What type of bacterium does Bordetella pertussis belong to?

Bordetella pertussis is a Gram-negative bacillus, also known as Bordetella pertussis. It is small and oval-shaped, lacks flagella and spores, and is strictly aerobic. This bacterium produces several pathogenic substances, such as pertussis toxin, which cause whooping cough, an acute respiratory infectious disease. Its resistance is weak; it is sensitive to drying and heat, and thus easily dies. Therefore, the key to preventing whooping cough lies in enhancing personal hygiene and immunization to reduce the risk of infection.
