What is the pathogen that causes pertussis?

Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.

How does Bordetella pertussis reproduce?

Once the whooping cough bacteria are breathed in, they stick to cells in the nose and throat and the bacteria start to reproduce rapidly. As the bacteria reproduce, they produce toxins that paralyse cells in the windpipe and lungs that clear the airways of mucus and debris.

Why is it difficult to grow Bordetella pertussis in a laboratory?

Bordetella species are fastidious because their growth can be inhibited by components commonly found in laboratory media. In addition, their rate of growth is inversely related to their degree of fastidiousness. B. pertussis is the most fastidious and slowest growing of the Bordetella species.

Is whooping cough common in 2021?

No outbreak-associated and 1 household-associated case have been identified in 2021. For most pertussis cases, exposure to other known cases is not identified and are not able to be linked to outbreaks.
