   Oxidative Burst






In this video sequence, a human neutrophil senses, moves toward and ingests an ovoid yeast. The indicator dye nitroblue tetrazolium (NBT) demonstrates that the white cell is using its lethal oxidative ability to kill the yeast. Black and white time-lapse video has been color enhanced to show the degree and location of the oxidative burst.
