FIELD: microbiology, genetics of microorganisms.
SUBSTANCE: invention relates to methods for transduction of anthrax pathogen and closely related bacilli. Method for transduction of Bacillus anthracis and closely related bacilli involves incubation a mixture of bacteriophage with recipient cells taken in the definite ratio. After the first bacteriophage generation in 20 min the preparation of recipient cell receptors is added to the transducing system and the transducing system is inoculated on selective media. Invention describes a method for preparing receptors from recipient cells B. anthracis, B. thuringiensis and B. cereus. Using the proposed method provides the full-value substitution of antiphage serum in the transducing system for a cheaper and simple in preparing component, namely, the preparation prepared from recipient cell receptors that neutralizes phage effectively and prevents excessive death of the recipient strain cells in the transducing system.
EFFECT: improved method for transduction.
