Which feature of Mycobacterium tuberculosis contributes to its virulence?
Understand the Problem
The question is asking which specific characteristic of Mycobacterium tuberculosis plays a role in its ability to cause disease. It presents several options to choose from, requiring knowledge of microbiology and the virulence factors of this bacterium.
Answer
The unique cell envelope and complex cell wall structure of Mycobacterium tuberculosis contribute to its virulence.
The unique cell envelope structure and composition, including the peptidoglycan layer, and complex cell wall of Mycobacterium tuberculosis contribute to its virulence by maintaining cellular integrity and aiding in pathogenesis.
Answer for screen readers
The unique cell envelope structure and composition, including the peptidoglycan layer, and complex cell wall of Mycobacterium tuberculosis contribute to its virulence by maintaining cellular integrity and aiding in pathogenesis.
More Information
The cell wall of Mycobacterium tuberculosis is highly complex and contains unique lipids and carbohydrates that allow it to evade the host immune response, contributing significantly to its ability to cause disease.
Tips
A common mistake is to overlook the importance of the entire cell wall structure, not just individual components, in contributing to virulence.
