Macrophage attacking Mycoplasma bacteria. Coloured transmission electron micrograph (TEM) of two Mycoplasma sp. bacteria (green), one of which has been engulfed by a macrophage white blood cell (grey). Mycoplasma are amongst the smallest bacteria known. They can cause pneumonia and urinary tract infections, and are resistant to some antibiotics. A macrophages is a type of white blood cell responsible for engulfing and destroying foreign organisms in a process called phagocytosis. In this, it extends pseudopodia (projections from its surface) around the organism, as seen at upper centre. Once engulfed, the organism is destroyed by enzymes. Magnification: x60,000 when printed 10cm tall.
