BACKGROUND The reactivation of tuberculosis arises in persons who are latently infected and in those who have been previously treated. The mechanism of the reactivation of tuberculosis in either situation is not well understood. A 13-gene mce1 operon of Mycobacterium tuberculosis was previously shown to be associated with latent infection in mice and may also play a role in reactivation. METH...
Tuberculosis (TB), a disease caused by the bacteria Mycobacterium tuberculosis (M. tuberculosis), is spread from person to person through the air. TB usually infects the lungs, but it can also infect other body parts such as the brain, kidneys, or spine. People who are infected by the bacteria but who do not exhibit symptoms have latent TB infection. It is estimated that one-third of the world’...
QuantiFERON-TB Gold obtained approval in 2003 by the Food and Drug Administration as a valid tool for the diagnosis of latent tuberculosis. In this report, we evaluated its potential use in the immunological diagnosis of Mycobacterium tuberculosis infections in different groups of subjects. Our data indicate that QuantiFERON-TB Gold is specific for identifying subjects who have come into contac...
BACKGROUND The 2050 Millennium Development Goals (MDG) for tuberculosis (TB) aim for elimination of TB as a public health issue. We used a mathematical modelling approach to evaluate the feasibility of this target in a low-prevalence setting with immigration-related strategies directed at latent tuberculosis. METHODS We used a stochastic individual-based model to simulate tuberculosis disease...
1. Latent EEects in a Hydrogeological Problem In the present study we investigate the data provided by the karstwater level monitoring system, set up in the Transdanubian Mountains, more precisely in the Bakony, the Keszthelyi Mountains and the Balaton-Highland. (Here, like in the sequel, the term karstwater is used for groundwater in karstic areas.) The detailed description of the monitoring s...
