FIELD: biotechnology, veterinary science.
SUBSTANCE: invention relates to the strain that is deposited in the Collection of strain-pathogens of diseases in fur animals in the Museum of bacterial and viral structures of the Science-Research institute of fur farming and rabbit farming (NIIPZK) named for V. A. Afanasiev and has the registration number 71. The strains relates to streptococci of the group B. The strain is cultures in Todd-Hewite beef-extract broth, Pike medium at 37°C for 18-20 h. After control of the grown culture for virulence the separated biomass is inactivated by addition of 0.5% formaldehyde followed by addition of aluminum hydroxide as an adjuvant and packaging. Invention provides preparing the effective vaccine against streptococcosis in fur animals based on this strain.
