| [study of genomic polymorphism of shigella flexneri strains, isolated in various geographic regions]. | strains of shigella flexneri isolated from patients in 4 geographic regions of the former ussr have been studied by plasmid analysis and fingerprinting techniques. it has been shown that these methods make possible to differentiate phenotypically identical strains for 9 genotypic patterns (7 different plasmid profiles and 3 specific hybridization patterns). strains of shigella flexneri isolated from each region possess the similar hybridization patterns independent of serovar and plasmid profile ... | 1993 | 8510684 |
