What is mycobacterium malmoense?

Mycobacterium malmoense (M. malmoense) is a bacterium naturally found in the environment, such as in wet soil, house dust, water, dairy products, domestic and wild animals, food, and human waste.[1][2] M. malmoense infections most often occur in adults with lung disease, and manifests as a lung infection.[3][4] Skin and tissue infections with M. malmoense have also been described.[1] In young children, M. Malmoense may cause an infection of lymphnodes in the neck (i.e., cervical lymphadenitis).[1][4]

What are the signs and symptoms of mycobacterium malmoense infection?

Many cases of M. malmoense infection cause no symptoms, and as a result go unrecognized.[3] M. malmoense infections in adults often present as lung infections with or without fever. In children, M. malmoense infections can present as a single sided, non-tender, enlarging, neck mass. The mass may be violet in color and often does not respond to conventional antibiotic therapy.[4] M. malmoense infection can also cause skin lesions or abscesses.[4]

How are mycobacterium malmoense infections contracted?

M. Malmoense infection may be acquired by breathing in or ingesting the bacteria, or through trauma, such as an injury or surgical incision.[2] People who have suppressed immune systems are at an increased risk for developing signs and symptoms from these infections.[2]
