Conjugative plasmid transfer in gram-positive bacteria.
Conjugative transfer of bacterial plasmids is the most efficient way of horizontal gene spread, and it is therefore considered one of the major reasons for the increase in the number of bacteria exhibiting multiple-antibiotic resistance. Thus, conjugation and spread of antibiotic resistance represents a severe problem in antibiotic treatment, especially of immunosuppressed patients and in inten...
متن کاملInvestigating the Antimicrobial Efficacy of Liposomal Vancomycin in Gram-positive and Gram-negative bacteria- A Preliminary Mechanistic Study
Outer membrane of Gram-negative bacteria is a permeability barrier to many antibacterial agents, including the glycopeptide antibiotics such as vancomycin hydrochloride and as a result these antibiotics are ineffective against Gram negative bacteria. Different strategies have been described to overcome such limitation, including application of nanoparticles, as was shown in our previous studies...
متن کاملNatural transfer of conjugative transposon Tn916 between gram-positive and gram-negative bacteria.
The conjugative streptococcal transposon Tn916 was found to transfer naturally between a variety of gram-positive and gram-negative eubacteria. Enterococcus faecalis hosting the transposon could serve as a donor for Alcaligenes eutrophus, Citrobacter freundii, and Escherichia coli at frequencies of 10(-6) to 10(-8). No transfer was observed with several phototrophic species. Mating of an E. col...
متن کاملSynthesis and Characterization of Novel Antibacterial PDDA/Honey Nanofiber Against Gram-Positive and Gram-Negative Bacteria
Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial na...
متن کاملPresence and dissemination of the multiresistance gene cfr in Gram-positive and Gram-negative bacteria.
The emergence of the multiresistance gene cfr in staphylococci is of global concern. In addition to conferring resistance to phenicols, lincosamides, pleuromutilins, streptogramin A antibiotics and selected 16-membered macrolides, the cfr gene also confers resistance to the oxazolidinone linezolid. Linezolid is a last-resort antimicrobial agent for the treatment of serious infections in humans ...
