Respiratory Burst

Medical Definition: A large increase in oxygen uptake by neutrophils and most types of tissue macrophages through activation of an NADPH-cytochrome b-dependent oxidase that reduces oxygen to a superoxide. Individuals with an inherited defect in which the oxidase that reduces oxygen to superoxide is decreased or absent (GRANULOMATOUS DISEASE, CHRONIC) often die as a result of recurrent bacterial infections.
Guide Notes: "large increase in oxygen uptake by neutrophils & most types of tissue macrophages"
Previously Indexed: Oxygen Consumption (1976-1991)
