A phagolysosome is a cytoplasmic body formed by the fusion of a phagosome, or ingested particle, with a lysosome containing hydrolytic enzymes. The enzymes digest most of the material within the phagosome. After fusion, the food particles or pathogens contained within the phagosome are usually digested by the enzymes contained within the lysosome. Phagolysosome formation follows phagocytosis. It is common in immunological functions of macrophages and forms the home of several infectious agents including Leishmania.
