Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
Enterococci are one of the common causes of Nosocomial urinary tract infection (UTI)Worldwide . Objective of this cross sectional study was to identify different species of Enterococci causing nosocomial urinary tract infection in a tertiary care hospital. In addition, antibiotic susceptibility pattern of the isolated strains to set up an Empericial therapy for reduction of morbidity& mortality. Standard microbiological procedure and related automation were followed to perform the study. Out of total 369 urine samples from selected patients, 37 were culture positive (almost 10%). Out of 37 culture positive cases, Enterococci were isolated in 11 cases (29.7%). Enterococcus faecalis & Enterococcus faecium were found in five and four cases respectively. Two Enterococcus gallinarum strain was also isolated. However Escherichia coli were isolated in 19 cases (51.35%). All isolated Enterococcus gallinarum and Enterococcus faecalis were sensitive to both Benzyl penicillin and Ampicillin although all isolated Enterococcus faecium were resistant to both of the drugs. All isolates of Enterococcus faecalis and Enterococcus faecium were sensitive to Vancomycin and Linezolid but Enterococcus gallinarum isolates was Vancomycin resistant (MIC value is ≥32μg/ml). In addition, the resistance pattern was van-A type (fingerprint was identified by VITEK 2Advanced Expert System). All of the Enterococcus faecalis isolates were resistant to Quinupristin & Dalfopristin whereas isolated Enterococcus faecium were sensitive to those antimicrobials. All of the isolates were sensitive to Nitrofurantoin except one Enterococcus faecium isolate (MIC value=64μg/ml) was intermediately susceptible to the drug.
