title: [Study of the role of colicins in the formation of microbial association in experiments in chick embryos].
abstract: Experiments were conducted on chick embryos; conditions of formation of bacterial cenosis of Shigella sonnei and E. coli were reproduced. The role of colicinogenia in the formation of bacterial cenosis was demonstrated. An accumulation of colicines in high titres (1: 5120- 1:2560) in the chick embryonic cavity was noted in combined or separate cultivation of colicinogenic shigellae and E. coli. An intergenera transmission of the col-factor was traced in experiments on chick embryos. The data obtained served as foundation for recommendation of the accessible and economic model (chick embryos) for the in vivo study of colicinogenia of the enteric bacteria representatives.
