Mycobacterium Malmoense Infection in A Previously Healthy Patient Living in A Low-Incidence Country

Mycobacterium malmoense infection is a bacterium naturally found in the environment, such as in wet soil, house dust and water. It is a slow-growing mycobacterium that was first isolated in 1977. This species presents unique challenges for diagnosis and treatment and continues to cause considerable morbidity and mortality if inadequately treated. The following case report describes a pulmonary manifestation caused by M. malmoense in a previously healthy Irish woman.
