Neutrophils and macrophages attack and destroy bacteria. Neutrophils are mature cells that can ingest bacteria. Macrophages enter tissues and swell ingesting bacteria that is in the tissues and blood stream.
A macrophage is a type of white blood cell capable of engulfing and destroying harmful bacteria that have invaded the body
Macrophages
The seven types of leukocytes are: neutrophils, eosinophils, basophils, monocytes, macrophages, dendritic cells, and lymphocytes. Neutrophils, basophils, esinophils, monocytes and lymphocytes are the five most commonly thought of.
A Macrophage is a white blood cell, produced by Monocytes. Monocytes and Macrophages are both Phagocytes. These work as a part of the human immune system. They act in non-specific "innate" immunity defense and are able to initiate specific "cell-mediated" immunity. The role of a phagocyte is to engulf and "digest"/destroy cell debris or pathogens, such as viruses and bacteria. They are directly responsible for this process called phagocytosis. Macrophages also stimulate Lymphocytes and other immune cells that react to pathogens as what is called an "antigen-presenting" cell, also known as a histiocyte . Macrophages are located throughout the bloodstream, and may be "fixed" or they can be freely motile and capable of amoeboid-like movement.

Capable of inhibiting the growth or reproduction of bacteria. Different from bactericidal (capable of killing bacteria outright).
