Bacterial strain Shigella sonnei, used as an indicator for typing colicins group E3 (E3, E4, E5, E6)

摘要

FIELD: microbiology, in particular indicator strain for identification of E₃ (E₃, E₄, E₅, E₆) colicines.;SUBSTANCE: invention relates to strain having sensitivity to group E₃ (r.E₃) colicines useful in gene typing of enteric bacteria, namely differentiation thereof on the base of produced colicines. Shigella sonnei strain is obtained by gene-and selection methodologies and represents mutant of typical Frederick Sh. sonnei P₉ strain being sensitive to group E₃ (E₃, E₄, E₅, E₆) colicines.;EFFECT: Sh. Sonnei strain useful in detection of single colicines or combination thereof in enteric bacteria.;5 tbl, 1 ex
