Determination of antibiotic susceptibility and Minimum Inhibitory Concentration (MIC) of the Propionibacterium acnes to the prevalent antibiotics in the treatment of Acne vulgaris
ABSTRACTPropionibacterium acnes is propounded as one of the significant factors in occurrence of acne. Today, due to development of the antibiotic resistance, most of the acne treatments are faced with failure. In order to determine the antibiotic resistance of the P.acnes strains isolated from the patients with acne, this research has been carried out. 70 samples collected using microbial cult...
متن کاملبررسی اثر ضد میکروبی عصاره‌ی اتانولی برگ درخت گردو بر روی پروپیونی باکتریوم آکنه
Background and Objective: Acne is one of the medical problems and propionibacterium acnes is the pathogenic agent that has received a considerable attention. Different parts of Juglans regia have been shown to have antibacterial activity on many bacteria. Its leaves have antioxidant property and if it shows antibacterial effect on propionibacterium acnes, it might be an alternative drug for the...
متن کاملIsolation and Characterization of a New Thermoalkalophilic Lipase from Soil Bacteria
Lipases are diversified enzymes in their properties and substrate specificity, which make them attractive tools for various industrial applications. In this study, an alkaline thermostable lipase producing bacteria were isolated from soil of different regions of Isfahan province (Iran) and its lipase was purified by ammonium sulfate precipitation and ion exchange chromatography. To select a the...
متن کاملMolecular Cloning and Characterization of a Lipase from an Indigenous Bacillus pumilus
Cloning and sequencing of a lipase gene from an indigenous Bacillus pumilus, strain F3, revealed an open-reading frame of 648 nucleotides predicted to encode a protein of 215 residues. Sequence analysis showed that F3 lipase contained a signal peptide composed of 34 amino acids with an H domain of 18 residues. A tat-like motif was found in the signal peptide similar to some other Bacillus pumil...
