Pseudomonas streptomycin resistance transposon associated with R-plasmid mobilization.
Plasmid pMG1 encodes resistance to gentamicin, streptomycin, sulfonamides, and mercuric ions and also mobilizes pRO161, a transfer-deficient plasmid derived from RP1. Upon mobilization, pRO161 acquires streptomycin resistance (Smr) and can subsequently be remobilized by pMG1 at significantly higher frequencies than pRO161 itself. Both the initial acquisition of Smr and the subsequent mobilizati...
متن کاملDetection of the Efflux-Mediated Erythromycin Resistance Transposon in Streptococcus pneumoniae
BACKGROUND The present analysis focuses on phenotypic and genotypic characterizations of efflux-mediated erythromycin resistance in Streptococcus pneumoniae due to an increase in macrolide resistance in S. pneumoniae worldwide. METHODS We investigated the prevalence of efflux-mediated erythromycin resistance and its relevant genetic elements from 186 specimens of S. pneumonia isolated from cl...
متن کاملHomology of a transferable tetracycline resistance determinant of Clostridium difficile with Streptococcus (Enterococcus) faecalis transposon Tn916.
In several tetracycline-resistant (Tetr) Clostridium difficile strains, homology with the Tn916 part of plasmid pAM120 DNA was observed. This 15-kilobase transposon, carrying a Tetr determinant, was originally found in Streptococcus (Enterococcus) faecalis. Hybridization experiments revealed that at least six of seven HincII fragments of Tn916, representing greater than 95% of its length, showe...
متن کاملPlasmid-determined resistance to erythromycin: comparison of strains of streptococcus faecalis and streptococcus pyogenes with regard to plasmid hmology and resistance inducibility.
Streptococcus faecalis strains DS-5 and Streptococcus pyogenes strain AC-1 both have a 17 million dalton plasmid that determines resistance to erythromycin, lincomycin, and vernamycin B(alpha). The results of deoxyribonucleic acid-deoxyribonucleic acid hybridization experiments indicate that the two plasmids are about 95% homologous. It was also shown that erythromycin resistance is inducible i...
متن کاملPlasmid and transposon transfer to Thiobacillus ferrooxidans.
The broad-host-range IncP plasmids RP4, R68.45, RP1::Tn501, and pUB307 were transferred to acidophilic, obligately chemolithotrophic Thiobacillus ferrooxidans from Escherichia coli by conjugation. A genetic marker of kanamycin resistance was expressed in T. ferrooxidans. Plasmid RP4 was transferred back to E. coli from T. ferrooxidans. The broad-host-range IncQ vector pJRD215 was mobilized to T...
