PROCESS FOR CONCENTRATING AND PROCESSING FLUID SAMPLES

摘要

A method of treating a liquid sample having microbiological target species therein to concentrate the species and collect lysate is disclosed. The liquid sample comprises non-target microbiological particles, inorganic particles, and microbiological target species. The liquid is passed through a prefilter medium to allow the target species to pass through as filtrate and retain non-target microbiological products and inorganic particles thereon. The filtrate is contacted with a main filtration medium adapted to retain the target species thereon as retentate. The retentate is lysed to form a lysate containing target material that was enveloped within the microbiological target species. The microbiological target species may comprise cellular organisms such as bacteria, algae, fungi, prokaryotes, etc. or viruses. Target materials comprise intracellular nucleic acids, or in the case of viral sampling, nucleic acids encased within the protein sheath or coating of the virus.
