Summary
This case report details a severe Mycobacterium chelonae (M. chelonae) pleuro-pneumonia in an 81-year-old man. Prompt anti-mycobacterial treatment improved radiological findings in this rare respiratory infection.
Area of Science:
- * Pulmonology
- * Infectious Diseases
- * Microbiology
Background:
- * Mycobacterium chelonae (M. chelonae) is an atypical mycobacterium rarely implicated in respiratory infections.
- * This report focuses on a patient with pre-existing bronchiectasis colonized by M. chelonae.
Observation:
- * An 81-year-old immunocompetent male presented with acute dyspnea and fever.
- * Radiological findings included right hydro-pneumothorax and cavitated alveolar opacities.
- * Diagnostic samples (pleural fluid, bronchial aspirate) were positive for M. chelonae exclusively.
Findings:
- * The patient received treatment with clarithromycin and amikacin for M. chelonae pleuro-pneumonia.
- * Initial radiological improvement was noted, but the patient's overall condition remained poor.
- * Prolonged anti-mycobacterial therapy (11 months) led to stabilization of pulmonary lesions.
Implications:
- * This case highlights M. chelonae as a potential pathogen in severe pleuro-pulmonary infections, even in immunocompetent individuals.
- * It underscores the importance of considering non-tuberculous mycobacteria in persistent respiratory infections unresponsive to standard antibiotics.
- * Successful management involved prolonged, targeted anti-mycobacterial therapy, emphasizing the need for accurate diagnosis and tailored treatment strategies.

01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
