Now these eosinophils are granulocytes that are specialized to fight certain parasites. So if the pathogen is parasitic then it's these cells that will ultimately end up fighting those parasites. Now neutrophils are basically a type of phagocytic cell. These neutrophils are capable of engulfing up to 20 bacterial cells before they actually die off. Now, when these phagocytic cells actually die off as a result of engulfing too many bacterial cells that is when we form our pus. So basically the nutrient fields are granulocytes recruited to the infected area and engulfed bacterial cells and other harmful agents and kills them intracellularly.
