FIELD: biotechnology, microbiology.
SUBSTANCE: invention relates to the asporogenous recombinant strain B. anthracis 55ΔTPA-1Spo- (pUB110PA-1) producing the anthrax microorganism protective antigen that is obtained by transformation of the strain B. anthrax 55ΔTSpo- with DNA of hybrid plasmid pUB110PA-1. The strain is deposited in GK of pathogenic "Mikrob" at number KM-97, and this the strain is characterized by absence of ability for spores formation, stability of hybrid replicon and high level of production of the protective antigen that represents the main component of chemical anthrax vaccines.
EFFECT: valuable biological of strain.
