Clinical diagnosis of modern pertussis is difficult because of the widespread occurrence of mild and stigmatized forms of the infection. The main method of laboratory diagnosis of the disease is bacteriological analysis. However, it has many disadvantages, the main of which are low excretion of the pathogen due to late examination dates and non-standardization of various series of commercially available DHA medium produced by the Dagestan Research Institute of Nutrient Medium, as well as duration and laboriousness of the study due to the need for repeated analyses.
