Summary
Tuberculosis (TB) remains a deadly infectious disease, worsened by drug-resistant strains and HIV co-infection. Current vaccines are ineffective, necessitating urgent development of new TB vaccines for prevention and immunotherapy.
Area of Science:
- Immunology
- Infectious Diseases
- Vaccinology
Background:
- Tuberculosis (TB) is the second leading infectious cause of death globally.
- Emergence of multi-drug resistant (MDR) and extensively drug-resistant (XDR) TB strains, alongside HIV co-infection, exacerbates the global TB burden.
- The Bacillus Calmette-Guérin (BCG) vaccine, used for a century, offers limited protection against adult pulmonary TB and poses risks in HIV-positive individuals.
Purpose of the Study:
- To review the current global prevalence of TB.
- To discuss the complex interaction between Mycobacterium tuberculosis (M. tb) and the host immune system.
- To highlight recent advancements in TB vaccine research and development.
Main Methods:
- Literature review of TB prevalence and epidemiology.
- Analysis of host-pathogen interactions in TB.
- Survey of current TB vaccine candidates and development strategies.
Main Results:
- Global TB rates are increasing, driven by drug resistance and HIV.
- BCG vaccine limitations include lack of efficacy in adults and safety concerns in immunocompromised populations.
- Significant research efforts are underway to develop novel TB vaccines.
Conclusions:
- Existing TB vaccines are insufficient for controlling the global epidemic.
- Understanding M. tb and host immunity is crucial for effective vaccine design.
- New vaccines are critically needed for TB prevention and immunotherapy.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
