Abstract :

This study was conducted to isolate, identify, speciate enterococci from the various clinical specimens and study their antibiogram and also to determine the minimum inhibitory concentration of high level gentamicin and vancomycin.

The present study was carried out in a bacteriology laboratory, Microbiology Department, RIMS Hospital. The total of 54 Enterococcus species were isolated from various clinical specimens such as urine, blood and pus. Urinary isolates were 43(81.62%), blood isolates were 7 (12.96%), pus isolates were 3 (5.55%). E.faecalis is a predominant species 33 (61.11%) followed by E.faecium 18 (33.33) and E.gallinarum 3 (5.55%). Antibiogram of the enterococcal isolates were, penicillin resistance 50 (92.5%), ciprofloxacin resistance 44 (81.8%), nitrofurantoin resistance 8 (14.8%) and HLG resistance 21(38.88%). All the isolates were sensitive to vancomycin and linezolid. MIC for HLG was determined by E–tests in which 21 isolates were ≥ 1024µg/ml and 33 isolates were ≤ 4 µg/ml. Determination of MIC for vancomycin was also performed by E–tests in which all the isolates were ≤ 4 µg/ml.
