The conclusions of the method of the quantitative determination of pertussis bacilli in a suspension with the help of the complement fixation reaction is sufficiently sensitive and reliable. With this method it was possible to expose down to 250-500 million pertussis bacilli in 1 ml. For determining the concentration of pertussis bacteria in an experiment it is recommended to use the photocolorimetric method under the control of reactions which expose its specificity. The complement fixation reaction and the photocolorimetric method can be used for determining the concentration of pertussis bacilli in the air of a room and the extent of the inhaled dose of pertussis vaccine.
