pseudomonas aeruginosa is an important opportunistic pathogen causing widespread infections by numerous virulence factors. increasing resistance to antibiotics makes the pseudomonas infections treatment further difficult. the purpose of this study was to evaluate antimicrobial characteristics of essential oils from matricaria chamomilla, artemisia persica, zataria multiflora, myrtus communis, r...

Red River Gum (Eucalyptus camaldulensis) is a tree of the genus Eucalyptus widely distributed in Algeria and in the world. The value of its aromatic secondary metabolites offers new perspectives in the pharmaceutical industry. This strategy can contribute to the sustainable development of our country. Preliminary tests performed on the essential oil of Eucalyptus camendulensis showed that this ...

Methanolic leaf extracts of Eucalyptus camaldulensis were investigated for in vitro antifungal activities against Microsporum canis, Microsporum gypseum, Tricophyton rubrum, Tricophyton schoenleinii, Tricophyton mentagrophytes and Epedermophyton floccosum. The studies were carried out using broth dilution method, agar dilution method and inhibitory zone estimation. The effects of the plant extr...

In this study, a large number of wood samples from several species of Eucalyptus, including E. grandis, E. urophylla, E. globulus, E. dunnii, E. camaldulensis and their crossing were characterized by pyrolysis-GC/MS method. All the measurements were done directly from the Eucalypus wood samples. S/G ratios were calculated for all guaiacyl and syringyl lignin pyrolysis derivatives. The results w...

Because of its resistance to antibiotics, Staphylococcus aureus causes many of problems in hospital and society. As one of the main reasons of clinical infections it can cause to serious surgical and cutaneous infections and pneumonia. The inhibitory effect of the essential oils include; Eucalyptus largiflorence, E. camaldulensis, E. malliodora and E. polycarpa as a natural and herbal antimicro...

UNLABELLED PREMISE OF THE STUDY New microsatellite (simple sequence repeat [SSR]) primers were developed from Eucalyptus expressed sequence tags (ESTs) and optimized for genetic studies of the southwestern Australian tree E. gomphocephala, which is severely impacted by tree health decline and habitat fragmentation. • METHODS AND RESULTS A total of 133 gene-homologous EST-SSR primer pairs w...

The nutrient status of forest soils in the Mexico City Air Basin was evaluated by observing plant growth responses to fertilization with N, P or both nutrients combined. P deficiency was the most frequent condition for soil from two high pollution sites and N deficiency was greatest at a low N deposition site. Concentrations of Pb and Ni, and to a lesser extent Zn and Co, were higher at the hig...
