Mycoplasma mollivute gram stain
Mycoplasma species are often found in research laboratories as contaminants in cell culture. Mycoplasmal cell culture contamination occurs due to contamination from individuals or contaminated cell culture medium ingredients. Mycoplasma cells are physically small – less than 1 µm, so are difficult to detect with a conventional microscope. Mycoplasmae may induce cellular changes, including chromosome aberrations, changes in meta… WebMycoplasma pneumoniae is a small bacterium which causes atypical pneumonia in young adults.. Mycoplasma, as a genus, have a cell membrane that is packed with sterols, but they lack a proper, rigid cell wall..
