Abstract:Medical microbiology focuses on the biological characteristics and pathogenesis of pathogenic microorganisms, mechanisms of human immune responses to infections, and pathogen diagnosis and prevention of infectious diseases. This discipline has evolved from morphology to molecular microbiology, microbiomics, microbial systems biology, and reverse microbial etiology at the knowledge level, while at the application level it encompasses genetic engineering, microbial gene manipulation, and microbial synthetic biology. This article reviews the recent advances in medical microbiology in terms of biological characteristics, pathogenicity, immunity, clinical pathogen diagnosis, prevention, and treatment. We should re-examine the relationship between microorganisms and human health, as well as microorganisms themselves, pay attention to microbiome data and knowledge system reshaping, and enhance public awareness of microorganisms. This review provides directions for the future development of medical microbiology.
