The multistage vaccine H56 boosts the effects of BCG to protect cynomolgus macaques against active tuberculosis and reactivation of latent Mycobacterium tuberculosis infection

The multistage vaccine H56 boosts the effects of BCG to protect cynomolgus macaques against active tuberculosis and reactivation of latent Mycobacterium tuberculosis infection.

It is estimated that one-third of the world's population is infected with Mycobacterium tuberculosis. Infection typically remains latent, but it can reactivate to cause clinical disease. The only vaccine, Mycobacterium bovis bacillus Calmette-Guérin (BCG), is largely ineffective, and ways to enhance its efficacy are being developed. Of note, the candidate booster vaccines currently under clinic...

Early events in Mycobacterium tuberculosis infection in cynomolgus macaques.

Little is known regarding the early events of infection of humans with Mycobacterium tuberculosis. The cynomolgus macaque is a useful model of tuberculosis, with strong similarities to human tuberculosis. In this study, eight cynomolgus macaques were infected bronchoscopically with low-dose M. tuberculosis; clinical, immunologic, microbiologic, and pathologic events were assessed 3 to 6 weeks p...

BCG vaccine and pulmonary tuberculosis

Tuberculosis (TB) is one of the most important public health problems in the world and has been declared as a global emergency by the World Health Organization (WHO) in 1993. Bacillus Calmette-Guérin (BCG) is one of the first developed vaccines to prevent TB. Unfortunately, BCG vaccine has had a limited duration of protection and has shown controversial and variable levels of efficacy, especial...

Reactivation of Latent Tuberculosis Infection

Evaluation and Comparison of Body Mass Index and Albumin Level in Patients with Active Tuberculosis and Latent Tuberculosis Infection

Introduction: Limited data are available on the relationship between nutritional status and tuberculosis. The aim of this study was to evaluate and compare the body mass index (BMI) and serum albumin level in patients with active tuberculosis (ATB) and latent tuberculosis (LTB). Materials and Methods: A cross-sectional study was conducted on 17 patients newly diagnosed with pulmonary TB  who we...
