Characterization and antimicrobial susceptibility pattern of clinical isolates of Enterococci at a tertiary care hospital in Mumbai, India

Context: Enterococcus is considered an important nosocomial pathogen because of its intrinsic as well as acquired antibiotic resistance. It also has the potential of transferring vancomycin resistance to other organisms such as Listeria monocytogens and Staphylococcus aureus. Aims: The objective of the present study was to determine antibiotic-resistance pattern of Enterococcus with special reference to vancomycin. Settings and Design: A total of 54 clinical isolates of enterococci were collected during the study period of 1 year at a tertiary care center in Mumbai. Material and Methods: Speciation and antibiotic sensitivity testing were done by standard procedures. Minimum inhibitory concentration (MIC) to vancomycin was carried out by agar dilution method. Results: Speciation and antibiotic sensitivity testing were done by standard procedures. The MIC to vancomycin was done by agar dilution method. Conclusions: Vancomycin, Linezolid, and Teicoplanin can be safely used for the treatment of serious enterococcal infections.
