摘要

Mycoplasma represents a unique genus of prokaryotic bacteria distinguished by the absence of a cell wall, a characteristic that sets it apart from other bacteria. Within the Mollicutes class, phylogenetic analysis reveals three distinct categories: Spiroplasma, Mycoplasma and Acholeplasma. Mycoplasmas within Pneumoniae are recognized for their capacity to induce a range of diseases in both humans and animals, frequently impacting respiratory and reproductive health. The representative strains in Pneumoniae group, particularly the M. pneumoniae clusters, have garnered significant attention due to their remarkable ability to adhere to, invade, and traverse host cells. This ability is facilitated by specialized structures known as attachment organelles, which possess a unique cytoskeletal structure that supports a distinctive gliding motility mechanism. This mode of motility is distinct from that observed in eukaryotes and the majority of bacteria. The gliding machinery of Mycoplasma is a complex assembly consisting of both surface and internal components, including a terminal button, paired plates, and a structure resembling a bowl or wheel. The internal architecture of the attachment organelles provides the essential scaffold for the operation of this sophisticated motility system. Mycoplasma’s gliding motility is crucial for its infection process and its capacity to evade the host immune defenses. Understanding the role of this motility to immune evasion can offer profound insights into the pathogenesis of these bacteria, could pave the way for the development of more effective therapeutic strategies against diseases caused by Mycoplasma and related species.
