Pulmonary disease caused by Mycobacterium malmoense.
The American Review of Respiratory Disease
|June 1, 1987
Summary
Mycobacterium malmoense caused pulmonary disease in two patients, meeting diagnostic criteria for mycobacteriosis. Further investigation is needed for two additional cases of M. malmoense isolation.
Area of Science:
- Medical Microbiology
- Pulmonary Medicine
- Infectious Diseases
Background:
- Mycobacterium malmoense is an atypical mycobacterium.
- Pulmonary infections caused by M. malmoense are uncommon, particularly in the United States.
Observation:
- M. malmoense was isolated from pulmonary samples of four patients.
- Two patients presented with progressive pulmonary disease and positive M. malmoense cultures, fulfilling diagnostic criteria for mycobacteriosis.
- In two other patients, M. malmoense isolation may represent colonization or an incidental finding.
Findings:
- This study reports on four cases of M. malmoense isolation from pulmonary material.
- Two cases were definitively diagnosed as pulmonary mycobacteriosis due to M. malmoense.
- The role of M. malmoense in the pulmonary disease of the other two patients remains uncertain.
Implications:
- Highlights the potential for M. malmoense to cause pulmonary disease in the US.
- Emphasizes the importance of considering atypical mycobacteria in pulmonary infections.
- Suggests a need for increased awareness and diagnostic vigilance for M. malmoense in clinical practice.
