The total synthesis of two key analogues of vancomycin containing single-atom exchanges in the binding pocket (residue 4 amidine and thioamide) are disclosed as well as their peripherally modified (4-chlorobiphenyl)methyl (CBP) derivatives. Their assessment indicates that combined pocket amidine and CBP peripherally modified analogues exhibit a remarkable spectrum of antimicrobial activity (VSS...
INTRODUCTION Laboratory-based surveillance is an important component in the control of vancomycin resistant enterococci (VRE). METHODS The study aimed to evaluate real-time polymerase chain reaction (RT-PCR) (genes vanA-vanB) for VRE detection on 115 swabs from patients included in a surveillance program. RESULTS Sensitivity of RT-PCR was similar to primary culture (75% and 79.5%, respectiv...
The complete genome sequence of Enterococcus faecalis V583, a vancomycin-resistant clinical isolate, revealed that more than a quarter of the genome consists of probable mobile or foreign DNA. One of the predicted mobile elements is a previously unknown vanB vancomycin-resistance conjugative transposon. Three plasmids were identified, including two pheromone-sensing conjugative plasmids, one en...
Türkiye’de Van ili piyasasından toplanan tavuk eti örneklerinde Enterococcus spp. prevelansı ve antibiyotik direnliliği VanA VanB direnç genlerinin belirlenmesi amaçlandı. Çalışmada 100 adet örneği kullanıldı. Bunların 27’si (%27) pozitif bulundu. 27 örneğinden toplam 67 izolatı elde edildi. Bunlardan 53’ü (%79.10) E. faecalis, 14’ü (%20.90) ise faecium olarak tespit Antibiyotik dirençlilikleri...
Background & Objectives: Isolation of vancomycin resistant Enterococcus from clinical samples is very important. The aim of this study was evaluation of phenotype and genotype of van genes in vancomycine resistant Enterococcus. Materials and Methods: 411 Enterococcus isolates were collected from selected Tehran’s hospitals between March 2004 and December 2007. The enterococcal isolates were ide...
The aim of the study was to assess the epidemiology, the incidence of multidrug-resistant bacteria and bloodstream infections' (BSIs) seasonality in a university hospital. This retrospective study was carried out in the University General Hospital of Patras, Greece, during 2011-13 y. Blood cultures from patients with clinical presentation suggestive of bloodstream infection were performed by th...
Surveillance for Vancomycin Resistant Enterococci in a Tertiary Institution in South Western Nigeria
BACKGROUND Enterococci are responsible for up to 12% of cases of healthcare associated infections worldwide and cause life threatening infections among critically ill patients. They show intrinsic and acquired resistance to a wide range of antimicrobial agents. Glycopeptide resistance is due to vanA, vanB, vanC, vanD, vanE, vanG and vanL genes. OBJECTIVES To determine the carriage rate of VRE...
