Objective Analysis of pathogen distribution in intensive care unit (ICU)patients with infectious diseases based on metagenomic next generation sequencing (mNGS)data,providing a basis for clinical anti infection treatment. Method By reviewing and analyzing the results of mNGS reports of infectious diseases in Fuzhou,the etiological distribution in this area was discussed. Results A total of 1083 mNGS reports of infectious diseases were collected in this study,and the total detection rate was 85.50%. There are 172 kinds of pathogens and 1334 cases of pathogens. The species and number of bacteria detected are the most,followed by viruses. The number of Gram negative bacteria (60.29%) was more than that of Gram positive bacteria (39.71%). The first three Gram negative bacteria were Klebsiella pneumoniae (114 cases,22.75%),Acinetobacter baumannii (78 cases,15.57%),and Pseudo-monas aeruginosa (66 cases,13.17%);Gram positive bacteria were Enterococcus faecium (68 cases, 20.61%),Corynebacterium striatum (46 cases,13.94%)and Staphylococcus aureus (31 cases,9.39%). Candida albicans (79 cases,40.51%),Pneumocystis yersii (32 cases,16.41%)and Candida nearly smooth (16 cases,8.21%)were the top three fungi detected. DNA virus was the main virus detected, cytomegalovirus (71 cases,27.52%),human herpesvirus 1 (62 cases,24.03%)and Epstein-Barr virus (57 cases,22.09%)were the first three viruses detected;RNA viruses were human pegivirus virus (13 cases,43.33%),human coronavirus 229E (4 cases,13.33%),rhinovirus (3 cases,10.00%)and hu-man coronavirus HKU1 (3 cases,10.00%). Among atypical pathogens,psittacosis had the highest physical examination rate (11 cases,55.00%). Conclusion Gram negative bacteria are the main patho-gen in patients with infectious diseases in ICU,followed by viruses. Dynamic ICU monitoring of patho-gen distribution can help achieve reasonable and effective anti infection treatment.
