Background: Enterococci have emerged as a major cause of nosocomial infections and within this group, Enterococcus faecalis and Enterococcus faecium cause the majority of human and livestock enterococcal infections. In this article, we tried to determine antibiotics and metals resistance patterns of E. faecalis and E. faecium strains. Methods: One hundred sixty different strains of E. faecalis...
Multidrug Resistance and Virulence Factors of Enterococci Isolated from Milk and Some Dairy Desserts
Background: Enterococci spp. bacteria especially Enterococcus faecalis and E. faecium have the ability to acquire antibiotic-resistance pattern and causing life-threatening hospital-acquired infections. So, the aim of this study was to count and isolate of E. faecalis and E. faecium from milk and dairy desserts consumed in Assiut city, Egypt. Methods: A total of 100 raw milk, ice cream, mehall...
Fluoroquinolones are poorly active against enterococci. Recently, plasmid-borne resistance to fluoroquinolones due to the qnr gene was reported in members of the Enterobacteriaceae family. The gene encodes a pentapeptide repeat protein that protects DNA gyrase from inhibition by fluoroquinolones. We have identified in the genome of Enterococcus faecalis V583 a qnr-like gene, named E. faecalis q...
Abstract Background and Objective: some of predisposing factors for enterococci colonization are hospitalization in ICU, prolonged use of antibiotics and continued bed rest in hospital. In this study antibiotic resistance of enterococcus in hospitalized patients of four hospitals in Tehran were studied. Material and Methods: the Clinical samples were taken from patients admitted to the ICU, fro...
OBJECTIVE To evaluate, in vitro, the antimicrobial activity and biofilm formation of three chlorhexidine varnishes in four E. faecalis strains: E. faecalis ATCC 29212, E. faecalis EF-D1 (from failed endodontic treatment), E. faecalis 072 (cheese) and E. faecalis U-1765 (nosocomial infection), and one E. durans strain (failed endodontic treatment). STUDY DESIGN The direct contact test was used...
Although much is known about vancomycin-resistant (VR) Enterococcus faecium, little is known about the epidemiology of VR Enterococcus faecalis. The predilection of VR E. faecalis to transfer the vancomycin resistance determinant to Staphylococcus aureus is much greater than that of VR E. faecium. The epidemiology of VR E. faecalis has important implications regarding the emergence of vancomyci...
Background: During the last decade, enterococci have become important nosocomial pathogens, representing the second leading cause of urinary tract infections. This increasing prevalence has been paralleled by the occurrence of multi-drug resistant (MDR) and high-level gentamicin resistant (HLGR) strains. Methods: From September 2005 to 2006, a total of 638 enterococcal isolates were collected ...
Background and Aim: Because of complexity in root canals, irrigating solutions are needed in addition to mechanical instrumentation for thorough cleansing of the root canal system. This in-vitro study was designed to determine the inhibitory effect of arginine, protamine, and aqueous extracts of green tea and aloe vera against Enterococcus faecalis (E. faecalis), which causes endodontic failure...
The present study aimed to evaluate the effects of Enterococcus faecalis, inactivated by the common intracanal irrigants sodium hypochlorite (NaOCl) and chlorhexidine (CHX), on osteoblasts. E. faecalis was inactivated with 2% CHX or 5.25% NaOCl. Subsequently, the Cell Counting kit‑8 assay was used to examine the effects of CHX‑ and NaOCl-inactivated E. faecalis on MC3T3‑E1 osteoblast cell proli...
background: the aim of this study was to determine the occurrence of virulence determinants and vancomycin- resistant genes among enterococcus faecalis and e. faecium obtained from various clinical sources. methods: the study was performed on the 280 enterococcal isolated from clinical specimens in hamadan hospitals, western iran in 2012-14. antibiotic susceptibility testing was performed using...
