What type of white blood cells fights against bacterial infections?

Neutrophils play a crucial role in the body's defense against bacterial infections. These white blood cells are part of the innate immune system and are the most abundant type of granulocytes. They respond quickly to sites of infection, where they are recruited to eliminate pathogens, particularly bacteria. Neutrophils achieve this through several mechanisms, including phagocytosis, where they engulf and digest bacteria, as well as the release of antimicrobial substances.

Their multi-faceted approach to combating bacterial intrusion makes neutrophils essential for a rapid immune response, especially during the early stages of infection. This responsiveness is key to preventing the spread of bacteria and supporting the healing process.
