title: [Antigenic activity of Bordetella pertussis during cultivation in liquid nutrient media].
abstract: The authors studied the antigenic activity of Bordetella pertussis during stab cultivation. For the first time there were revealed changes (oscillations) of antigenic activity: formation of 3 peaks of which the middle was the highest. A possibility of improving the quality of pertussis vaccine by using biomass at the height of the peak was experimentally founded.
