Pathogenic microorganism analysis and identification system and application thereof

The invention discloses a pathogenic microorganism analysis and identification system and application thereof. The system comprises a data statistics module, a sample management module, an experiment management module, an information analysis module, a report management module and a system management module. The information analysis module comprises a sample analysis sub-module and is used for realizing a data quality control step, a host removal step, a sequence classification step, a classification credibility index calculation step and a non-pathogenic bacterium filtering step; the credibility is screened by adopting species level, genus level reads number, species level unique Kmer number, corresponding species genome size, reads coverage size, read-containing window number and microbial genome reference genome according to the reads number. According to the application, the mNGS original offline data automatic analysis is realized through each module, the reliable classification result is obtained accord
