Abstract :
Background: Enterococci are common commensal of gastrointestinal tract of human beings. They stand as one of the
major causative agent in Nosocomial infections. Enterococcus has gained clinical importance due to their
intrinsic and multidrug resistance. Speciation of Enterococci is important as faecalis being sensitive to
vancomycin whereas faecium remains to be resistant, so isolating and treating Enterococcus has become
an important task.
Objective: 1). To determine the species of Enterococci. 2). To determine the antibiogram of Enterococci.
Materials and Methods: A Prospective study was conducted at a tertiary care hospital in MIMS, Mandya.
Standard protocols were followed for isolating & speciation of Enterococcus. As per CLSI guidelines
antibiotic susceptibility testing was done.
Results: Out of 42 Enterococcal isolates majority were isolated from urine (59.52%) followed by pus
(26.19%), blood (9.52%) and sterile body fluids (4.77%).
Enterococcus faecalis were (88.1%) and Enterococcus faecium were (11.9%). Among gender distribution,
majority (54.77%) were females and (45.23%) were males. All the isolates were susceptible to Linezolid.
Maximum resistance was seen against Penicillin and Tetracycline.
Conclusion: The appropriate infection control measures, use of antibiotics prescribed based on sensitivity
obtained and avoid the empiric use of antimicrobials by clinicians can prevent the burden of drug resistance
in Enterococcus.
