  • Title: [Study of the mechanism of reduction of the virulence in the Shigella flexneri strains resistant to streptomycin].
    Author: Lycheva GA, Aleshkin GI.
    Journal: Zh Mikrobiol Epidemiol Immunobiol; 1977 Sep; (9):114-8. PubMed ID: 339620.
    Abstract:
    Streptomycin-resistant mutations in donor strains of E. coli K12 Hfr AB 313 and AT-13 are not associated with the action of the strA-gene limiting the suppression. Shigella mutations str-r obtained by the method described in this paper also failed to limit the suppression. Changes in the virulence observed in transmission strA region from the str-r strains of E. coli and shigellae used in this work were not connected with mutations limiting the suppression (with competent mutations).
