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.
