Nontuberculous mycobacteria (NTM) are opportunistic pathogens that are widely distributed in the environment. There is a lack of data on species distribution of these organisms from Iran. This study consists of a review of NTM articles published in Iran between the years 1992 and 2014. In this review, 20 articles and 14 case reports were identified. Among the 20 articles, 13 (65%) studies focus...

INTRODUCTION The infections due to Non-Tuberculosis Mycobacteria (NTM) are becoming an important health problem in many countries in the world. Globally, an increase in NTM infections has been reported from many countries around the world. However, limited information is available about the prevalence of NTM infections in Iran. MATERIAL AND METHODS The data of the prevalence of NTM infections...

A review of 20 studies and 14 case reports published in a recent issue of the journal from 14 provinces in Iran on clinical and environmental isolates of nontuberculous mycobacteria (NTM) showed M. fortuitum (229/997; 23%) as the most prevalent species from 1992 to 2014 [1]. The majority of NTM were collected from respiratory samples. The primary method of NTM detection was by culture using the...

non-tuberculosis mycobacteria (ntm), as certain species of mycobacteria, can affect human in several ways. in the preceding years, the rate of ntm detection has risen in both immunocompromised and immunocompetent patients. on the other hand, several reports have debated the possibility of co-infection of both mycobcateriu tuberculosis (mtb) and ntm in individuals that puts the role of ntm in di...

INTRODUCTION While NTM infection is mainly acquired from environmental exposure, monitoring of environmental niches for NTM is not a routine practice. This study aimed to find the prevalence of environmental NTM in soil and water in four highly populated suburbs of Tehran, Iran. MATERIAL AND METHODS A total of 4014 samples from soil and water resources were collected and studied. Sediments of...

Nontuberculous mycobacteria (NTM) can cause disease which can be indistinguishable from tuberculosis (TB), posing a diagnostic and therapeutic challenge, particularly in low- and middle-income settings. We aimed to investigate the mycobacterial agents associated with presumptive clinical pulmonary TB in Iran. A total of 410 mycobacterial isolates, obtained between March 2014 and January 2016, f...

Non-tuberculous mycobacteria (NTM) are among the emerging pathogens in immunocompromised individuals including hospitalized patients. So, it is important to consider hospitals water supplies as a source for infection. The aim of this study was to determine the prevalence of NTM in the hospital aquatic systems of Khuzestan, South west of Iran. In total, 258 hospital water samples were collected ...

Survival implications of nontuberculous mycobacterial pulmonary disease (NTM-PD) and NTM pulmonary isolation without disease (NTM-PI) are unclear. To study deaths associated with NTM-PD and NTM-PI and differences in survival between them, we conducted a population-based cohort study of persons with microbiologically defined NTM-PD or NTM-PI diagnosed during 2001-2013 in Ontario, Canada. We used...

BACKGROUND This study aimed to elucidate the phenotypic, immunologic, and clinical characteristics of Korean patients with nontuberculous mycobacterial (NTM) lung disease and compare them with non-NTM bronchiectasis (BE) patients. METHODS We prospectively recruited patients between 20 and 80 years of age who had nodular BE type NTM lung disease. Phenotypic, immunologic, and clinical character...

BACKGROUND The epidemiology of pulmonary nontuberculous mycobacteria (NTM) in Greece is largely unknown. OBJECTIVES To determine the incidence and the demographic, microbiological, and clinical characteristics of patients with pulmonary NTM infection and pulmonary NTM disease. METHODS A retrospective review of the demographic, microbiological, and clinical characteristics of patients with N...
