Plants have been used as medicines in the treatment of diseases from the past to present. In this research, the anti-microbial effects of aqueous and methanolic extracts of Erythrostemon gilliesii were studied. For this purpose, fresh flowers were ground and then macerated in methanol 100% and water overnight. After the evaporation of solvents, anti-microbial activities of the concentrated extr...
Abstract Background: Diagnosis of bacterial causes of cutaneous infections and determination of their resistance to different antibiotics is required for choosing the optimal treatment. This study was performed on bacterial cultures which were taken from patients with cutaneous infections. Materials and methods: Samples were collected from 110 patients with cutaneous infections referred to...
Sepsis is one of the most critical medical emergency situations. Treatment with anti microbial drugs should be initiated as soon as samples of blood and other relevant sites have been cultured. Available information about patterns of anti microbial Susceptibility among bacterial isolates from the community, the hospital, and the patient should be taken in to account. It is important, pending cu...
Background : The development of microbial resistance to the existing anti-microbial agents has become a real challenge and a serious problem facing patients suffering from skin infections. Seeds of Nigella sativa have been used for a long time in folk medicine for the treatment of skin infections. Production of new potent agents is urgently needed, especially for hospitals and health care cen...
Iron, one of the essential micronutrients, is needed for electron transport and metabolic processes in almost all living organisms. The ferric form (Fe3+) of iron is insoluble in nature and inaccessible at physiological pH (7.35–7.40). Under iron-limited conditions, metal-chelating agents such as siderophores are synthesized by many bacteria and a few fungi. Siderophores have a high affinity fo...
