Neutrophils are also major players in the body's defense against bacterial infections. Neutrophils are made in the bone marrow and circulate in the bloodstream. Neutrophils move out of the blood vessels into the infected tissue to attack the bacteria. The pus in a boil (an abscess) is made up largely of neutrophils. Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher than normal white blood cell count (WBC).
