The invention relates to a
pathogenic microorganism genome database and an establishment method thereof, and belongs to the technical field of meta-genomes. The method comprises the following steps ofdata acquisition, wherein
pathogenic microorganism genome data is obtained; strain
genome screening, wherein species strain genomes are selected according to a predetermined screening rule;
plasmid sequence removal, wherein
plasmid sequences existing in the strain genomes obtained in the last step are removed;
filtration, wherein according to a predetermined filtering rule, strains with incorrectlabeling information, incomplete
chromosome assembly and incorrect classification are removed to obtain a reference strain genome of the species; fusion genome construction, wherein the reference strain genome is interrupted, redundancy is removed, reassembly is performed, and the sequences are reassembled to obtain a fusion genome of the species;
database assembly, wherein the above steps are repeated to obtain the fusion genome of the predetermined species, summary is performed, and the
pathogenic microorganism genome database is obtained. The
genome database has the advantages of not onlyhaving a high precision rate, but also having short analysis time and reducing the cost.
