Macrophage infected with Candida yeast spores, coloured transmission electron micrograph (TEM). The central macrophage (blue) has three Candida yeast spores (brown) germinating inside it. Macrophages are white blood cells of the immune system. Their role is to engulf and destroy foreign material. They are found in all tissues of the body. Overgrowth of yeasts can result in fungal infections such as thrush (candidiasis). Magnification: x5260 when printed at 10 centimetres across.
