Campylob acter r ectus Infection Leads to Lung Abscess: A Case Report and Literature Review

BACKGROUND: Campylobacter rectus is one of the anaerobic bacteria in the mouth. CASE PRESENTATION: We report the case of a 73-year-old man admitted for lung abscess caused by Campylobacter rectus with unique manifestations under electronic bronchoscopy, and the pathogen is first reported to be confirmed by metagenomic next-generation sequencing (mNGS) through testing bronchoalveolar lavage fluid. CONCLUSION: Sometimes, Campylobacter rectus can cause infection outside the mouth such as lung abscess. Most patients have good outcomes.
