IPA: /luːˈkoʊsɪdɪn/
KK: /lʊˈkoʊsɪdɪn/
A type of toxin produced by certain bacteria that kills or breaks down white blood cells, which are important for the immune system.
Leucocidin is known to contribute to the virulence of some bacterial infections by destroying the body's white blood cells.
Leucocidin is formed from "leuko-" (from Greek "leukos", meaning white) and "cidin" (from Latin "caedere", meaning to kill). The word refers to a substance that kills white blood cells.
Think of 'white' ('leuko-') and 'killing' ('cidin') to remember that leucocidin is a substance that kills white blood cells.
