Pulmonary disease due to Mycobacterium malmoense
Journal of Clinical Microbiology
|August 1, 1984
Summary
A rare pulmonary disease caused by Mycobacterium malmoense was diagnosed in a US man. This marks the first documented human infection by this bacterium in the United States.
Area of Science:
- Medical Microbiology
- Pulmonology
- Infectious Diseases
Background:
- Mycobacterium malmoense is an atypical mycobacterium.
- Non-tuberculous mycobacteria (NTM) infections are increasingly recognized.
- Pulmonary disease from NTM can mimic tuberculosis.
Observation:
- A 43-year-old male patient presented with symptoms suggestive of pulmonary disease.
- The patient resided in Virginia, USA.
- Diagnostic samples included sputum and bronchial washings.
Findings:
- Mycobacterium malmoense was successfully isolated from the patient's respiratory samples.
- This case represents the first documented instance of human infection with Mycobacterium malmoense in the United States.
- The diagnosis was confirmed through microbiological culture.
Implications:
- This finding expands the known geographic distribution of Mycobacterium malmoense infections.
- It highlights the importance of considering atypical mycobacteria in the differential diagnosis of pulmonary disease in the US.
- Further surveillance and research are needed to understand the prevalence and clinical significance of Mycobacterium malmoense in the United States.
