Old and new selective pressures on Mycobacterium tuberculosis
Daniela Brites1, Sebastien Gagneux
1Swiss Tropical and Public Health Institute, Basel, Switzerland.
Summary
Mycobacterium tuberculosis complex (MTBC) has co-evolved with humans for millennia, shaped by host immunity and demography. Emerging factors like HIV/TB and drug resistance may alter this long-term evolutionary balance.
Area of Science:
- Evolutionary biology
- Infectious diseases
- Human-pathogen interactions
Background:
- Tuberculosis (TB) is an ancient human disease caused by Mycobacterium tuberculosis complex (MTBC).
- MTBC evolution has been historically driven by host immune responses and human population dynamics.
- Recent selective pressures, including HIV co-infection and anti-TB drug use, have emerged.
Purpose of the Study:
- To discuss the impact of novel selective pressures on the long-term host-pathogen balance.
- To explore how HIV/TB and drug resistance may influence the future evolution of MTBC.
Main Methods:
- This study is a discussion and synthesis of existing knowledge.
- It reviews the evolutionary impact of host-pathogen interactions.
Main Results:
- Historical selective forces (immunity, demography) have shaped MTBC.
- New pressures (HIV, drug resistance) are emerging and their long-term effects are under investigation.
Conclusions:
- HIV/TB co-infection and drug resistance represent significant new selective pressures on MTBC.
- These factors may alter the evolutionary trajectory of MTBC and the future of human TB.

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.

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...

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...

01:32What is Natural Selection?
126.6K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor...

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:
