Mixed Pulmonary Infection with Three Types of Nontuberculous Mycobacteria

Epidemiology of human pulmonary infection with nontuberculous mycobacteria.

A great deal of study has gone into the assessment of the epidemiology of NTM infection and disease in many different parts of the world. Review of the available studies provides insight into the frequency of this clinical problem as well as important limitations in current data. Study methods have varied greatly, undoubtedly leading to differing biases. In general, reported rates of infection ...

Pulmonary Infection and Colonization with Nontuberculous Mycobacteria, Taiwan, 2000–2012

We analyzed samples from 13,652 patients who had respiratory cultures positive for mycobacteria in Taiwan during 2000-2012 and found that 56.9% were positive for nontuberculous mycobacteria (NTM). Whereas annual prevalence of tuberculosis decreased during the study period, prevalence of NTM disease and colonization increased, particularly among older patients and male patients.

Changing Epidemiology of Pulmonary Nontuberculous Mycobacteria Infections

Nontuberculous mycobacteria (NTM) disease is a notifiable condition in Queensland, Australia. Mycobacterial isolates that require species identification are forwarded to the Queensland Mycobacterial Reference Laboratory, providing a central opportunity to capture statewide data on the epidemiology of NTM disease. We compared isolates obtained in 1999 and 2005 and used data from the Queensland n...

Epidemiology of infection by nontuberculous mycobacteria.

Pulmonary disease due to nontuberculous mycobacteria.

Nontuberculous mycobacteria (NTM) are increasingly associated with pulmonary disease. This is a worldwide phenomenon and one that is not related just to better diagnostic techniques or HIV infection. The mode of transmission of NTM is not well defined, but environmental exposure may be the major factor. While most exposed and infected individuals never acquire NTM disease, some ostensibly immun...
