Watch above a clasÂsic movie made by David Rogers at VanÂderÂbilt UniÂverÂsiÂty in the 1950s. It shows “a neuÂtrophil (a type of white blood cell) chasÂing a bacÂteriÂum through a field of red blood cells in a blood smear. After purÂsuÂing the bacÂteriÂum around sevÂerÂal red blood cells, the neuÂtrophil finalÂly catchÂes up to and engulfs its prey. In the human body, these cells are an imporÂtant first line of defense against bacÂteÂrÂiÂal infecÂtion. The speed of rapid moveÂments such as cell crawlÂing can be most easÂiÂly meaÂsured by the method of direct obserÂvaÂtion.” This comÂfortÂing video comes courÂtesy of the estate of David Rogers, VanÂderÂbilt UniÂverÂsiÂty.
