Abstract

The present invention relates to bacterial strains, in particular for use in the field of vaccines, in particular in the prevention or treatment of infections caused by Bordetella bacteria.

Description

technical field [0001] The present invention relates to the field of vaccines, in particular to the prevention or treatment of infections caused by bacteria of the genus Bordetella, in particular Bordetella pertussis. Background technique [0002] Pertussis, caused by the bacterium Bordetella pertussis, is a highly contagious airway infection. Acute infection can cause severe disease characterized by respiratory failure, pulmonary hypertension, leukocytosis, and death. Pertussis is a vaccine-preventable disease, and acellular pertussis (aP) or whole-cell pertussis (wP) vaccines are used worldwide. However, the disease persists in vaccinated populations, and epidemiological data report an increase in the incidence of pertussis worldwide in recent years. [0003] Several hypotheses have been postulated, including the evolution of pertussis strains and the shortened duration of protection of aP vaccines compared to wP vaccines. One area of ​​research aimed at controlling the...
