Background.Pasteurella species are a known zoonotic pathogen. Recently, the number of the reports of human infection has been increasing as the number of households keeping pets has increased. Case. A 66-year-old man with a family history of tuberculosis was referred to our hospital to undergo an investigation for abnormal shadows that were observed on a chest radiograph. Chest computed tomography showed centrilobular nodules in the right upper lobe. The patient was suspected of having pulmonary tuberculosis based on the shadows on the chest radiograph and his family history of tuberculosis. Sputum smears for acid-fast bacterium were negative, and an enzyme-linked immunospot assay was positive for tuberculosis. Pasteurella multocida was identified in his bronchial lavage fluid. We diagnosed the patient as having P. multocida lung infection. His lung infection improved following the administration of antibiotics. Conclusion. We herein reported a case of P. multocida lung infection that mimicked pulmonary tuberculosis.
