Prevalence of Enterococcus Species in Various Clinical Samples and Their Antimicrobial Susceptibility Pattern

Background and aim Gram-positive enterococci, which are normally prevalent in the intestine as commensals, have become important pathogens that cause serious illnesses such as meningitis, bacteremia, and endocarditis, especially in people with impaired immune systems. Due to the presence of resistance genes such as van A, B, and C, which lead to multidrug resistance, the two prevalent species, Enterococcus faecalis and Enterococcus faecium, are causing increasing concerns. In order to effectively combat these dangerous infections, there is an urgent need for improved surveillance, infection control measures, and antimicrobial stewardship. Research on the genetic features of enterococci is still lacking in India. The purpose of this work is to assess the frequency of Enterococcus isolates from different clinical samples and to examine the patterns of antibiotic resistance in these isolates. Materials and methods The purpose of this cross-sectional observational study was to assess the prevalence of Enterococcus isolates from various clinical specimens. Based on information from previous studies, a sample size of 114 was chosen. Urine, blood, sputum, wound swabs, and sterile body fluids were all used for the isolation of bacteria. Through the use of biochemical tests such as bile esculin hydrolysis and salt tolerance, gram staining, and cultural traits, enterococci were identified. The Kirby-Bauer disc diffusion method was utilized to evaluate antibiotic susceptibility, with a specific focus on resistance patterns. The findings show that in order to address the increasing problems that these pathogens are posing in hospital settings, there is an urgent need for improved surveillance and efficient infection control strategies. Results The results of the investigation showed that different clinical specimens had different distributions of Enterococcus species. The majority of isolates (69.16%) came from urine samples, with blood samples making up the remaining 12.5%. The age group between 41 and 50 years old had the highest occurrence, with a notable male predominance. The majority of Enterococcus isolates (96.66%) came from inpatient settings, specifically from the critical care units (CCU) and intensive care units (ICU). Teicoplanin sensitivity was highest among the isolates (79.16%). Conclusion In our study, 120 Enterococcus isolates in all, mostly of Enterococcus faecium and Enterococcus faecalis, were isolated from different clinical specimens for our investigation. Teicoplanin showed the highest sensitivity among the isolates. The study of Enterococcus species prevalence and antimicrobial susceptibility is vital for informing infection control and treatment strategies, enhancing antibiotic stewardship, and guiding public health policies.
