In vitro antimicrobial susceptibility study in clinical isolates of Streptococci and Enterococci

Abstract

Streptococci and Enterococci are becoming increasingly responsible for nosocomial infections such as pneumonia, arthritis endocarditis, bacteraemia, urinary tract infection, and neonatal sepsis. The aim of the present work was to study antimicrobial sensitivity pattern of Enterococci and Streptococci isolated from different clinical specimen. Antibiotic susceptibility was performed by agar disc diffusion method. Enterococci and Streptococci species were highly resistant to different antibiotics studied, while vancomycin resistance Enterococci were not found. Thus, it could be concluded that the high activity of vancomycin encourages its further administration for infections caused by Enterococci.
