Enterococci have controversial status due to their emerging role in nosocomial infections and transmission of antibiotic resistance genes, while some enterococci strains are used as probiotics for humans and animals and starter cultures in dairy industry. In order to improve our understanding of factors involved in the safe use of enterococci as potential probiotics, the antibiotic susceptibili...

BACKGROUND Enterococci are important pathogens in nosocomial infections. Various types of antibiotics, such as aminoglycosides, are used for treatment of these infections. Enterococci can acquire resistant traits, which can lead to therapeutic problems with aminoglycosides. OBJECTIVES This study was designed to identify the prevalence of, and to compare, the aac(6')-aph(2") and aph(3)-IIIa ge...

INTRODUCTION In the past two decades members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. This study prospectively analyzed the distribution of species and trends in antimicrobial resistance among clinical isolates of enterococci in a Brazilian tertiary hospital from 2006-2009. METHODS Enterococcal species were identified by conventional biochemical test...

Abstract. Hayati Z, Desfiana UH, Suhartono S. 2022. Distribution of multidrug-resistant Enterococcus faecalis and faecium isolated from clinical specimens in the Zainoel Abidin General Hospital, Banda Aceh, Indonesia. Biodiversitas 23: 5043-5049. are two predominant enterococcal species associated with opportunistic infections, especially settings. This study aimed to determine distribution ant...

In the USA, vancomycin-resistant Enterococcus faecium (VREF) is endemic in hospitals, despite lack of carriage among healthy individuals. In Europe, however, hospital outbreaks are rare, but VREF carriage among healthy individuals and livestock is common. We used amplified fragment-length polymorphism analysis to genotype 120 VREF isolates associated with hospital outbreaks and 45 non-epidemic ...

The toxin-antitoxin (TA) system is a regulatory system where two sets of genes encode the toxin and its corresponding antitoxin. In this study, the prevalence of TA systems in independently isolated clinical isolates of Enterococcus faecium and Enterococcus faecalis was determined, the dominant TA system was identified, different virulence genes in E. faecium and E. faecalis were surveyed, the ...

Objective: Fosfomycin is an alternative drug for treatment of uncomplicated urinary tract infections. This study aimed to investigate in vitro activity of fosfomycin against methicillin-resistant Staphylococcus aureus (MRSA), methicillinresistant coagulase negative staphylococci (MRCoNS), vancomycin-resistant Enterococcus faecium (VR E. faecium), Escherichia coli, Klebsiella pneumoniae, and Ent...

We collected 103 clinical Enterococcus faecium isolates from across Canada, performed standard broth microdilution susceptibility testing, and compared these results with results from the MicroScan Pos MIC Type 6 panel (Baxter Health Care Corp., West Sacramento, Calif.) and the AMS-Vitek Gram-Positive Susceptibility card (Vitek Inc., St. Louis, Mo.). High-level aminoglycoside resistance to gent...

background enterococcus faecium is an important nosocomial pathogen and has developed resistance to multiple antibiotics, such as vancomycin. nitrofurantoin is active against e. faecium and e. faecalis, including vana- and vanb-positive isolates. objectives to investigate the role of rpob mutation in e. faecium. methods the growth rate and reactive oxygen species (ros) levels were determined. t...

The enterococcal community from feces of seven dogs treated with antibiotics for 2-9 days in the veterinary intensive care unit (ICU) was characterized. Both, culture-based approach and culture-independent 16S rDNA amplicon 454 pyrosequencing, revealed an abnormally large enterococcal community: 1.4±0.8×10(8) CFU gram(-1) of feces and 48.9±11.5% of the total 16,228 sequences, respectively. The ...
