Abstract Background and Objective: Antibiotics are the chemical compounds, which are produced by microorganisms, belong to a larger group of antimicrobial compounds that are used for treatment of infections caused by microorganisms. Material and Methods: the isolates of four plant species, ...
Background & Aims: Nocardia are gram-positive, aerobic, relative acid-fast, and opportunistic bacteria, and one of the causes of systematic infection around the world. The natural habitats of these bacteria are soil and dust. Hospitalized patients with immune deficiency are at high risk of transmission of opportunistic infection. Due to these facts and...
background: glyphosate (n-phosphonomethyl glycine) is an organophosphorus pesticide with dangerous effects on the environment. in this study, the biodegradation of glyphosate herbicide by halophilic bacteria isolated from qom hoze-soltan lake has been investigated. methods: after sampling and bacterial isolation, native halophilic strains grown in the presence of glyphosate at a wavelength of 6...
Rapid and in time diagnosis of phenylketonuria (PKU) in affected infants can help preventing the progress of mental and developmental disorders associated with the disease. Here we report the isolation of alkaliphilic Bacillus bacteria capable of producing high level of Phenylalanine dehydrogenase (PheDH) from soil. A new quantitative and rapid test for PKU diagnosis was then developed using th...
This study was conducted to evaluate the resistance to antibiotics in the western white shrimp propagation centers on pathogens of Vibrio bacteria. In Iran, the most important bacteria in the shrimp are the vibrio species. In Bushehr Province, due to the high efficacy of erythromycin antibiotics, streptomycyne oxytracycline and tremitoprim in bacterial diseases, were selected as the species. Th...
there is a long period between harvested beets and their transfer to the sugar factory. sugar beet crop is damaged and injured during harvest and transport which provides a suitable place for various saccharoliytic microorganisms growth in terms of temperature, moisture, ph and glucose concentration. in this study, samples were randomly selected from the roots stored in spring 2010 and also the...
community-acquired pneumonia and brucellosis are of the main agents causing mortality in the world. the most important limitations for the identification of these agents include their high resistance against environmental conditions, impossibility of rapid and on time diagnosis, low level of infective dose, and lack of existence of vaccine against many types of them. hence, on time action and d...
Background: Glyphosate (N-phosphonomethyl Glycine) is an organophosphorus pesticide with dangerous effects on the environment. In this study, the biodegradation of glyphosate herbicide by halophilic bacteria isolated from Qom Hoze-Soltan Lake has been investigated. Methods: After sampling and bacterial isolation, native halophilic strains grown in the presence of glyphosate at a wavelength of 6...
