Abstract: This disclosure features methods of identifying an organism. The methods include: (a) obtaining a nucleic acid sample from an organism; (b) imaging said nucleic acid; (c) obtaining a restriction map of said nucleic acid; and (d) correlating the restriction map of said nucleic acid with a restriction map database, thereby identifying the organism.
Abstract: The invention generally relates to methods of identifying and categorizing organisms and more specifically methods of generating and using patterns of chromosomal variation in order to classify organisms.
Abstract: The present invention provides a method for organizing genomic information from multiple organisms. In one embodiment of the invention, phylogenetic trees can be constructed for the organisms. The method of the present invention is termed CAPO, Comparative Analysis and Phylogeny with Optical-Maps. Optical maps of organisms are obtained and phylogeny between the organisms is determined by optical map comparison and bipartite graph matching between the organisms, as, for example, computed by a stable marriage algorithm.

Abstract: The invention generally relates to methods and kits for isolating nucleic acids from an organism. In certain embodiments, methods of the invention involve contacting a plurality of lytic enzymes to an organism, thereby lysing a cell wall of the organism to release the nucleic acid, and introducing at least one agent to separate the nucleic acid from the lysed cells, thereby isolating the nucleic acid.
Abstract: The invention generally relates to methods of characterizing small nucleic acid molecules, such as plasmids or nucleic acid molecules obtained from a virus. In certain embodiments, the invention provides a method of characterizing a small circular nucleic acid molecule, the method including performing rolling circle amplification on a small circular nucleic acid molecule, thereby producing a concatamer, and generating an optical map of the concatamer, thereby characterizing the small circular nucleic acid molecule.
Abstract: This disclosure features, inter alia, methods for determining at least one property of a nucleic acid. The methods include: (a) fixing the nucleic acid on a planar surface; (b) digesting the nucleic acid into fragments with at least one enzyme; (c) imaging the nucleic acid; and (d) analyzing the imaged nucleic acid to determine the property of the nucleic acid, wherein no internal nucleic acid standard is added during the method.
Abstract: This disclosure relates to methods of determining an antibiotic resistance profile of a bacterium, and methods of treating a patient with a therapeutically effective antibiotic. The methods include comparing the restriction map of the nucleic acid with a restriction map database, and determining antibiotic resistance of the bacterium by matching regions of the nucleic acid to corresponding regions in the database.
Abstract: This disclosure features methods of identifying at least one organism from a heterogeneous sample. The methods include: (a) obtaining a nucleic acid from at least one organism in a heterogeneous sample; (b) imaging said nucleic acid; (c) obtaining a restriction map of said nucleic acid; and (d) correlating the restriction map of said nucleic acid with a restriction map database, thereby identifying at least one organism in the heterogeneous sample.
