Most effective bactericidal system within phagocytes is:
Lysozyme mediated
Lactoferrin mediated
Reactive oxygen metabolite mediated
Cationic basic protein mediated
The bactericidal action of phagocytes is based on NADPH oxidase induced respiratory burst producing superoxide. Ref: Cherie H. Dunphy, (2010), Chapter 38, "White Blood Cell and Immunodeficiency Disorders", In the book, "Molecular Pathology of Hematolymphoid Diseases", New york, Page 505
