Phagocytes are the white blood cells that protect the body by ingesting harmful foreign particles such as bacteria and dead cells. Also they are essential for fighting infections and for subsequent immunity. Phagocytes are crucial in fighting infections, as well as in maintaining healthy tissues by removing dead and dying cells that have reached the end of their lifespan. During an infection, chemical signals attract phagocytes to places where the pathogen has invaded the body. These chemicals may come from bacteria or from other phagocytes already present. Hope this will help!

Bacteria within inflamed tissues are usually destroyed by phagocytes. The purpose of phagocyte cells is to protect the body from bacteria as well as other foreign particles.
When harmful bacteria enter your body and produce toxins, an infection occurs. This can damage tissues and disable bodily functions.
Kidney infection, also called pyelonephritis and upper urinary tract infection, occurs when microbes, usually bacteria, invade the tissues of the kidney and multiply.
antigen- any substance the body regards as foreign
Pasteurellosis is characterized by inflammation around the wound site and may be accompanied by bacteria in the bloodstream and infection in tissues and organs
Cellulitis is a skin infection caused by bacteria. Normally, your skin helps protect you from infection. But if you have a cut, sore, or insect bite, bacteria can get into the skin and spread to deeper tissues. If it is not treated with antibiotics, the infection can spread to the blood or lymph nodes. This can be deadly.
A toxin is a substance that can injure living tissues. Toxins may be natural (e.g. from plants or bacteria) or human-made.

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).
