as pseudomonas, acinetobacter, and staphylococcus that appropriate disinfection can reduce these pathogens. the aim of this study was to evaluate the effect of different disinfectants on gram-negative bacteria isolated from the surface of accidents and burn hospital in yazd. materials and methods: in this study, 240 samples were randomly collected from different parts of accidents and burn hosp...

background: serum procalcitonin (pct) levels differ in patients with bacterial or fungal infections and are significantly elevated in patients with gram-negative bacteremia. we evaluated the diagnostic accuracy of different inflammatory markers to discriminate sepsis caused by different pathogens. materials and methods: we included 328 episodes of bacteremia from 292 patients with sepsis and 31...

The antibacterial activity of ethanol extract of Zingiber officinale Roscoe (ginger) and its combination with different salts like CuSO4, ZnSO4 and MnCl2 was investigated. Both Gram positive and Gram negative bacteria were tested by agar diffusion method. The results showed that ethanol extract of Zingiber officinale gave the maximum zone of inhibition at 50mg/ml concentrations against Escheric...

Cultureable bacterial diversity of previously unexplored Siachen glacier, Pakistan, was studied. Out of 50 isolates 33 (66%) were Gram negative and 17 (34%) Gram positive. About half of the isolates were pigment producers and were able to grow at 4-37°C. 16S rRNA gene sequences revealed Gram negative bacteria dominated by Proteobacteria (especially γ-proteobacteria and β-proteobacteria) and Fla...

In many parts of the world there is a rich tradition in the use of herbal medicine for the treatment of many infectious diseases. Because of the side effects and the resistance that pathogenic microorganisms build against the antibiotics, much recent attention has been paid to extract the biologically active compounds from plant species used in herbal medicine. In this study different parts of ...

Two new Chitosan-based nanocomposite films were prepared: Chitosan /7% Ag nanoparticles (NPs) (NC1) and Chitosan/7% Ag NPs/5%Carbacylamidophosphate(NC2), in which the carbacylamidophosphate derivitive is N-Nicotinyl-N′,N″- bis(hexamethylenyl) phosphorictriamide (NHE) with the formula: C5H4NC(O)NHP(O)(NC6H12)2. X-ray Powder Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) ...

abstract background: the invasion of microorganisms into the bloodstream and spread to different parts of body can cause disruption the functions of vital organs and even death. the proper and prompt treatment is essential and can significantly reduce morbidity and mortality rates. this study aimed to determine the frequency and the antimicrobial susceptibility of bacteria isolated from blood c...

Thin films of pure zinc oxide (ZnO) and aluminium (Al) doped ZnO were deposited by two step SILAR technique. Pure Al (1%, 3%, 5%) thin film’s structural, morphology optical properties analyzed. Diffraction peaks all the samples indexed to hexagonal Wurtizite structure. The crystallite size, lattice parameters, dislocation density microstrain calculated for prepared films. Morphology study using...

Both N-doped and undoped thin films of 3SnO2/TiO2 composite were prepared, by sol-gel and dip-coating methods, and then calcined at 600 °C for 2 hours. The films were characterized by FTIR, XRD, UV-Vis, SEM, and XPS, and their photocatalytic activities to degrade methylene blue in solution were determined, expecting these activities to correlate with the inactivation of bacteria, which was conf...
