Book excerpt: This book is a comprehensive and authoritative source on nontuberculous mycobacterial (NTM) pathogens and diseases and their appropriate management, with a focus on lung disease. NTM diseases, especially lung diseases, are increasing in prevalence in the U.S. and internationally with concomitant growing interest in a broad section of the medical community. Often merely included in coverage of tuberculosis, many aspects of NTM organisms and diseases are actually very different than TB. These differences are not intuitive or trivial and frequently result in suboptimal management of NTM patients. This book addresses these gaps in the literature with chapters on microbiology, pathophysiology, epidemiology, the various diseases that can stem from NTM, and their particular management. There is also coverage on prevention and NTM as a public health problem. For pulmonologists and infectious disease physicians, this is the definitive resource on nontuberculous mycobacteria.
