AUTOMATED SYSTEM FOR THE LYSIS OF MICROORGANISMS PRESENT IN A SAMPLE, FOR EXTRACTION AND FOR PURIFICATION OF THE NUCLEIC ACIDS OF SAID MICROORGANISMS FOR PURPOSES OF ANALYSIS

摘要

A method for collecting microorganisms when contained in a fluid includes (i) introducing the fluid into a cavity of a collecting device via at least one admission duct, (ii) capturing the microorganisms when contained in the fluid with a set of beads retained in the cavity as the fluid passes through the set of beads, (iii) evacuating the fluid from the cavity via at least one evacuating duct, (iv) introducing a reaction liquid into the cavity via at least one admission channel, (v) collecting the microorganisms from the set of beads with the reaction liquid as the reaction liquid passes through the set of beads, and (vi) evacuating the reaction liquid from the cavity via at least one evacuating channel.
