Abstract: Disclosed herein is a method including one or more of amplifying a nucleic acid sequence of interest in a sample comprising genomic DNA of a subject; amplifying a reference nucleic acid sequence in the sample; quantifying the amplified sequence of interest relative to the amplified reference sequence; and determining a copy number of the sequence of interest from the relative quantified amplified sequence of interest. The reference sequence can have at least 80% sequence identity to at least one of SEQ ID NO:1-38. Also disclosed are kits, systems and compositions that can include a first probe which specifically hybridizes to at least a portion of at least one reference sequence.

Abstract: The present disclosure provides compositions and methods, as well as combinations, kits, and systems that include the compositions and methods, for amplification, detection, characterization, assessment, profiling and/or measurement of nucleic acids in samples, particularly biological samples. Compositions and methods provided herein include combinations of microbial species target-specific nucleic acid primers for selective amplification and/or combinations of primers for amplification of nucleic acids from a large group of taxonomically related microorganisms. In one aspect, amplified nucleic acids obtained using the compositions and methods can be used in various processes including nucleic acid sequencing and used to detect the presence of microbial species and assess microbial populations in a variety of samples. In accordance with the teachings and principles, new methods, systems and non-transitory machine-readable storage medium are provided to compress reference sequence databases used in mapping sequence reads for analysis and profiling of microbial populations.
