What is the size of pleuropneumonia-like organisms?

Pleuropneumonia-like organisms, also known as Mycoplasma, are among the smallest known free-living prokaryotes. They lack a cell wall, which contributes to their small size. The most commonly referenced size for Mycoplasma species is approximately 0.1 µm in diameter. This size allows them to pass through filters that would normally trap larger bacteria and contributes to their unique properties in terms of culture and detection.

This specific size is significant in clinical microbiology because it helps in understanding how these organisms can evade detection and treatment. Their diminished size compared to other bacteria is also related to their simplified structure and metabolic capabilities, which make them distinct in terms of pathogenicity and growth requirements. Understanding the microscopic dimensions of organisms like those causing pleuropneumonia is crucial for proper identification and treatment in medical contexts.
