Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein.

xxMikexx [17]

Answer:

Antibodies

Explanation:

Bordetella pertussis is an obligate human pathogen and is the etiological agent of whooping cough. It is known to be an opportunistic organism.

The pathogenic mechanism of Bordetella pertussis is also known as virulence factor. These virulence factors are known to include adhesins such as filamentous haemagglutinin, fimbriae and pertactin, which allow B. pertussis to bind to ciliated epithelial cells in the upper respiratory tract.

It is known to be the agent of whooping cough, a highly contagious respiratory disease, dramatic for infants and also for elderly and pregnant women.

In this case, the antibodies will be the response that is uniquely directed against the organism. It is said earlier that this organism is an opportunistic one, this means that it causes infection when the immunity is down. So, when the immunity is empowered , it will definitely fight against the organism
