organisms in a plurality of vessel shapes, volumes, and matrix (or media) formats. The electrodes are fully immersed in a continuous body of liquid sample. The distance between electrodes may be adjusted or tuned to fit the needs of the vessel. The voltage inputs can also be adjusted to allow proper detection of the contents within the vessel.

Reactance and capacitance sensing platform for detecting microorganisms

A container for culturing a blood sample. The container has a reservoir that is no larger than about 40 ml in volume with culture media therein varying in amount by volume 0.5 ml to about 20 ml. The container is adapted to receive a blood sample drawn from a patient, wherein the blood volume is about 1 ml to about 20 ml. In some embodiments the ratio of blood volume to culture media volume is about 2:1 to about 1:2 and the volume of blood does not exceed about 10 ml. In some embodiments, the media is lytic media. A method for using the container to culture a blood sample is also contemplated. In such method, the container is inoculated with the blood sample. In certain embodiments, the volume of the blood sample does not exceed 10 mls.

Blood culture system with low media volume

An apparatus and associated methods of use for a controlled combination of reagents is disclosed. The apparatus includes a vessel, a vessel insert, and a cap element. The vesselhas a body portionfor receiving a biological sample. The vessel insertreceives at least one reagent therein. Preferably, the vessel insertis received in a portionof the vessel. The cap elementis attached to the vesselto secure the vessel insertin the vessel. During use, the vessel insertis adapted to release its contents when the biological sample is introduced into the body portionof the vesselupon application of an intermixing force to the vessel insert. A variety of intermixing forces may be applied, depending upon the embodiment of the present invention and its associated methods of use.

Blood culture bottles with mechanisms for controlled release of substances into culture media

A system and method for developing applications (Apps) for automated assessment and analysis of processed biological samples. Such samples are obtained, combined with nutrient media and incubated. The incubated samples are imaged and the image information is classified according to predetermined criteria. The classified image information is then evaluated according to Apps derived from classified historical image information in a data base. The classified historical image information is compared with the classified image information to provide guidance on further processing of the biological sample through Apps tailored to process provide sample process guidance tailored to the classifications assigned to the image information.

Application development environment for biological sample assessment processing

A device for collecting a biological sample from a semi-solid surface. The device has a shaft with a proximate end and a distal end and a tip integrated with the shaft at the proximate end. The tip has a surface adapted to collect microorganisms thereon or release microorganism from, or both, wherein the adapted surface comprises at least one feature of a recess or extension to increase surface area of the tip and collect microorganisms thereon. Examples of such features include microfeatures with dimensions of about 1000 &#x3bc;m or less. Other examples include a pipette tip.
