Line graph demonstrates the percentage of E. faecalis resistant to high-level streptomycin, by survey year. Survey years include 1995, 1999, 2003, 2005, 2007, 2009 and 2010. The figure includes line graphs for invasive, non invasive, and all isolates In E. faecalis, high level streptomycin resistance decreased significantly from 1995 to 2003 (18.1% to 8.6%) but has been relatively stable since then. In 2010 the percentage of invasive isolates resistant to high level streptomycin (8.1%) was similar to non invasive isolates (8.2%)
