This pictorial essay aims to provide general radiologists and radiology trainees with an overview of the CT imaging spectrum of pulmonary nontuberculous mycobacterial infection (NTM). After reading this pictorial essay, the reader will be able to: 1. Understand the imaging spectrum of the pulmonary manifestations of NTM. 2.

Non-Tuberculous Mycobacteria: Classification, Diagnostics, and Therapy I Porvaznik et al. Adv Exp Med Biol. 2016 Jul 12. (Treatment of Non-Tuberculous Pulmonary Mycobacteriosis).Nontuberculous mycobacteria. The group of nontuberculous mycobacteria (NTM), formerly called atypical or ubiquitous mycobacteria, contains over 150 species. NTM can be found ubiquitously in nature and show a broad diversity regarding where they can be found and how they adapted to certain environmental conditions.Diagnosing nontuberculous mycobacterial infections can be difficult because symptoms resemble those associated with other lung conditions, such as chronic bronchitis. Symptoms may include a cough that produces sputum or blood, fever, fatigue, weight loss, and night sweats.


The prevalence of nontuberculous mycobacteria (NTM) is high (approximately 13%) in sputum of patients with cystic fibrosis (CF), but the impact on lung disease is unknown. We followed 60 incident NTM-positive and 99 culture-negative patients with CF for 15 months and assessed clinical impact of NTM by FEV 1 and high-resolution computed tomography (HRCT) of the chest.Mycobacteria differ so strongly from other bacteria in their cell wall architecture and metabolism that they require specific diagnostic tests, i.e. stains, culture media, identification methods. Tuberculosis and leprosy are well-known diseases of mankind, but Buruli ulcer disease and nontuberculous mycobacterial diseases are gaining recognition as important diseases in specific settings.

Classification. Nontuberculous mycobacteria generally are free-living organisms that are ubiquitous in the environment. Important reservoirs include water (including tap water), soil, animals, and dairy products; they can also be found as colonizers of medical equipment such as endoscopes and surgical solutions.1 Person-to-person spread has not been reported.1 More than 125 species of NTM have.

Welcome to NTM Disease Week at the ATS. Our goal is to provide helpful information on NTM diseases to patients, their families and other interested persons. 'NTM' is an abbreviation for 'nontuberculous mycobacteria.' The mycobacteria are a special group of bacteria characterized by having waxy outer walls that help protect them.

Nontuberculous mycobacteria (NTM) represent a large group of opportunistic pathogenic bacteria whose source of infection is the environment. Although infections caused by NTM are not on the Centers for Disease Control and Prevention (CDC) reportable list, current estimates place the incidence of disease at 10 cases per 100,000, leading to an estimate of 30,000 new cases annually in the United.

The nontuberculous mycobacteria (NTM) exhibit heterogeneous pathogenicity in humans. Articles on known and potential human factors capable of producing susceptibility to NTM lung disease (NTMLD) were identified by a systematic search of the medical literature, and are reviewed in the present study. Patients with pre-existing structural lung disease are known to be at risk of NTMLD.

NONTUBERCULOUS MYCOBACTERIA. The Runyon classification of nontuberculous mycobacteria based on the rate of growth, production of yellow pigment and whether this. pigment was produced in the dark or only after exposure to light. It was introduced by Ernest Runyon in 1959 (Fig. 111).

Nontuberculous mycobacteria were initially isolated shortly after Mycobacterium tuberculosis was isolated in the 19th century ().Although multiple reports in the first half of the 20th century describe human infection by “unusual,” “unclassified,” or “anonymous” mycobacteria, it was not until the 1950s that larger series began to confirm the nontuberculous mycobacteria as true.

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.

Nontuberculous mycobacteria (NTM) are emerging pathogens that affect both immunocompromised and immunocompetent patients. The development of molecular methods has allowed the characterization of new species and the identification of NTM to the precise species and subspecies levels. The incidence and prevalence of NTM lung disease are increasing worldwide, and this syndrome accounts for the.

Nontuberculous mycobacteria (NTM) are bacteria that grow and survive naturally in water and in dirt. These bacteria have been classified as nontuberculosis to distinguish them from tuberculosis.
