Mycoplasmas on HeLa cell. Coloured scanning electron micrograph (SEM) of a HeLa cancer cell infected with unidentified mycoplasmas (Mycoplasma sp., small bumps on cell surface). Mycoplasmas are bacteria that lack a cell wall. They commonly occur as parasites and pathogens (disease-causing organisms) in humans and other animals. Mycoplasmas often contaminate pure cultures of cells in the laboratory. HeLa cells are cancer cells originally derived from a patient with cervical cancer. They are cultured for use in cancer research. Magnification: x4200 at 6x9cm size.
