Examining Antimicrobial Resistance in Enterococcus Species: A Single-Center Cross-Sectional Study

Background: Antimicrobial resistance in Enterococcus species is a growing global concern. These bacteria, commonly found in the human gut, have resisted multiple antibiotics, making infections harder to treat. This poses a significant challenge for healthcare as it limits treatment options and highlights the urgent need for responsible antibiotic use and the development of new therapies. Aim of the study: The study aimed to determine the antimicrobial resistance pattern of Enterococcus Species at a tertiary care hospital in Bangladesh. Methods: This cross-sectional research occurred at Sample collected from deferent laboratories situated in rangpur and test/research perform, Department of Microbiology in prime institute of science and medical technology (PRISMET), Rangpur During March’ 2022 to March’ 2023. It spanned one year from [start date] to [end date]. The primary goal was to evaluate the antimicrobial susceptibility patterns of enterococci. Throughout the study, 1,450 samples were collected from various sources, including urine, blood, pus, swabs, and fluids. However, only 62 Enterococci isolates were successfully obtained. Standard microbiological protocols, such as microscopy and culture, were rigorously followed during sample processing. All clinical samples received at the Microbiology laboratory during the study were considered for inclusion. Data analysis was conducted using Microsoft Excel and presented with tables and graphs, while SPSS was employed for statistical analysis. Result: The study population primarily consisted of patients aged 36-75 (77.42%), averaging 52.01 years. Gender distribution was skewed towards males (59.68%). Enterococcus spp. They have dominated the microbial species (64.52%), with E. faecalis (14.52%) and E. faecium (11.29%) being prevalent. Urine samples were the most common (66.13%), followed by pus (11.29%) and swab (9.68%). Antibiotic susceptibility analysis showed varying results, with amoxicillin being sensitive in 87.10% of cases, while Cefixime, Ceftazidime, Ceftriaxone, and Cefotaxime exhibited over 96% resistance. Conclusion: This study highlights the rise of antimicrobial resistance (AMR) in Enterococcus species at a Bangladeshi tertiary care hospital. Once harmless, these bacteria now pose a severe risk to public health. Our research shows that E. faecalis and E. faecium have become resistant to many common antibiotics, particularly cephalosporins, urging immediate antibiotic stewardship and infection control. To combat this global health threat, we must explore novel treatments and employ a multidisciplinary approach to protect patients and healthcare systems from Enterococcus infections.
