Lung abscesses are one of the most common lower respiratory tract infections worldwide and can seriously endanger life. However, pathogens associated with lung abscesses still cannot be detected quickly and accurately with the current microbial detection technology. Here, the case of a 53-year-old male with a lung abscess caused by oral bacteria is reported. After metagenomic next-generation sequencing was applied to identify the pathogenic microorganism, the patient recovered with precision medicine. Metagenomic next-generation sequencing is an important tool for the clinical diagnosis of infectious diseases caused by microorganisms and in guiding precision medicine.
