Diversity of retron elements in a population of rhizobia and other gram-negative bacteria.

Genetic elements called retrons reside on the chromosome of Escherichia coli and the myxobacteria and represent the first reverse transcriptase-encoding element to be found in a prokaryotic cell. All known retrons produce a functionally obscure RNA-DNA satellite molecule called multicopy single-stranded DNA (msDNA). We report here the presence of msDNA-producing retron elements in a number of n...

Genetic tools for pseudomonads, rhizobia, and other gram-negative bacteria.

Gram-negative bacteria are extraordinarily diverse microorganisms that present a wide variety of characteristics worthy of genetic investigation. For historical reasons, the application of recombinant DNA technology to gram-negative bacteria in general has always lagged behind that of E. coli and its close relatives. However, the past 10 years have seen dramatic advances in the development of n...

beta-Glucuronidase (GUS) transposons for ecological and genetic studies of rhizobia and other gram-negative bacteria.

A series of transposons are described which contain the gusA gene, encoding beta-glucuronidase (GUS), expressed from a variety of promoters, both regulated and constitutive. The regulated promoters include the tac promoter which can be induced by IPTG, and nifH promoters which are symbiotically activated in legume nodules. One transposon contains gusA with a strong Shine-Dalgarno translation in...

Antibiotic Resistance Pattern of Gram-Negative Bacteria in Gorgan

Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...

Investigating 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...
