摘要:
A detection instrument determines whether a specimen container (e.g., blood culture bottle) is positive for presence of microbial agent growth therein. When the container is deemed positive it is made available (e.g, transferred or exposed to) to an automated instrument performing identification and/or characterization of the microbial agent. The identification and/or characterization instrument removes a portion of the sample from the specimen container and places it into a disposable separation and concentration device. The microbial agent is concentrated via optional selective lysis of non-microbial agent cellular material which may be present and centrifugation. A reading module reads the concentrated microbial agent using spectroscopic methods, e.g., measurements of intrinsic fluorescence. Such interrogation may occur while the microbial agent remains concentrated in the disposable device.

An automated instrument for identification and/or characterization of a microbial agent present in a sample. The instrument includes (a) a sample removal apparatus operative to remove a test sample from a specimen container and add the test sample to a disposable separation device; (b) a separation and concentration apparatus operative on the separation device to separate the microbial agent from other components which may be present in the test sample and concentrate the microbial agent within the separation device; and (c) a identification and/or characterization module interrogating the concentrated microbial agent to identify and/or characterize the microbial agent.

摘要:
A sampling device for a specimen container having a closure sealing the interior of the specimen container from the environment includes a needle, a body coupled to the needle and defining a chamber in fluid communication with the needle, the body further comprising a port forming an opening in the body, the port in fluid communication with the chamber. A multitude of the sampling devices may be stored in a cassette. The sampling devices may include a second chamber for separation and concentration of a microbial agent present in a sample. In this configuration second chamber is connected to the first chamber via a valve or the like.
摘要:
A method of testing a specimen sample contained within a sealed specimen container. A test sample is removed from the specimen container with a disposable sampling device. Non-microbial agent components of the test sample are lysed, thereby producing a lysed sample. The lysed sample is delivered to a disposable separation device. A microbial agent present in test sample is concentrated within the disposable separation device. The concentrated microbial agent is interrogated, e.g., spectroscopically.
摘要:
The present invention provides a method for detecting, and characterizing a microorganism present in a blood culture medium whereby the method may be accomplished utilizing a time-dependent spectroscopic technique to obtain at least two measurements directly of a blood culture medium and correlating said measurements for the detection and characterization of a microorganism, that may be present in the blood culture.
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 whereby the method may be accomplished non-invasively by utilizing a 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.
摘要:
The present invention is directed to methods and kits for separating, accumulating, characterizing and/or identifying microorganisms known to be present or that may be present in a test sample. The method of the invention comprises optional lysing non-microorganism cells and/or particulates that may be present in a test sample, followed by a subsequent filtration step for isolation and/or accumulation of microorganisms. The kit of the present invention may comprise at least one filter membrane or an integrated filtration and sample transfer device for isolation and/or accumulation of microorganisms.
