white blood cell differential
Macrophages. Macrophages are monocytes that have gained the ability to phagocytize bacteria in the tissues. They are agranular because, when stained, they do not have granules in their cytoplasm. This is just a classification of leukocytes (or white blood cells).
Yes Leukocytes are nucleated.
Leukocytes don't eat good bacteria which is helpful and does good things to the body. Leukocytes eat bad bacteria which is harmful and makes people sick.
This process is used as a screening test for bacteria only.
white blood cell differential
A basophil is a cell which has granules stained by basic stains, especially granular leukocytes.
Because leukocytes are clear and colorless, they must be stained with an appropriate dye before a differential count is performed
fighting infections
Phagocytosis
Leukocytes are white blood cells. There are different kinds of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. During a differential leukocyte count, 100 white blood cells are counted on a Wright stained blood smear using a microscope and assigned to one type. The percent of leukocytes that fall into each type can be used to indicate what disease or condition a patient has. An increased number of neutrophils may indicate a bacterial infection. The presence of cancerous cells can also be determined.

Diapedesis
It directs leukocytes to the inflamed area
Eosinophils are the granular leukocytes that stain red. They are important elements of the body's immune defense against pathogens and allergens.
Leukocytes are part of the body, not separate organisms. As such they obtain their energy by metabolizing the sugars in the blood stream to produce needed energy. Strictly speaking, they do not "feed on" anything. They absorb and process sugars.
