Which of the following options indicates the size of PPLO (Pleuro Pneumonia Like Organisms)?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. about 0.1 µm.

  1. PPLO (pleuro-pneumonia-like organisms), now known as Mycoplasma, is about 0.1 µm. These are among the smallest free-living organisms, lacking a cell wall and exhibiting extreme pleomorphism.
  2. Their tiny size allows them to pass through bacterial filters. Mycoplasma species are significant in veterinary and human medicine, causing diseases like bovine pleuropneumonia and atypical pneumonia in humans.
  3. Their minimal genome and simplicity make them key models in synthetic biology research.
