Whole genome sequencing of Mycobacterium tuberculosis reveals slow growth and low mutation rates during latent infections in humans [PDF]

open access: yes, 2014
Very little is known about the growth and mutation rates of Mycobacterium tuberculosis during latent infection in humans. However, studies in rhesus macaques have suggested that latent infections have mutation rates that are higher than that observed ...

Tuberculosis and COVID-19 Dually Affect Human Th17 Cell Immune Response

open access: yesBiomedicines, 2023
COVID-19 infection not only profoundly impacts the detection of tuberculosis infection (Tbc) but also affects modality in tuberculosis patient immune response.

Cost-effectiveness of post-landing latent tuberculosis infection control strategies in new migrants to Canada.

open access: yesPLoS ONE, 2017
BackgroundThe majority of tuberculosis in migrants to Canada occurs due to reactivation of latent TB infection. Risk of tuberculosis in those with latent tuberculosis infection can be significantly reduced with treatment.

Determining Mycobacterium tuberculosis infection among BCG-immunised Ugandan children by T-SPOT.TB and tuberculin skin testing. [PDF]

open access: yes, 2012
BACKGROUND: Children with latent tuberculosis infection (LTBI) represent a huge reservoir for future disease. We wished to determine Mycobacterium tuberculosis (M.tb) infection prevalence among BCG-immunised five-year-old children in Entebbe, Uganda, but

Defining an intermediate category of tuberculin skin test: A mixture model analysis of two high-risk populations from Kampala, Uganda.

open access: yesPLoS ONE, 2021
One principle of tuberculosis control is to prevent the development of tuberculosis disease by treating individuals with latent tuberculosis infection.

Lack of immune responses to Mycobacterium tuberculosis DosR regulon proteins following Mycobacterium bovis BCG vaccination. [PDF]

open access: yes, 2007
Mycobacterium bovis BCG is widely used as a vaccine against tuberculosis (TB), despite its variable protective efficacy. Relatively little is known about the immune response profiles following BCG vaccination in relation to protection against TB. Here we

Tuberculosis State Is Associated with Expression of Toll-Like Receptor 2 in Sputum Macrophages

open access: yesmSphere, 2017
During tuberculosis, macrophages are critical for both pathogen survival and host immune activation. Since expression of particular cell surface markers reflects cell function, we used flow cytometry to measure the abundance of surface markers associated

Analysis of Mycobacterium tuberculosis-specific CD8 T-cells in patients with active tuberculosis and in individuals with latent infection. [PDF]

open access: yesPLoS ONE, 2009
CD8 T-cells contribute to control of Mycobacterium tuberculosis infection, but little is known about the quality of the CD8 T-cell response in subjects with latent infection and in patients with active tuberculosis disease.

Characterization of CD8 T cell responses in Mycobacterium Tuberculosis infection [PDF]

open access: yes, 2011
The aim of this project was to compare the breadth and magnitude of CFP10 and ESAT6-specific CD8 T cell responses in individuals with latent Mycobacterium tuberculosis (MTB) infection (LTBI) and active TB disease, and further define MTB-specific CD8 T ...

Tuberculosis Infection and Latent Tuberculosis

open access: yesTuberculosis and Respiratory Diseases, 2016
Active tuberculosis (TB) has a greater burden of TB bacilli than latent TB and acts as an infection source for contacts. Latent tuberculosis infection (LTBI) is the state in which humans are infected with Mycobacterium tuberculosis without any clinical symptoms, radiological abnormality, or microbiological evidence.
