The main difference between mycoplasma and phytoplasma is that the mycoplasma refers to pleuropneumonia-like organisms (PPLOs), which can be parasitic in humans, animals, and plants whereas the phytoplasma refers to mycoplasma-like organisms (MLOs), which can be parasitic in plant phloem tissue and some insects. 1996). Recall that fimbriae are hairlike protein bristles on the cell surface. Viruses are small submicroscopic particles whereas phytoplasmas are much larger and resemble bacterial cells without a cell wall or distinct nucleus. 1997.
