FIELD: biotechnology.
SUBSTANCE: strain of bacteria Serratia plymuthica B-1288, a strain of bacteria Serratia plymuthica B-1297, a strain of bacteria Serratia plymuthica B-1296 and a strain of bacteria Serratia plymuthica B-1285 are proposed. These strains are deposited in the collection of bacteria, bacteriophages and fungi of the Federal State Institution of Science "State Research Centre of Virology and Biotechnology "Vector". When using the preparations on the basis of the proposed strains the neutralisation index of influenza virus o type A is 2.5-6.5 lg with the initial concentration of the virus of 102.5-6.5 lg TCD50/ml.
EFFECT: strains have antiviral activity against influenza virus of type A.
