20100120085Method for separation, characterization and/or identification of microorganisms using mass spectrometry - 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 interrogation of the separated microorganism sample by mass spectrometry to produce a mass spectrum of the microorganism and characterizing and/or identifying the microorganism in the sample using the mass spectrum obtained.05-13-2010
20100120133Separation device for use in the separation, characterization and/or identification of microorganisms - 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.05-13-2010
20100124763Method for detection, characterization and/or identification of microorganisms in a sealed container - 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.05-20-2010
20100129814Method for separation and characterization of microorganisms using identifier agents - 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.05-27-2010
20100129857Methods for the isolation and identification of microorganisms - 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 methods for separating, characterizing and/or identifying microorganisms in situ within a single system.05-27-2010
