Vancomycin-resistant enterococci strains (VRE) is an important pathogen related with hospital infections in many countries, presenting limited or no therapeutic options for treating serious infections. VRE has presented some different genotypes been VanA and VanB considered to be the most important in hospital environments. In the present study the authors investigated the prevalence of van gen...
سابقه و هدف: انتروکوک ها نقش مهمی در ایجاد اندوکاردیت و عفونت های ادراری دارند و به واسطه توانایی که در کسب مقاومت نسبت به عوامل ضد میکروبی دارند، درمان آن ها را با سختی مواجه می سازد. این مطالعه با هدف بررسی الگوی مقاومت آنتی بیوتیکی و تعیین سویه های مقاوم به ونکومایسین و هم چنین شناسایی ژن های مقاومت vanb و vana در میان ایزوله های انتروکوکوس جدا شده از بیمارستان های آموزشی درمانی شهرکرد درسال...
Hospital-acquired infections caused by vancomycin-resistant enterococci (VRE) are increasing. The resistance of VRE to multiple antibiotics makes them clinically challenging. There are at least six phenotypes of VRE, including VanA, VanB, VanC, VanD, VanE, and VanG (2, 8). These phenotypes correspond with the genotypes vanA, vanB, vanC, vanD, vanE, and vanG. VanA and VanB phenotypes are common ...
Low-level vancomycin resistance was observed for 28 clinical Clostridium innocuum isolates and C. innocuum NCIB 10674, whereas teicoplanin was active. DNA from three clinical isolates and the type strain could not be amplified by PCR with primers specific for the genes vanA, vanB, and vanC, suggesting that C. innocuum is intrinsically resistant to vancomycin.
We examined cloacal samples from poultry raised on nonintensive production farms in Brazil for the presence of vancomycin-resistant enterococci. No VanA- or VanB-containing enterococci were identified in a total of 200 cloacal swabs. The most prevalent species were Enterococcus gallinarum (vanC1; 13.0%) and E. casseliflavus (vanC2/3; 5.5%).
The main goal of the study was to analyse the occurrence of antibiotic-resistant bacterial strains in poultry in the Czech Republic in 1999–2000. The resistance was determined in 128 selected Escherichia coli, 88 Staphylococcus sp. and 228 Enterococcus sp. strains. The bacterial species were selected to represent gramnegatives and grampositives, the common part of intestinal microflora and also...
Surveillance cultures for vancomycin-resistant enterococci (VRE) and subsequent characterization of the isolates can be extremely burdensome and difficult. Therefore, efficient and reliable schemes for the characterization of surveillance isolates are needed. In this study, a commercial agar (bile esculin azide agar with 6 microg of vancomycin per ml [BEAA]; Remel, Lenexa, Kans.) was used in th...
INTRODUCTION Enterococcus spp. is considered as important etiological agents of nosocomial infections. However, a little is known about the epidemiology of vancomycin resistant Enterococcus faecalis (VREF). The aim of this study was to investigate the frequency of VREF and detecting of two prevalent resistance genes (vanA, vanB) at Children Medical Center Hospital, an Iranian referral pediatric...
چکیده زمینه و هدف : پروتئین لاکتوفرین(Lactoferrin(LF)) دارای اثرات ضدمیکروبی اثبات شده ای است. هدف از این مطالعه بررسی تأثیر لاکتوفرین روی حداقل غلظت مهاری) Minimum inhibitory concentration (MIC))وانکومایسین در سویه های انتروکوک مقاوم به وانکومایسین دارای ژنهای مقاومت VanA و VanB بود. ﻣﻮﺍﺩ ﻭ ﺭﻭﺵﻫﺎ: در این مطالعه مقطعی ، پس از جداسازی و تشخیص265 سویه انتروکوک از نمونه های بالینی ، MIC وانکومایسی...
