Additional Information:
|
M. kansasii is an acid-fast, Gram-positive, non-motile, photochromogenic, rod-shaped and slow-growing nontuberculous mycobacterium frequently found in aquatic environments.2 It has traditionally been considered the most virulent nontuberculous mycobacteria closely resembling Mycobacterium tuberculosis; however, M. kansasii rarely causes disease in humans, is generally considered noncontagious and has a definite geographic distribution most common to the southern United States.3,4 Tap water is likely a major reservoir for M. kansasii causing human infection.3,5 Immunosuppression or immunodeficiency, abnormal skin or skin injury, and exposure to contaminated water are commonly associated with M. kansasii infection, which is usually susceptible to several antibiotics and can be treated effectively with a multidrug regimen.3,4,5
