<prompt> All the statements about nontuberculous mycobacteria NTM, are TRUE, EXCEPT:NTM are ubiquitous in soil and waterNo human-to-human transmission of NTMDisseminated disease denotes significant immune dysfunctionPulmonary disease, is usually associated with systemic immunodeficiency.  <response>: Nontuberculous mycobacteria NTM survives in soil and water. Most NTM cause disease in humans only rarely. There is no human-to-human transmission of NTM. Disseminated disease denotes immune dysfunction eg:advanced HIV infection. Pulmonary disease is highly associated with pulmonary epithelial defects but not with systemic immunodeficiency. Ref: Harrison, Edition-18, Page-1367.
