Antibiotic and Heavy Metal Resistance of Enterococcus faecalis Isolated from Eastern Mediterranean Sea

35933

In this study the resistance of 158 Enterococcus faecalis isolates recovered from Mediterranean Sea to 15 different antibiotics and four heavy metals was investigated by agar diffusion and agar dilution methods respectively. A high incidence of resistance to gentamicine (98.7%), ciprofloxacin (77.8%), imipenem (77.2%) and levofloxacin (72.8%), as well as almost an absence of resistance to vancomycin (3.2%), minocycline (13.3 %) and quinupristin-dalfopristin (13.3%) was found among the isolates. Multiple antibiotic resistance (MAR) index ranging from 0.2 to 0.93. Most isolates were showed tolerance to different concentrations of heavy metals. These results suggest that Eastern Mediterranean Sea has important proportion of antibiotic and heavy metal resistant Enterococcus faecalis and these bacteria can be responsible a potential risk for public health.
