Campylobacter rectus infection leads to lung abscess: A case report and literature review

Abstract

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.
