Background and Aim: Enterococcus species are opportunistic pathogens and their pathogenicity seems to be related to the presence of a number of pathogenicity genes. Since donkey’s milk is a new non-allergenic source of nutrition, this study was performed to assess the antibiogram and detection of pathogenicity genes in some Enterococcus faecalis isolates from donkey’s milk. Materials and Method...
Enterococci are important because of their role as the leading cause of nosocomial infections which have a significant role in the dissemination and persistence of antimicrobial resistance genes. Methods: In this study, we determined the distribution of enterococcal species in the sewage treatment plants in Iran. Furthermore, we improved a rapid and specific PCR method using primers (sodA and ...
Enterococci are Gram-positive bacteria that are found in plants, soil and as commensals of the gastrointestinal tract of humans, mammals, and insects. Despite their commensal nature, they have also become globally important nosocomial pathogens. Within the genus Enterococcus, Enterococcus faecium, and Enterococcus faecalis are clinically most relevant. In this review, we will discuss how E. fae...
یکی از روشهای بالا بردن سطح ایمنی و سلامت ماهیان استفاده از مکملهای غذایی از جمله پروبیوتیکها میباشد. این تحقیق با هدف کاربرد باکتری انتروکوکوس فیکالیس در تغذیه و تاثیر آن روی فاکتورهای بیوشیمیایی و خونی بچه تاسماهیان ایرانی در موسسه تحقیقات بین المللی تاسماهیان دریای خزر طی سالهای 1393- 1389 انجام گرفت. تعداد 96 عدد بچه تاسماهی ایرانی با متوسط وزن (g14/0±24/9) و میانگین طول کل (cm4/...
Sir, Vancomycin-resistant enterococci constitute an increasing clinical problem in the USA, and clonal dissemination of vancomycin-resistant isolates among hospitals, especially Enterococcus faecium, has been described. In Europe, detection of vanA enterococci in the clinical setting is less frequently reported and few reports exist of clonal dissemination of resistant isolates among different ...
Aim: the aim of the present ExVivo study was to check the antimicrobial efficacy of silver nanoparticles with and without different antimicrobials against E. faecalis. Material and Methods: 126 recently extracted single rooted human teeth were contaminated with E. faecalis. The teeth were randomly divided into 5 experimental (n=21) and 1 control group (n=21). Each subgroup was then exposed to d...
The E test and the reference agar dilution methods were compared for detecting high-level aminoglycoside resistance (HLAR) among 71 selected clinical isolates, including 62 Enterococcus faecalis and 9 Enterococcus faecium isolates. High-level gentamicin resistance alone was found in 11% (5 E. faecalis and 3 E. faecium strains) and high-level streptomycin resistance was found in 42% (28 E. faeca...
background: the aim of this ex vivo study was to compare the antimicrobial effect of triantibiotic paste, 0.2% chlorhexidine gel, propolis and aloe vera on enterococcus faecalis in deep dentin. materials and methods: ninety fresh extracted single-rooted teeth were used in a dentin block model. seventy-fi ve teeth were infected with e. faecalis and divided into four experimental groups (n = 15)....
BACKGROUND Enterococcus faecalis plays a dual role in human ecology, predominantly existing as a commensal in the alimentary canal, but also as an opportunistic pathogen that frequently causes nosocomial infections like bacteremia. A number of virulence factors that contribute to the pathogenic potential of E. faecalis have been established. However, the process in which E. faecalis gains acces...
UNLABELLED Enoyl-acyl carrier protein (enoyl-ACP) reductase catalyzes the last step of the elongation cycle in the synthesis of bacterial fatty acids. The Enterococcus faecalis genome contains two genes annotated as enoyl-ACP reductases, a FabI-type enoyl-ACP reductase and a FabK-type enoyl-ACP reductase. We report that expression of either of the two proteins restores growth of an Escherichia ...
