title: [Comparative study of non-conjugative R-plasmids from enterobacteria and Pseudomonas aeruginosa].
abstract: Nonconjugative R-plasmids pBS76 and pBS94 (Sm Su), pBS95 and pBS96 (Sm Su Ap) isolated from clinical strains of Pseudomonas aeruginosa and plasmids pKMR281-pKMN284 (Sm Su), pKMR285-pKMR286 (Sm Su Tc) isolated from clinical strains of enterobacteria have been studied. Restriction maps of these plasmids are presented in the paper with some of plasmid genes for antibiotic resistance localized on them. The resistance determinants of plasmids pBS95 and pBS96 are shown to be included in transposon Tn3612 analogous to Tn3. Plasmids pBS76, pBS94-96 are of the wide host range and belong to incompatibility group P4 (IncQ). Plasmids pKMR281-pKMR286 are mutually incompatible and share the conspicuous DNA homology. They are inherited only by enterobacteria and are compatible with IncQ plasmids but in contrast to them are mobilized by RP4 plasmid with lower frequency.
