  • Publication number: 20230154568
    Abstract: The present disclosure provides a method for identifying multi-copy regions in microorganism target fragments, which at least includes the followings: S100, searching for a candidate multi-copy region: performing an internal alignment on the microorganism target fragment, and searching for a region corresponding to a to-be-detected sequence of which the similarity meets a preset value as the candidate multi-copy region, the similarity being a product of a coverage rate and a matching rate of the to-be-detected sequence; S200, verifying and obtaining a multi-copy region: obtaining a median value of the copy numbers of the candidate multi-copy region; if the median value of the copy numbers of the candidate multi-copy region is greater than 1, the candidate is recorded as a multi-copy region. The method is high in accuracy and sensitivity. Undiscovered multi-copy regions can be identified even in incompletely assembled motifs. It is more comprehensive than 16srRNA which not always multi-copy.

  • Publication number: 20230154565
    Abstract: The present disclosure provides a method for obtaining species-specific consensus sequences of microorganisms, which at least includes the following operations: S100, searching for a candidate consensus sequence: clustering specific sequences of target strains belonging to the same species based on a clustering algorithm to obtain a plurality of candidate species-specific consensus sequences; S200, verifying and obtaining a primary screened species-specific consensus sequence: judging whether the candidate species-specific consensus sequences meet the following conditions: 1) the strain coverage rate meets a preset value; 2) the effective copy number meets a preset value; if the candidate meet all the conditions, determining that the candidate species-specific consensus sequences are species-specific consensus sequences.

  • Publication number: 20230129284
    Abstract: The present disclosure provides a method for identifying a specific region in a microorganism target fragment, including the following operations: S100, respectively comparing a microorganism target fragment with genome sequences of one or more comparison strain one-to-one, and removing fragments of which the similarity exceeds a preset value, to obtain a plurality of residual fragments as first-round cut fragments T1-Tn; S200, respectively comparing the first-round cut fragments T1-Tn with the remaining comparison strains, and removing fragments of which the similarity exceeds a preset value, to obtain a collection of residual cut fragments as a candidate specific region of the microorganism target fragment; and S300, verifying and obtaining a specific region. The method is high in accuracy and sensitivity which can identify the subspecies level and a dual-verification module is provided. The present disclosure is suitable for identifying a specific region in the whole genome of any pathogen.

  • Publication number: 20060007125
    Abstract: A user input device for use with an electronic instructional apparatus is disclosed as comprising a plurality of rods supported by a housing, a plurality of switch assemblies positioned along said rods and electrically connected to a control circuit, a plurality of objects rotationally disposed upon the rods and each overlying a switch assembly wherein a flange member within each object contacts and activates a switch when said object is rotated about the axis formed by said rod toward indicating which of the plurality of objects was manipulated by the user.
