White Blood Cell Chases Bacteria

Description:  In this dramatic movie from the 1950's a neutrophil chases and engulfs a bacteria. White blood cells like this neutrophil are an important part of our immune system. They will migrate to a site of infection or inflammation through chemotaxis and eliminate invading microbes. This phenomenon will hopefully lead to a number of student questions like:  How does the white blood cell follow the bacteria? What happens once the microbe is engulfed? etc.
