Watch a Human White Blood Cell Chase Bacteria Through a Field of Red Blood Cells

Watch above a clas­sic movie made by David Rogers at Van­der­bilt Uni­ver­si­ty in the 1950s. It shows “a neu­trophil (a type of white blood cell) chas­ing a bac­teri­um through a field of red blood cells in a blood smear. After pur­su­ing the bac­teri­um around sev­er­al red blood cells, the neu­trophil final­ly catch­es up to and engulfs its prey. In the human body, these cells are an impor­tant first line of defense against bac­te­r­i­al infec­tion. The speed of rapid move­ments such as cell crawl­ing can be most eas­i­ly mea­sured by the method of direct obser­va­tion.” This com­fort­ing video comes cour­tesy of the estate of David Rogers, Van­der­bilt Uni­ver­si­ty.
