is an obligate intracellular bacterium that primarily infects birds, but can cause respiratory infections in humans. Clinical evidence supporting the use of omadacycline for the treatment of pneumonia remains limited; therefore, this study aimed to evaluate the potential of omadacycline in treating pneumonia by analyzing the patients' clinical outcomes and the drug safety profile. We retrospectively reviewed the medical records of 15 patients with pneumonia treated at the First Affiliated Hospital, Zhejiang University School of Medicine between January and December 2023.
