Abstract:
We encountered an extremely rare immunocompetent case of chronic pulmonary aspergillosis (CPA) caused by Aspergillus viridinutans. A 74-year-old woman was admitted with fever and hemoptysis. Chest computed tomography revealed a nodule in the left upper lobe. Bronchoscopy was performed, and the transbronchial biopsy specimen revealed Aspergillus fungi. Treatment of the nodule was initially ineffective with voriconazole but effective with liposomal amphotericin B. The causative organism was later identified as A. viridinutans based on the gene sequence of β-tubulin. This is the first immunocompetent case of CPA caused by A. viridinutans.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
