What is the main characteristic of Mycoplasma that causes joint inflammation?

Mycoplasma is categorized as a bacterium, and it has unique characteristics that differentiate it from other bacteria. One of its main features is that it lacks a cell wall, which is typically found in most other bacteria. This absence of a cell wall contributes to its pleomorphic nature, allowing it to take on various shapes, making it adaptable to different environments.

The involvement of Mycoplasma in joint inflammation, such as in conditions like reactive arthritis, is linked to its ability to evade the host immune response and establish persistent infections, which can lead to chronic inflammation. Understanding that Mycoplasma belongs to the bacterial kingdom is essential in comprehending its pathogenic mechanisms and how it interacts with the host's immune system. This classification as a bacterium is crucial for determining the appropriate diagnostic and treatment strategies for infections it may cause.
