Speciation of Enterococci to Predict Antibiotic Resistance Pattern: A Study from Teritiary Care Hospital
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 3
Abstract
Background: Enterococci has recently emerged as a medically important pathogen causing hospital as well as community acquired infections. Detection of multi drug resistance is major health concern among the enterococci species in the hospitalized patients.However at present prevalence of E.faecium is more common than E.faecalis in hospital acquired infections. So exact speciation may help to predict the antibiotics to be used. Objective: To isolate and speciate Enterococci from the clinical specimens and to detect their antibiotic susceptibility pattern. Materials and methods: This study was conducted over a period of 2 years from January 2013 to January 2015.Clinical samples were received from various departments of Narayana Super speciality Hospital in the form of pus, urine, blood and peritoneal, synovial, ascetic fluids ect. Antibiotic sensitivity patterns were determined by Kirby-Bauer’s disc diffusion method after isolation and speciation of enterococci. The work is carried out at Department of Microbiology, Narayana Medical College. Results: During this period total of 150 clinical samples were processed for the presence of Enterococci and its speciation and antibiotic sensitivity test. Among the 150 samples processed 83% were E.faecalis and 67% were E.faecium. In our study more number of Enterococci were isolated from Pus followed by urine and blood. Among antibiotic resistance of Enterococci species, E.faecium showed more resistance than E.faecalis. Conclusion: Our study findings are contrary to the belief. So correct speciation can help to predict antibiotic resistant pattern and treatment. Though the study has not been included the prevalence of fecal carriage of enterococci and vancomycin resistant enterococci (VRE),microbiologists and clinicians should know the threat of these specie. Surveillance for screening tests to detect fecal VRE carriage among the hospitalized and general population must be carried out for effective therapy and infection control measure to implement
