Abstract: Provided are methods, compositions and kits for depleting host nucleic acid in a biological sample, said sample having been previously obtained from an animal host.

Abstract: Provided is a method for depleting host nucleic acid in a biological sample, said sample having been previously obtained from an animal host, said method comprising the steps of (a) adding a cytolysin, or an active variant thereof, to said sample; and (b) carrying-out a process to physically deplete nucleic acid released from host cells within said sample or otherwise render such nucleic acid unidentifiable.

Abstract: The present invention provides a method for depleting host nucleic acid in a biological sample, said sample having been previously obtained from an animal host and having been subjected to treatment to lyse host cells present in the sample, and having been subjected to a treatment to deplete nucleic acid released from host cells within said sample or otherwise to render such nucleic acid unidentifiable, the method comprising: (a) depleting host mitochondria or host mitochondrial DNA (mtDNA) present in the treated sample; and (b) extracting and/or analysing remaining nucleic acid from the treated sample. Also provided is a related kit comprising reagents for performing the method. Further claimed is a method for isolating mitochondrial DNA after host cells have been lysed and host cell nucleic acids have been removed from the sample.

Abstract: The present invention relates to a multiplex in vitro nucleic acid amplification method for identifying a species of the Mycobacterium tuberculosis complex present in a sample. The method includes detecting the presence or absence of a plurality of nucleic acid molecule targets in the sample in one reaction, wherein at least one of the nucleic acid molecule targets is present in the genome of one or more, but not all, of the species of the Mycobacterium tuberculosis complex. The invention also includes kits containing primers or probes for conducting this method, nucleic acids useful for performing this method and diagnostic techniques using these nucleic acids.
