A culture medium composition for bacteria of the Bordetella genus comprises a nutrient medium containing cyclodextrin or a salt thereof in combination with an etherified derivative of D-glucose polymer having a molecular mass at least equal to 2,000. A process for culturing bacteria of the Bordetella genus with such a medium is also disclosed.

A method for the purification, solubilization and/or detoxification of protein antigens of bacteria of the Bordetella genus involves the use of a carbonate buffer having a pH of 8.3 to 11.6. An acellular anti-whooping cough vaccine containing active principles in this carbonate buffer is also disclosed.
