Mycoplasmas are pleomorphic bacteria. The lack of a cell wall causes them to stain Gram-negative. In culture, they form colonies with a typical fried-egg appearance. Mycoplasmas include several human pathogens, including M. pneumoniae (primary atypical pneumonia). Mycoplasma also does not follow the universal genetic code: UGA = tryptophan
