Health care workers humoral immune response against GLcB, MPT51 and HSPX from Mycobacterium tuberculosis.

Tuberculosis (TB) is one of the oldest human infectious diseases and one third of the world's population is latently infected. Brazil is an endemic area for TB. One of the most important challenges in TB control is the identification of latently infected individuals.

MPT-51/CpG DNA vaccine protects mice against Mycobacterium tuberculosis.

Tuberculosis (TB) is a severe infectious disease that kills approximately two million people worldwide every year. Because BCG protection is variable and does not protects adults, there is a great need for a new vaccine against TB that does not represent a risk for immunocompromised patients and that is also capable of protecting adult individuals. MPT-51 is a protein found in the genome of mycobacteria and binds to the fibronectin of the extracellular matrix, which may have a role in host tissue attachment and virulence.

Humoral response to HspX and GlcB to previous and recent infection by Mycobacterium tuberculosis.

Background: Tuberculosis (TB) remains a major world health problem. Around 2 billions of people are infected by Mycobacterium tuberculosis, the causal agent of this disease. This fact accounts for a third of the total world population and it is expected that 9 million people will become infected each year.
