title: [Cytopathogenic effect of E. coli cells containing heterogeneous human O(H) type antigen on human cells in culture].
abstract: Interaction of two enteropathogenic strains E. coli O55-K59 and human Hela cells containing O(H) isoantigen was studied. When E. coli strain No. 5789 containing heterologic antigen O(H) was added to HeLa cell culture the cytopathogenic effect with the microbial doses of 2 X 10(10), 2 X 10(5), 2X 10(4) was revealed on the third day of the interaction. A dose of 2 X 10(3) of E. coli microbes gave no such effect. Strain No. 3827 containing no heterologic antigen of ABO type failed to exert any cytopathogenic effect with maximal, mean, and minimal doses of the microbes. It is assumed that the cytopathogenic effect of strain No. 5789 is connected with the presence of the strain antigen identical to the group antigen of the human cell culture under study.
