in the present study, we have reported the biological synthesis of silver nanoparticles (agnps) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (pbw343, triticum durum and aegilops tauschii )for the reduction of silver ions to silver nanoparticles. bioreduction of ag+ to ag0 was observed when aqueous extract augmented with silver nitrate (agno3) was incubated ...
A new method of detecting urease activity in Enterobacteriaceae was developed. An 8.5 cm filter paper disc impregnated with 20% urea and 0.5% bromocresol purple was placed on the surface of a glucose fermentation plate after inoculation with a multipoint replicator and overnight incubation. This method was compared with the commercially prepared Mast urea agar (Multipoint) and Fuscoe's Urea Pla...
This study was conducted for determination of antibacterial effect of Echinometra mathaei extraction on human disease bacteria. Samples were collected in Abu Mosa Island. Extraction operation was done by shell, spines, gonad and aristotle's lantern. Ethyl acetate, n-hexane and methanol were used for extraction operation respectively. Extraction effect of these organs was investigated on Vibrio ...
in this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. we prove a posteriori $ l^2(l^2)$ and error estimates for this method under minimal regularity hypothesis. test problem of an application of the wave equation in the laser is presented to verify the efficiency and accuracy of the method.
Previously, we showed that microbial susceptibility to antimicrobials in concentrations non-toxic for human cells in culture could be tested using the wet disc topical antimicrobial assay. In this report, wet disc assay and agar well diffusion assay results were compared testing the susceptibility of Ps. aeruginosa isolates from burn patients to concentrations of Polymyxin B non-toxic for cultu...
Mastitis is one of the most costly diseases in the dairy industry. The use of antibiotics in the treatment of mastitis Leads to bacterial resistance and health problems for consumers. This study aimed to determine the antibacterial properties of essential oil of Thymus vulgaris on the bacteria Staphylococcus aureus, Escherichia coli and Staphylococcus were agalactia. Antibacterial properties of...
Growth inhibition of Aspergillus fumigatus,Aspergillus flavus and Fusarum solani exposed to the essential oils including Thyme, Agastache and Satureja were studied. Disc Diffusion Method was used to evaluate the fungal growth inhibitory effects of the essential oils. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oils were determined and compared with ...
Activity of crude extracts from Brazilian cerrado plants against clinically relevant Candida species
BACKGROUND Medicinal plants have traditionally been used in many parts of the world as alternative medicine. Many extracts and essential oils isolated from plants have disclosed biological activity, justifying the investigation of their potential antimicrobial activity. In this study, the in vitro antifungal activity of six Brazilian Cerrado medicinal plant species were evaluated against clinic...
Enteric fever continues to be a major health problem in India and plasmid mediated resistance in Salmonella typhi is known since 1972. Sixty three strains of S. typhi were isolated from blood and bone marrow cultures at the microbiology laboratory of Sri Ramachandra Medical College and Research Institute, Chennai, during the period, March 2002 to September 2002. Susceptibility to ampicillin, co...
BACKGROUND Human salmonellosis continues to be a major international problem, in terms of both morbidity and economic losses. The antibiotic resistance of Salmonella is an increasing public health emergency, since infections from resistant bacteria are more difficult and costly to treat. OBJECTIVES The aims of the present study were to investigate the isolation of Salmonella spp. with the BAC...
