Bacteria
The image below illustrates a neutrophil with bacteria (Gram positive cocci). The major function of the neutrophil is to stop or retard the action of foreign matter or infectious agents. The neutrophil accomplishes this by moving to the area of inflammation or infection, phagocytizing (ingesting) the foreign material, and killing and digesting the material. Bacterial sepsis can result in a leukemoid reaction, involving white cell counts of 100,000 X 106/L (normal WBC=4,500 to 11,000 X 106/L), the presence of myelocytes, and the appearance of toxic granulation.This image was taken from a patient with Streptococcus pnemoniae infection.
