Title:
MICROORGANISM−COLLECTING CHIP, MICROORGANISM−COLLECTING KIT, METHOD OF QUANTIFYING MICROORGANISMS, SPECIMEN FOR CONFIRMING NORMAL STATE OF MICROORGANISM−QUANTIFYING APPARATUS AND MICROORGANISM−QUANTIFYING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2003/012397
Kind Code:
A1
Abstract:
It is intended to efficiently collect microorganisms from a test sample and accurately detect and quantify the thus collected microorganisms. A microorganism−collecting chip fundamentally comprising a filter for removing contaminants and another filter for capturing microorganisms. A microorganism−collecting kit comprising the above−described microorganism−collecting chip and a suction filtration means. The suction filtration means is exemplified by a negative pressure tube provided with a rubber stopper at the opening. The microorganism−collecting chip has a liquid specimen container into which a liquid specimen is to be injected and a hollow needle capable of penetrating through the rubber stopper provided at the opening of the negative pressure tube. A liquid specimen injected into the container is filtered under suction due to the pressure of the negative pressure tube. Contaminants are removed by using the contaminant−removing filter, while microorganisms are captured on the microorganism−collecting filter. Next, the microorganisms captured on the microorganism−collecting filter are detected and quantified by using the unit involving the microorganism−collecting filter.
