Resistant of pathogens to common antibiotics is a major global problem, and efforts discover new antibiotics from less known resources, is an inevitable. Native sponges of Persian Gulf have high potential in the field of medical biology, but have received little attention. In this study, actinomycetes that capable to produce anti-bacterial metabolites isolated and examined. Two sponges of Persi...
In order to study the biological control of carnation vascular wilt disease caused by Fusarium oxysporum f.sp. dianthi, 141 bacterial strains were isolated from carnation rhizosphere, and their antagonistic activity was evaluated against fungal pathogen in dual culture method. Among the tested strains, 16 strains showed antagonistic activity seven of them with more activity were selected for fu...
Petroleum refining industries produce large amounts of toxic effluents, causing environmental pollution. Iran is an oil-rich country that encounters oil pollution in its soil and water. Bioremediation of these pollutants is an appropriate solution to tackle them, compared to physical and chemical remediation methods. There are some factors that increase the rate of biodegradation; therefore, th...

Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive diseases which negatively affect the tomato production worldwide. Considering the importance of the disease, using biological control agents could be effective approaches in reducing the damage of the pathogen. Tomato samples of suspected bacterial wilt disease were gathered from different regions of East Azarbayjan....
This research investigated the feasibility of using three strains Lactobacillus sp. viz. AM11, AM13, and AM14 previously isolated from dairy products to be used as probiotics in fish diet for phytase production. The bacteria grown in oxygenated media, bile salt, acid and supernatant of digestive tract were examined for their antibiotic resistance and non-pathogenicity for using in fish feed. R...
Objective: In recent years, there has been an increasing interest in using herbal products to overcome bacterial resistance. The aim of this study was to investigate the effect of lemon verbena aqueous extract, verbascoside and caffeine in combination with gentamicin against standard and clinical isolates of Staphylococcus aureus and Escherichia coli strains. Materials and Methods: The MIC and ...
Mupirocin (MUP) is an effective antibiotic against MRSA. Its bactericidal effect stable under acid condition. By validating its antibacterial of Helicobacter pylori, we try to clarify MUP on H. pylori. The present study was conducted investigate the clarithromycin (CLR) / metronidazole (MNZ) -resistant and -susceptible strains time-kill MUP, post (PAE). We investigated minimal inhibitory concen...
Background: Populations of Magnaporthe, the causal agent of rice blast disease, are pathotypically and genetically diverse and therefore their interaction with different rice cultivars and also antagonistic microorganisms are very complicated. Objectives: The objectives of the present study were to characterize phylogenetic relationships of 114 native Magnaporthe strains, isolated from rice a...
