Abstract
None:
We report a case of an adult male with a history of recurrent cough and chest pain for five years. Mycobacterium arosiense was identified in his alveolar lavage fluid, and whole-exome sequencing revealed heterozygosity for CD209 in this patient. After 17 months of combined antibiotic therapy, the patient recovered completely.
