سابقه و هدف: جیوه یکی از سمی ترین فلزات سنگین می باشد. مقادیر اندک جیوه برای همه موجودات زنده سمی است. با این وجود برخی از باکتری ها با مکانیسم های خاص در برابر جیوه مقاوم هستند. هدف از این پژوهش جداسازی و شناسایی باکتری های مقاوم به جیوه و بررسی ارتباط بین میزان آلودگی محیط به جیوه و احتمال جداسازی باکتری های مقاوم است. مواد و روش ها: نمونه برداری از آب و رسوبات چهار ایستگاه در طول رودخانه کر ...

Serratia marcescens ATCC 13880 is the type strain of the species and a commonly used quality control strain. Here, we present the annotated genome assembly of 5.13 Mbp (59.8% G+C content) as submitted to NCBI under accession no. JOVM00000000.

Phages infecting Serratia marcescens, a common causative agent of nosocomial infections, have potential therapeutic applications. Here, we report the complete genome of the novel S. marcescens phage BF, representing the third-largest phage genome sequenced to date.

The pigmented strain Serratia marcescens ATCC 274 had a higher buffering capacity and a higher membrane H conductance than S. marcescens GP, a spontaneous nonpigmented mutant of ATCC 274. The data suggest that mutations which apparently affect only the synthesis of a secondary metabolite can modify buffering capacity and passive H conductance.

We present a unique case of a patient who experienced recurrent infections of his implantable cardioverter defibrillator (ICD) site with the bacterium Serratia marcescens. This report highlights the virulence of this bacterium, its resistance to antibiotic therapy, and its ability to remain latent for prolonged periods between episodes of sepsis. It also demonstrates the merits of reimplanting ...

Morrison, D. A. (Harvard College, Cambridge, Mass.). Prodigiosin synthesis in mutants of Serratia marcescens. J. Bacteriol. 91:1509-1604. 1966.-Exchange of biosynthetic intermediates through the culture medium was used to characterize several hundred new color mutants of Serratia marcescens. The general scheme of prodigiosin synthesis as a bifurcated pathway, in which monopyrrole and bipyrrole ...

Serratia marcescens S2I7 is a heavy metal-resistant, polyaromatic hydrocarbon-degrading bacterium isolated from petroleum-contaminated sites. The genome contains one circular chromosome (5,241,555 bp; GC content 60.1%) with 4,533 coding sequences. The draft genome sequence includes specific genetic elements for degradation of hydrocarbons and for heavy metal resistance.

Over the last 30 years, Serratia marcescens has become an important cause of nosocomial infection. There have been many reports concerning the identification, antibiotic susceptibility, pathogenicity, epidemiological investigations and typing of this organism. Accurate identification is important in defining outbreaks. The API 20E system has been used widely, but is not individually satisfactor...

The nucleotide sequence of the proBA operon from a proline-hyperproducing mutant of Serratia marcescens was determined. Two base substitutions were found: one in theproBstructura1 gene, coding for y-glutamyl kinase (GK), and a second one in the promoter region of the operon. The former base substitution led to a change of the predicted amino acid at position 117 from an alanine to a valine in G...

From time to time, large volumes of bacteria may be required for purposes such as the isolation and identification of cellular components of metabolic products. Frequently a large quantity of one particular lot of cells is necessary so that enough replicates of an experiment may be performed to ensure a statistically valid result. For many reasons, replicate experiments may extend over consider...
