Generalized transduction of small Yersinia enterocolitica plasmids.
To study phage-mediated gene transfer in Yersinia, the ability of Yersinia phages to transduce naturally occurring plasmids was investigated. The transduction experiments were performed with a temperate phage isolated from a pathogenic Yersinia enterocolitica strain and phage mixtures isolated from sewage. Small plasmids (4.3 and 5.8 kb) were transduced at a frequency of 10(-5) to 10(-7)/PFU. H...
متن کاملCharacteristics of conjugative R-plasmids from pathogenic avian Escherichia coli.
Three of four virulent avian Escherichia coli isolates transferred a single large molecular-weight R-plasmid to two recipient E. coli strains. Antibiotic resistances transferred included streptomycin (two isolates) and streptomycin-tetracycline-sulfa (one isolate). Production of colicin and siderophores, complement resistance, and embryo lethality present in the virulent isolates were not trans...
متن کاملCharacterization of Pseudomonas aeruginosa derepressed R-plasmids.
A genetic study of conjugal transmissibility of two R-plasmids was undertaken in Pseudomonas aeruginosa. Conjugally derepressed mutants of the R-plasmids were isolated, and examination of 11 independent mutants revealed that 10 were recessive to the wild-type transfer repressor, whereas 1 mutant was cis dominant. Cross-repression was observed between the two R-plasmids, suggesting that they hav...
متن کاملCharacterization of pPCP1 Plasmids in Yersinia pestis Strains Isolated from the Former Soviet Union
Complete sequences of 9.5-kb pPCP1 plasmids in three Yersinia pestis strains from the former Soviet Union (FSU) were determined and compared with those of pPCP1 plasmids in three well-characterized, non-FSU Y. pestis strains (KIM, CO92, and 91001). Two of the FSU plasmids were from strains C2614 and C2944, isolated from plague foci in Russia, and one plasmid was from strain C790 from Kyrgyzstan...
متن کاملR plasmids in Corynebacterium xerosis strains.
Plasmids coding for resistance to chloramphenicol, erythromycin, kanamycin, streptomycin, and tetracycline have been found in strains of Corynebacterium xerosis isolated from patients with otitis media.
