Pertussis Disease and Transmission and Host Responses: Insights From the Baboon Model of Pertussis.

Pinto MV, Merkel TJ

Abstract

Whooping cough is a highly contagious, acute respiratory disease, caused by the Gram-negative bacterium Bordetella pertussis (Bp). Despite the introduction and widespread use of vaccines starting in the 1950s pertussis cases continue to be reported, with a significant global impact. The role of specific virulence factors in disease and the immune mechanisms associated with protection following natural infection or vaccination are still not completely understood. The recently-developed baboon model of clinical pertussis provides a valuable tool for the study of pertussis. Baboons infected with B. pertussis exhibit all of the manifestations of human pertussis including paroxysmal coughing, mucus production, leukocytosis and transmission. The establishment of this model provides the opportunity to address unanswered questions about the natural progression of this disease and host responses to infection and vaccination in a very relevant model. In this review, we present an overview of our knowledge of pertussis along with recent advances resulting from use of the baboon model. Remaining questions and future research directions are discussed. We hope that the knowledge gained through use of the baboon model of pertussis and clinical studies will allow the development of more efficacious vaccines, conferring long lasting protection against disease and transmission.
