Plasmid DNA chromatography is a powerful field in constant development and evolution. The use of this technique considered mandatory the production an efficient safe formulation to be applied for plasmid-mediated gene therapy. Concerning this, search ideal chromatographic support/ligand combination motivated scientist pursue continuous improvement on plasmid performance, looking progression lig...

background and objectives: bacteria, most prevalently the pseudomonas species possess high capacity to utilize and de- grade petroleum hydrocarbons and are classified as the hydrocarbonoclastic microorganisms. many species of the genus pseudomonas are notorious for their aerobic degradation capacity, extracellular enzyme production and are metabolically versatile organisms capable of utilizing ...

This study was carried out to evaluate the plasmid mediated drugs resistance among wound bacteria isolates obtained from (352 swabs specimens) patients attending some hospitals in Kano State (National Orthopaedic Hospital Dala, Aminu Teaching Hospital, Infectious Diseases Bichi General and Wudil Hospital). Swab specimens were aseptically using randomized sampling method cultured on Blood MacCon...

The estuarine and coastal waters of Goa situated on the West coast of India, are known to be highly contaminated with arsenic. The rivers Mandovi and Zuari flowing through the iron and manganese mining areas are daily used for the transportation of over 300 barges of iron-ore to the harbour. However, studies related to the identification of ars genotype in arsenic-resistant bacteria inhabiting ...

the present study aimed to evaluate the antibiotic resistance pattern of escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. a total of 28 e. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of e. coli strains was determined by meansof disc diffusion assay. the resistance pattern determined for all stra...

Quinolone antibiotics have been commonly used to treat cases of multiple antibiotic resistance. Unfortunately, quinolone so much resisted by infectious bacterial agents. This study aimed evaluate the susceptibility some clinical isolates E. coli and determination plasmid-encoded resistance genes.
 Our results showed plasmid quinolone-resistance genes in following prevalence: qnr genes: S (...

pseudomonas aeruginosa is an important life-threatening nosocomial pathogen and plays a prominent role in serious infections in burned patients. the current study was undertaken to characterize p. aeruginosa strains isolated from burned patients in tehran, iran. the study was conducted in a major burn center in tehran, iran in 2007. a total of seventy specimens obtained from different clinical ...

background and purpose: brain-derived neurotrophic factor (bdnf) is present in the hippocampus and cerebral cortex in high concentrations and has an important role in development, maintenance and regeneration of the nervous system. the aim of this study was to produce active bdnf in e.coli using transforming plasmid. methods: to construct an expression plasmid of bdnf, a gene coding for it was ...

shigellosis is an acute gastroenteritis caused by shigella species. the purpose of this study was to determine plasmid profile, antibiotic resistance and phenotypic virulent by congo red between s. flexneri strains. the isolated bacteria were identified by standard bacterial and biochemical methods. plasmids were isolated by alkaline lysis method. antibiotic susceptibility test was performed ac...
