[Colicinogenotypes of Shigella sonnei strains isolated in the West Slovakian Region 1983-1988].

Using the method of colicinogenotyping by means of specific indicators, the author examined 1949 strains of Shigella sonnei isolated in 1983-1988 from patients with the diagnosis of bacillary dysentery in the capital of Slovakia Bratislava, as well as in other places in the West Slovakian region. Colicines accounted for 91.2% of the strains and were classified among 21 colicinogenotypes. Most frequently colicinogenotypes E6 were found (40.2%), E6, Ia (36.7%), E1 (7.9%) and E6, Ib (2.4%). There were 170 (8.7%) colicinogenic strains. As to the biochemical type, strains of colicinogenotype E1 belonged in 60.6% to biochemical type a, strains with colicinogenotype E6, E6, Ia and E6, Ib mostly to biochemical type d.
