Transmission electron micrograph of a macrophage cell (blue) with 3 Candida yeast spores (brown) germinating inside. Macrophages are white blood cells of the immune system which 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). Horizontal image width is 19 microns.
