Mycoplasmas are a specific and unique species of bacteria - the smallest free-living organism known on the planet. The primary differences between mycoplasmas and other bacteria is that bacteria have a solid cell-wall structure and they can grow in the simplest culture media. Mycoplasmas however, do not have a cell wall, and like a tiny jellyfish with a pliable membrane, can take on many different shapes which make them difficult to identify, even under a high powered electron microscope. Mycoplasmas can also be very hard to culture in the laboratory and are often missed as pathogenic causes of diseases for this reason.

The accepted name was chosen because Mycoplasmas were observed to have a fungi-like structure (Mycology is the study of fungi - hence "Myco") and it also had a flowing plasma-like structure without a cell wall - hence "plasma".

Perfect for microbiology. But we have to need of collection for DHA exam of medical laboratory technicians.

Mycoplasma do not have a cell. They only have a simple cell membrane but no cell wall.
