[ 1 ] - بررسی اثر ضدّمیکروبی عصاره اتانولی برگ چای ترش (HibiscusSabdariffa) در برابر کلبسیلا پنومونه ای مقاوم به آنتی بیوتیک‌های مختلف

زمینه و هدف: گیاه چای ترش به طور گسترده در مناطق حارّه ای کشت می شود و رنگ گلبرگ آن به عنوان نوشیدنی و رنگ غذایی کاربرد دارد. برای پیشگیری و درمان سنگ های کلیوی و مثانه در طب سنّتی، هم چنین به عنوان آنتی باکتریال، ضدّقارچ و مادّه هیپوکلسترولمیک استفاده می شود. کلبسیلا پنومونیه یک پاتوژن فرصت طلب گرم منفی و یکی از عوامل شایع عفونت های بیمارستانی است. این باکتری، به ویژه در نوزادان باعث پنومونی، سپت...

[ 2 ] - بررسی خاصیّت ضدّمیکروبی عصاره های اتانولی گیاهان آویشن، مورد و سیر بر روی تشکیل بیوفیلم استافیلوکوکوس آرئوس

زمینه و هدف: جمعیّت های متشکّل از یک گونه یا گونه های متنوّع باکتری به صورت چسبیده به یکدیگر و یا به سطوح زنده و غیر زنده در زمینه ای از پلی ساکاریدهای خارج سلولی بیوفیلم نامیده می شود. توسعه بیوفیلم یک فرآیند پیچیده است که نیازمند رفتارهای جمعی باکتری می باشد و در مقایسه با زندگی منفرد فوایسد زیادی را برای باکتری در بر دارد. بیوفیلم پراکنش باکتری و بیماری زایی باکتری را افزایش می دهد. از آن‌جایی...

[ 3 ] - Antibacterial effects of silver nanoparticlesagainst resistant strains of E.coli bacteria

The aim study antibacterial effects of silver nanoparticles against resistant strains of E.coli bacteria.12 strains of E. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. Minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. The highest MIC values was found to be 100ppm against ...

[ 4 ] - Antibacterial activity of silver Nanoparticles produced by Rosmarinus officinalis L leaf extract against some human pathogenic bacteria

The synthesis of nanoparticles from biological processes is evolving a new era of research interests in nanotechnology. The aim of this study was to determined antibacterial activity of silver nanoparticles produced by Rosmarinus officinalis L leaf extract against some human pathogenic bacteria. The formation and characterisation of AgNPs were confirmed by UV-Vis spectroscopy, energy-dispersive...

[ 5 ] - Study the Effect of Ethanol Extract of Achillea, Green Tea and Ajowan on Pseudomonas Aeruginosa

Objective: Infections are increasing caused by antibiotic-resistant Pseudomonas aeruginosa day by day. For this reason, many researchers have tried to find new compounds as alternative antibiotics. The purpose of this study was to evaluate the effect of yarrow extract, green tea and Ajowan on Pseudomonas aeruginosa. Methods: Extraction of Achillea, green tea and Ajowan was done with rotary. F...

[ 6 ] - Antimicrobial Activities of Teucrium Polium Against Salmonella Typhimurium

Objective: Teucrium polium L. (family Lamiaceae) is a wild-growing flowering plant, found abundantly in South-Western Asia, Europe and North Africa. Traditionally, T. polium has been used for different pathological conditions such as gastrointestinal disorders, inflammations, diabetes and rheumatism. The purpose of this study was to evaluate the antimicrobial effect of ethanol extract of Teucri...

[ 7 ] - Antimicrobial Impact of Hibiscus Sabdariffal Extract Against Acinetobacterbaumannii

Objective: Antibiotic resistant to Antimicrobial agent is one of the most important concern in hospitals, which can cause lots of costs, treatment fails and mortality rates. Acinetobacter baumannii is a Gram-negative bacterial pathogen notorious for causing serious nosocomial infections that resist antibiotic therapy. The purpose of current study was to define the evolution of antimicrobial imp...
