METHOD OF OBTAINING PREPARATION BASED ON VACCINE STRAIN OF PLAGUE MICROBE Russian patent published in 2014 - IPC C12N1/04 C12N1/20 A61K39/02 

FIELD: chemistry.

SUBSTANCE: invention relates to field of biotechnology and deals with method of obtaining preparation based on vaccine strain of plague microbe. Claimed invention includes preparing inoculation native culture of plague microbe, concentration of microbe suspension, preparing vaccine suspension and obtaining dry form of preparation, with process of preparing inoculation culture including cultivation of microbes in liquid nutritional medium in flasks for 48 h at temperature 26…28°C and contibuous aeration with not less than 10 l min^-1. with passaged stabilised starting culture, obtained as a result of three successive passages through organism of guinea pigs and mixed with glycerol-lactose-polyglucinum liquid in ratio 2:1; for preparation of vaccine suspension used is optimised in component composition protective drying medium, lyophilisation being carried out with observance of the specified regimen.

EFFECT: claimed solution makes it possible to obtain product with higher activity with reduced duration of process of its manufacturing.
