    Structured Review

    ATCC x003899
    a) We conducted a serial dilution experiment in which we mixed two Mtb DNA standards representing lineage 4.1.2.1 (strain <t>X003899)</t> and 4.9 (strain H37ra), such that the minority strain represented 0-100% of the total DNA and then diluted Mtb DNA in human DNA, to simulate clinical samples which are overwhelmingly human DNA. We approximated the proportion of Mtb DNA found in sputum with smear microscopy grades 1+, 2+, and 3+. 7 We used hybrid capture to enrich for Mtb DNA, conducted whole genome sequencing of captured libraries on an Illumina platform. b) We additionally prospectively sampled matched Mtb diagnostic cultures and unprocessed sputum submitted to ARUP diagnostic laboratories. We performed hybrid capture and Illumina whole genome sequencing on matched samples.

    Article Snippet: To measure the efficiency of hybrid capture and accuracy of variant identification in captured samples, we created mixtures of reference strains H37Ra (ATCC 25177) and X003899 (ATCC BAA-2237D-2) with well characterized genomes (representing Mtb lineages 4 and 2), in which the minor strain comprised 0, 1, 2, 5, 10, 20, and 50% of the input DNA ( ).
