METHOD FOR EXTRACTING DEOXYRIBONUCLEIC ACIDS (DNA) FROM MICROORGANISMS POSSIBLY PRESENT IN A BLOOD SAMPLE

摘要

The present invention relates to a method for extracting DNA from microorganisms possibly present in a blood sample, comprising the following steps: i) filtration of a blood sample through a filtration membrane, the pores of which have a diameter ranging from 0.01 µm to 50 µm, in particular from 0.1 µm to 10 µm, and most particularly from 0.2 µm to 1 µm; ii) washing of said filtration membrane; and iii) extraction of the deoxyribonucleic acids from the microorganisms possibly present on said filtration membrane.
