Lung abscess caused by the anaerobic pathogen Tannerella forsythia.
Odontogenic infections can spread to the respiratory tract. Despite the known role of Tannerella forsythia as the primary pathogen in periodontitis, the association between T. forsythia infection and risk of pneumonia or lung abscess remains unknown. In this report, we present a case of lung abscess caused by T. forsythia infection. The pathogen was detected by metagenomic next-generation sequencing (mNGS) in the bronchoalveolar lavage fluid of the patient. The clinical characteristics and possible mechanisms of the infection are discussed. T. forsythia is a conditional pathogen that can cause lung abscess in the presence of helper bacteria and reduced host immune status. The course of treatment should be personalized and might be longer than 3 months.
期刊介绍：
Respirology Case Reports is an open-access online journal dedicated to the publication of original clinical case reports, case series, clinical images and clinical videos in all fields of respiratory medicine. The Journal encourages the international exchange between clinicians and researchers of experiences in diagnosing and treating uncommon diseases or diseases with unusual presentations. All manuscripts are peer-reviewed through a streamlined process that aims at providing a rapid turnaround time from submission to publication.
