Prevalence of Enterococcus Species in Various Clinical Samples and Their Antimicrobial Susceptibility Pattern.
Cureus
November 2024
Department of Microbiology, Krishna Vishwa Vidyapeeth (Deemed to be University), Karad, IND.
Article Synopsis
- Gram-positive enterococci, normally harmless gut bacteria, have become significant health threats, particularly to immunocompromised individuals, due to their ability to resist multiple antibiotics.
- An observational study involving 114 clinical samples (like urine and blood) aimed to assess the prevalence and resistance patterns of enterococci, highlighting a critical need for better infection control and surveillance measures.
- Results indicated that most isolates originated from urine (69.16%), with the highest infection rates found in individuals aged 41 to 50, emphasizing the varied distribution of these pathogens in clinical settings.
Genome analysis of multidrug resistant Enterococcus faecium and Enterococcus faecalis circulating among hospitalized patients in uMgungundlovu District, KwaZulu-Natal, South Africa.

Antimicrobial Research Unit, School of Health Sciences, University of KwaZulu-Natal, Durban, 4000, South Africa.
Background: Vancomycin-resistant enterococci (VRE) are important pathogens categorized as high-priority bacteria in the Global Priority List of Antibiotic-Resistant Bacteria to Guide Research, Discovery, and Development of New Antibiotics published by the World Health Organization. The aim of this study was to determine the risk factors, resistance, virulence, mobilomes associated with multidrug-resistant and clonal lineages of Enterococcus faecium and faecalis circulating among hospitalized patients following the health system in South Africa, using whole genome sequencing (WGS).
Methods: A cross-sectional study was conducted during a two-month periods among hospitalized patients in 2017.
Fully Characterized Effective Bacteriophages Specific against Antibiotic-Resistant , the Causative Agent of Dental Abscess.
Medicina (Kaunas)
March 2024
Botany and Microbiology Department, Faculty of Science, Al-Azhar University, Nasr, Cairo 11884, Egypt.
: is a primary pathogen responsible for dental abscesses, which cause inflammation and pain when trapped between the crown and soft tissues of an erupted tooth. Therefore, this study aims to use specific phages as an alternative method instead of classical treatments based on antibiotics to destroy multidrug-resistant bacteria for treating dental issues. : In the current study, twenty-five bacterial isolates were obtained from infected dental specimens; only five had the ability to grow on bile esculin agar, and among these five, only two were described to be extensive multidrug-resistant isolates.

BMC Infect Dis
March 2024
Molecular and Cell Biology Research Centre, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran.
Background: Currently, antibiotic-resistant strains of Enterococcus are considered to be one of the critical health challenges globally. This study aimed to investigate the antibiotic susceptibility pattern, biofilm formation capacity, and virulence genes of enterococci isolated from different sources.
Methods: In this cross-sectional study, environmental and fecal samples were collected from the hospital environment, volunteers, and hospital staff from October 2018 to August 2019.
Antimicrobial resistance and whole genome sequencing of novel sequence types of Enterococcus faecalis, Enterococcus faecium, and Enterococcus durans isolated from livestock.
Sci Rep

Department of Veterinary Science, Martin-Gatton College of Agriculture, Food, and Environment, University of Kentucky, Lexington, KY, 40546, USA.
The emergence of antimicrobial-resistant, livestock-associated Enterococcus faecalis represents a public health concern. Here, we report the isolation, molecular detection of virulence and antimicrobial resistance determinants, in addition to the phylogenetic analyses of 20 Enterococcus species using whole genome sequencing analysis of 15 Enterococcus faecalis strains including six strains of three novel sequence types, three Enterococcus faecium and two Enterococcus durans. All strains were isolated from food chain animals in South Africa.
