摘要:
Disposable plates for performing microbial antibiotic susceptibility testing with multiple channels can be inoculated with a microorganism and antimicrobial agent. The antimicrobial agent may be presented as a gradient of concentrations in the plate. The susceptibility testing plates are configured to allow viewing of microbial growth, and/or to be received in an automated instrument which analyzes same.

A device and method allow for detecting the presence of microorganisms in clinical and non-clinical specimens. The device, a sensor, provides an environment to culture microbial organism colonies from a fluid sample, and a means to facilitate microbial detection and quantification, either manually or with an instrument. The sensor has a microorganism immobilization matrix layer and a sensor layer. Detected microbial colonies are immediately available for further testing. The sensor provides an area for accepting a fluid sample, a mechanism to immobilize the fluid sample on an interior surface of the plate, nutrients to facilitate growth of microorganisms in the sample, and a sensor for allowing the detection and/or enumeration of microorganism colonies within the sample.
摘要:
A method and apparatus for performing microbial antibiotic susceptibility testing include disposable, multi-chambered susceptibility plates and an automated plate handler and image acquisition and processing instrument. The susceptibility plates are inoculated with a microorganism (any suitable organism such as bacteria, fungi, protozoa, algae or viruses) and anti-microbial agent(s) are applied such that the microorganism is exposed to a variety of concentrations, or a gradient of each anti-microbial agent. The plates are then placed in the instrument, which monitors and measures the growth (or lack thereof) of the microorganisms. This data is used to determine the susceptibility of the microorganism to the antibiotics. Such a system automates antimicrobial susceptibility testing using solid media and Kirby-Bauer standardized result reporting. The system provides a level of automation previously associated only with broth microdilution testing, while retaining the advantages of the manual disk diffusion test.
摘要:
The present invention is directed to a method for separating, characterizing and/or identifying microorganisms in a test sample. The method of the invention comprises an optional lysis step for lysing non-microorganism cells that may be present in a test sample, followed by a subsequent separation step. The method may be useful for the separation, characterization and/or identification of microorganisms from complex samples such as blood-containing culture media. The invention further provides for the use of one or more identifier agents and interrogating the microorganism sample and/or said one or more identifier agents to produce measurements which characterizing and/or identifying the microorganism based on the produced measurements and/or the presence or absence of the identifier agent or a metabolized form of the identifier agent in the microorganism sample.

The present invention relates to methods and systems for scanning, detecting, and monitoring microorganisms on solid or semi-solid media using intrinsic fluorescence (IF) measurements. The methods are further directed to detection, characterization and/or identification of microorganisms on a solid or semi-solid media using intrinsic fluorescence (IF) measurements that are characteristic of said microorganisms.
摘要:
The present invention provides a method and system for monitoring, detecting, and/or characterizing a biological particle that may be present in a sample. The method may be accomplished in a sealed container by utilizing a first step time-dependent spectroscopic technique to obtain at least two measurements of a growth composition comprising a sample and correlating said measurements for the detection and/or characterization of a biological particle that may be present in the sample. The method further provides for a subsequent step for the separation, characterizion and/or identification of the microorganisms in the sealed container.
摘要:
The present invention is directed to a separation device or container that can be used in the separation, isolation or pelleting of microorganisms from a test samples known to contain or suspected of containing said microorganisms. Subsequently, the separated, isolated or pelleted microorganism sample can undergo one or more interrogation steps to provide measurements useful for the characterization and/or identification of microorganism. In one aspect of the present invention, the interrogation steps can occur in situ in the separation device or container described herein.

摘要:
A device and method allow for collection of a blood specimen and for detecting the presence of microorganisms in the blood specimen. The device, a sensor plate under vacuum, provides an environment to culture microbial organism colonies from a blood sample, and a means to facilitate microbial detection and quantification, either manually or with an instrument. The vacuum sensor plate has a microorganism immobilization matrix layer and a sensor layer. Detected microbial colonies are immediately available for further testing. A kit is provided having a needle assembly for direct draw of blood from a patient onto the immobilization layer within the vacuum sensor plate. The sensor plate provides an area for accepting a blood sample, a mechanism to immobilize the blood sample on an interior surface of the plate, nutrients to facilitate growth of microorganisms in the sample, and a sensor layer for allowing the detection and/or enumeration of microorganism colonies within the blood sample.
摘要:
This invention relates to a novel reagent and a method of using the reagent in an immunoassay to detect antigens, particularly antigens immunocomplexed with their corresponding or cross-reacting antibodies. In particular, this reagent and method increase the detection of human immunodeficiency virus HIV-1 p24 core antigen.
