Background and Objective: Vancomycin-resistant enterococci (VRE) are the major causative agents of urinary tract infections (UTIs) in hospitalized patients. The aim of this study was to determine the prevalence of urinary tract infections caused by enterococcus faecium and the level of resistance to vancomycine and other antibiotics which are effective in enterococcal infection therapy of hospi...
A simple and specific divalent vancomycin-porphyrin has been developed. This divalent vancomycin-porphyrin conjugate indicates promising properties in fluorescent imaging and photodynamic inactivation of vancomycin-sensitive and vancomycin-resistant enterococci (VRE) bacterial strains.
background in recent decades, bacterial antibiotic resistance (especially in enterococci) has become a significant problem for human and veterinary medicine. one of the most important antibiotic resistances in enterococci, vancomycin resistance, is encoded by van gene family. objectives the aim of this study was to investigate antibiotic resistance to vancomycin in enterococci and the genes res...
infectious diseases are one of the most common causes of morbidity and mortality and the spread of resistant microorganisms is playing a significant role in this regard. the purpose of this study was to assess the trend in antimicrobial resistance of gram-positive bacteria at the main referral teaching hospital in tehran during a 4-year period. all patients' biological isolates such as blood, u...
Conditions have been optimized for the use of a multiplex PCR for the detection of vancomycin-resistant enterococci in nosocomial surveillance specimens. Seven primer sets targeting the genes vanA, vanB, vanC1, vanC2/C3 Enterococcus faecalis-specific, Enterococcus faecium-specific, and rrs (16S rRNA) were used in one reaction tube. The PCR method developed in the present study is simple and rel...
background: vancomycin (glycopeptide)-resistant enterococci (vre or gre) can cause serious problems for hospitalized patients due to the limited options for treatment of vre infections. as infection with vre increases in hospitals, further knowledge about vancomycin resistant genes is needed. methods: isolates of enterococcus spp. were collected from hospitalized patients in tehran (iran) durin...
Historically, most clinical microbiology laboratories report that 80 to 90% of enterococci are Enterococcus faecalis, whereas E. faecium accounts for 5 to 10% of isolates. At our medical center from 1993 to 2002, we evaluated the percentages of E. faecium among all enterococcal isolates and the percentages of E. faecium isolates that were vancomycin resistant. Over this 10-year period, the perc...
