Lung abscess by Actinomyces odontolyticus and Parvimonas micra co-infection presenting as acute respiratory failure

Abstract

To the best of our knowledge, this is the first case report of mixed infection with A odontolyticus and P micra, which caused acute respiratory failure in an immune-competent patient. Therefore, physicians should consider the possibility of these organisms as causative pathogens of a fulminant pulmonary infection even in an immune-competent patient.
