Spatial Epidemiology of Pulmonary Nontuberculous Mycobacteria in Hawaii

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 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 ...

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...

Pulmonary versus Nonpulmonary Nontuberculous Mycobacteria, Ontario, Canada

In Ontario, Canada, during 1998-2010, nontuberculous mycobacteria (NTM) from pulmonary sites comprised 96% of species/patient combinations isolated; annual rates of isolation and cases increased steadily. NTM isolates from nonpulmonary sites comprised 4% of species/patient combinations; annual rates and cases were temporally stable. NTM increases were driven exclusively by pulmonary isolates an...
