Bordetella pertussis whole cell

Molecular classification: Bacterial cell, Antigen, Vaccine component

Overview

Bordetella pertussis whole cell refers to the use of the entire, inactivated bacterium Bordetella pertussis as an antigen or immunogen. This preparation is commonly used in research and historically formed the basis of early pertussis (whooping cough) vaccines. The inactivated cell presents a broad array of antigens to the immune system, stimulating a robust immune response. Key antigens include pertussis toxin (PT), adenylate cyclase toxin (ACT), filamentous hemagglutinin (FHA), pertactin (PRN), and fimbriae (FIM).

Other names: B. pertussis whole cellWhole-cell Bordetella pertussisInactivated Bordetella pertussisWhole-cell pertussis antigen

Mechanism of action

The inactivated whole cell preparation acts as an antigen, stimulating the immune system to produce antibodies and cellular immunity against Bordetella pertussis components. This pre-exposure allows the body to mount a faster and more effective response upon actual infection.
