Introduction: Using zinc oxide nanoparticles, as a catalyst removal of fecal pollution indicator bacteria in water, has been studied as a model of bacterial contamination. This study aims to determine the toxicity and selection of appropriate indicators to evaluate the toxicity of zinc oxide nanoparticles on the isolated bacteria Vibrio species of Bushehr coastal waters. Methods: In this experi...
باکتریهای لومینسانس در انواع مختلفی از محیط های طبیعی یافت می شود. این باکتریها اهمیت ویژه ای از جنبه های اکولوژیکی و بیوتکنولوژی دارند. در این مطالعه سعی گردید تا حضور یا عدم حضور باکتریهای لومینسانس در حوضچه های طبیعی پرورش میگو که با آب خیلج فارس مرتبط هستند مورد بررسی قرار گرفته و خصوصیات مختلف مورفولوژیکی و بیوشیمیایی آنها مورد بررسی قرار گیرد. علاوه بر روشهای متداول میکروبیولوژیکی از ژن 1...
Vibrio species are the major seafood-borne bacteria that are frequently associated with the consumption of contaminated sea food. A total of 113 samples including 58 fish and 55 shrimps were studied for the possible contamination with Vibrio species. A biochemical protocol was applied for the identification of the Vibrio isolates and Polymerase Chain Reaction (PCR) was carried out to confirm th...
در این تحقیق اثرات ضدباکتریایی اسانس¬های 4 گیاه دارویی زنیان (carum copticum)، شوید (anethum graveolens)، رازیانه (foeniculum vulgare) و نعناع فلفلی (mentha piperita)، بر سه باکتری بیماری¬زا (vibrio parahaemolyticus، vibrio harveyi و vibrio damsela) مورد بررسی قرار گرفت. برای تعیین حداقل غلظت بازدارندگی (mic)از روش استاندارد میکرودایلوشن (broth microdilution) استفاده شد و حداقل غلظت باکتری¬کشی ...
quick identification of vibrio cholerae in epidemics is important, on the other hand; conventional methods are time-consuming and costly. the aim of this study was to develop a rapid, inexpensive and high sensitivity method for quick identification of vibrio cholerae . for this purpose we designed a pcr detection based on magnetic nanoparticles for identification of bacterial dna by p...

مقدمه: باکتریهای گرم منفی از مهمترین باکتریهای بیماریزا برای موجودات دریایی از جمله ماهیان زینتی هستند. مواد و روشها: در این پژوهش گونههای vibrio از ماهی زینتی گوپی در استخرهای پرورش ماهی کاشان، اصفهان، ایران جداسازی و بر اساس روشهای تشخیص مولکولی و توالی یابی ژنتیکی شناسایی شدند. نمونههای کبد، کلیه، پوست، مغز و آبشش از ماهی زینتی گوپی در منطقه کاشان، اصفهان، ایران در مراحل لارو، بالغ ...
The aim of this research was to study the occurrence of Vibrio spp., Aeromonas hydrophila, Escherichia coli and Campylobacter spp. in crayfish from Azerbaijan Province using culture method and PCR assay. A total of 55 isolates were collected from 97 studied samples. Vibrio spp., A. hydrophila, E. coli and Campylobacter spp. were detected in 26 samples (26.8%), 12 samples (12.3%), 15 samples (15...
