The white blood cell is attracted to the bacteria because proteins called antibodies have marked the bacteria for destruction. These antibodies are specific for disease-causing bacteria and viruses. When the white blood cell catches the bacteria it goes about eating it in a process called phagocytosis.David Rogers, Vanderbilt UniversityDeath is an Outrage!. The original video. It was made in the 1950s by David Rogers at Vanderbilt University.ollow Business Insider: Your body uses white blood cells to fight off the bacteria and viruses that invade your body and make you sick. In the gif below you can see a white blood cell called a neutrophil chase down a Staphylococcus aureus bacterium.
The blood has several types of white blood cells including neutrophils, bands, eosinophils, basophils, monocytes and lymphocytes. Each fights infection in a different way. Neutrophils, for example, are one of the body's main defenses against bacteria.Neutrophils kill bacteria by ingesting them.Neutrophils can ingest five to 20 bacteria in their lifetime. Another type of white blood cell is called bands.Bands are immature neutrophils. When a bacterial infection is present, an increase of both neutrophils and bands are seen. The eosinophil type of white blood cell kills parasites and has a role in allergic reactions.asophils release histamine (which makes blood vessels leak and attracts white blood cells) and heparin (which prevents clotting in an infected area so that the white blood cells can reach the bacteria). Monocytes enter the tissue itself, where they become larger. There they can ingest bacteria throughout the body.
