The stimulating effect of subinhibitory concentrations of antibiotics on the production of verocytotoxin (VT) by enterohaemorrhagic Escherichia coli (EHEC) O157:H7 has been claimed. The purpose of this study was to find an alternative, but bioactive medicine for the treatment of this organism. Fifty-eight preparations of aqueous and ethanolic extracts of 38 medicinal plant species commonly used...
Background and purpose: Dental caries is a pathological infectious disease. It begins with the formation of dental plaques which is a structurally and functionally organized biofilm. Streptococcus mutans is the most important bacterium in the formation of dental plaque and dental caries. This study aimed at evaluating the antibacterial and antibiofilm activity of Quercus infectoria galls agains...
BACKGROUND Galls of Quercus infectoria have been traditionally used to treat common ailments, including yeast infections caused by Candida species. OBJECTIVE This study aimed to evaluate the in vitro anti-Candida activity of Q. infectoria gall extracts against selected Candida species. MATERIALS AND METHODS Methanol and aqueous extracts of Q. infectoria galls were tested for anti-Candida ac...
این پژوهش به منظور بررسی تأثیر برخی ویژگی های فیزیکی و شیمیایی خاک بر مشخصات کمی دارمازو (quercus infectoria) انجام شد. 36 قطعه نمونه دایرهای شکل به مساحت 10 آر به صورت تصادفی در فرم های مختلف زمین در منطقه مورد مطالعه انتخاب و مشخصه های کمی ازقبیل تعداد، ارتفاع، قطر برابر سینه و قطر تاج درختان در داخل هر یک از قطعات نمونه اندازه گیری شد و در قالب طرح کامل تصادفی با 12 تیمار و سه تکرار برداشت...
جوانهخوار بلوط (Tortrix viridana L.) مهمترین آفت بلوط در ایران است. جهت بررسی تغییرات جمعیتی این آفت نمونهبرداریهای هفتگی از مراحل مختلف زندگی این آفت در آذربایجانغربی صورت گرفت. تعداد سنین لاروی با پرورش و اندازهگیری عرض کپسول سر 1000 عدد لارو سنین مختلف تعیین شد. تأثیر میزبان گیاهی بر تغییرات وزنی لاروهای سن آخر و شفیره آفت روی سه گونه بلوط (Quercus infectoria، Q. brantii و Q. libani) ب...
Background: Quercus infectoria gall (Oak) has a long history of use as a medicinal plant. Andricus moreae galls arise on young branches of Quercus infectoria as a result of attack by bees.In this research, the antibacterial activity of methanol and acetone extracts of gall (Quercus infectoria) against Staphylococcus aureus, Bacillus cereus, B.subtilis strains was evaluated. Material and met...
The present study indicates the efficacy of extracts and fractions of Quercus lusitania var. infectoria galls (Oliv.) as larvicidal agents and their possible use in biological control of Culex pipiens, the urban nuisance mosquito. Extracts and fractions were tested against second and fourth instar larvae. The LC(50) values of gallotannins were 335 and 373 ppm, respectively for the 2nd and 4th i...
The present study aimed at evaluating the antibacterial activity of methanol extract of Ruta chalapensis, L., (Rutaceae), Quercus infectoria Oliver., (Fagaceae) and Canthium parviflorum Lam., (Rubiaceae) against Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Klebsiella oxytocoa, Klebsiella pneumoniae and Proteus mirabilis. The experiment was carried out using disc diffusi...
In the present study, free radical scavenging activities of the two plants, Oroxylum indicum (L) Kurz and Quercus infectoria G. Olivier were investigated. Free radical scavenging activities of stem bark of O. indicum and insect galls of Q. infectoria were characterized by the HPLC method developed by D. Chandrashekhar, et al, 2005 using Waters 100 RP-18e column (250 mm × 4 mm, 5 μM) in which st...
