[Characterization of Escherichia coli donor-specific RNA-containing bacteriophages].
The biological properties of 9 clones of Ri bacteriophages isolated from sewage water in 1981 were studied. On the basis of the activity of Ri phages with respect to E. coli donor-specific strains K12, the type of negative colonies, the ultrastructure of the virion and its sizes, adsorption on the pili of host cells, the latent period, the amount of harvest obtained from one infected cell, the clones under study were classified with small spherical RNA-bacteriophages. The neutralization of Ri phages with antiphage sera to standard phages f2 and fr made it possible to classify them with the first serological group and to divide them into 3 subgroups.
