The Oxidative Burst

In this sequence of microscope images, an amoeboid 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. These images are from black and white time-lapse video and have been color enhanced to show the degree and location of the oxidative burst.

A video clip of the oxidative burst is part of the "Immune System Collection" download.
