L-Form Bacteria (cell wall deficient forms) in LBA

Appearance:
Also referred to as cell wall deficient forms (CWD’s), L-phase variants (and chondrits in pleomorphism), L-form bacteria are pleomorphic bacteria and can therefore assume a number of different shapes.
They spend a large part of their life cycle as tiny (about 0.01 microns in diameter) spherical forms, too small to be observed with a normal optical microscope.
At times, L-form bacteria can be observed breaking out of cells, where they can grow into long, thin biofilm filaments that can reach 60-70 microns in length. The biofilm filaments are composed of L-form bacteria and a protective protein sheath.
These bacteria lack a cell wall, which renders them very flexible and since they do not have flagella, their motion is very different from normal bacteria. They may also appear as more complex structures, with 3-4 spheres or donuts interconnected by a thin thread.
This appearance is most likely related to the bacteria replicating. Some classify the butterfly or disc-shaped bodies visible around some platelets as L-form bacteria, but these are more accurately classified as Pteroharpen.

“I thought the first module of the training was excellent and am looking forward to the next session. Elizabeth and Dr Okker have been wonderful to deal with.
I shopped around looking at systems and was so impressed with the quality of information they offered when making the initial enquiry. They have been so helpful throughout the entire purchasing process.
The added advantage of being able to study through Live Blood Online was also helpful cutting down on the need to travel overseas to study.
Being able to purchase a system and then be taught by the doctor who put the system together makes it feel complete and gives me as a practitioner beginning LBA some confidence and certainty.
So thank you Dr Okker and Elizabeth for your passion and knowledge on this amazing topic. I look forward to my microscope reaching New Zealand so I can begin to practice.
