INTRODUCTION The present study evaluated biofilm-forming capacity and the presence of both icaA and icaD genes among staphylococcal strains isolated from catheter-related infections and blood culture. METHODOLOGY Ninety staphylococcal isolates, which included 45 strains of catheter infection origin and 45 strains of blood culture origin, were tested for their ability to produce biofilm using ...
BACKGROUND Symptomatic intracranial atherosclerotic disease (ICAD) worldwide represents one of the most prevalent causes of stroke. When severe, studies show that it has a very high risk for recurrent stroke, highlighting the need for effective preventative strategies. The mainstay of treatment has been medical therapy and is of critical importance in all patients with this disease. Endovascula...
OBJECTIVES We aimed to characterise the staphylococcal cassette chromosome mec (SCCmec) type, genetic relatedness, biofilm formation and composition, icaADBC genes detection, icaD expression, and antibiotic susceptibility of planktonic and biofilm cells of Staphylococcus hominis isolates from blood. METHODS The study included 67 S. hominis blood isolates. Methicillin resistance was evaluated ...
BACKGROUND AND PURPOSE ICAD with hemodynamic insufficiency may present with either fulminant infarct or with progressive neurologic deterioration. The purpose of this study was to evaluate the safety and efficacy of emergent self-expanding stent placement for acute intracranial or extracranial ICAD with significant hemodynamic insufficiency. MATERIALS AND METHODS Eight patients (7 men and 1 w...
BACKGROUND AND PURPOSE Although studies have attempted to differentiate intracranial vascular disease using vessel wall magnetic resonance imaging (VWI), none have incorporated multicontrast imaging. This study uses T1- and T2-weighted VWI to differentiate intracranial vasculopathies. METHODS We retrospectively reviewed patients with clinically defined intracranial vasculopathies causing lumi...
Biofilm-forming ability is increasingly being recognized as an important virulence factor in several Staphylococcus species. This study evaluated the biofilm-forming ability of sixty canine derived clinical isolates of S. pseudintermedius, using three phenotypic methods, microtiter plate test (MtP), Congo red agar method (CRA) and tube adherence test, and the presence and impact of biofilm-asso...
BACKGROUND AND PURPOSE Cervical artery dissection (CAD) accounts for 10-20% of ischemic strokes in young adults. Although trauma and preexisting disorders of the arterial wall are the main predisposing factors, most CADs are considered 'spontaneous'. We hypothesized that CAD could originate in systemic vascular disease bound to the intima-media interface without clinical signs. If this hypothes...
مقدمه: استافیلوکوکوس اورئوس یکی از عوامل اصلی عفونتهای بیمارستانی بوده و به دلیل تشکیل بیوفیلم طیف وسیعی از بیماری ها را ایجاد می کند. این مطالعه با هدف بررسی ترکیبات شیمیایی عصاره گیاه گل بیمرگ، اثرات ضدبیوفیلمی آن بر روی جدایههای بالینی استافیلوکوکوس اورئوس مقاوم به متی سیلین و آنالیز بیان ژن icaD انجام شد. مواد و روش ها: ابتدا ترکیبات فیتوشیمیایی عصاره گیاه گل بی مرگ با استفاده از روش G...
سابقه و هدف: شیوع سویه های استافیلوکوکوس اورئوس مقاوم به متیسیلین یکی از مهمترین مشکلات بهداشتی و تهدید کنندۀ سلامت در سراسر دنیا است. این سویهها با توانایی تشکیل بیوفیلم و اسلایم، قابلیت کلونیزاسیون و انتقال بیشتری را دارند. مطالعۀ حاضر بمنظور بررسی حضور ژنهای icaA و icaD و تشکیل بیوفیلم و اسلایم در ایزولههای بالینی استافیلوکوکوس اورئوس مقاوم به متیسیلین حامل ژن mecA انجام گرفت. مواد و...
