As for the recent status of gram-positive bacteria, the proportion of methicillin-susceptible Staphylococcus aureus (MSSA) varied among antimicrobials, and the proportion of methicillin-resistant Staphylococcus aureus (MRSA) accounted for approximately 50%, which remained higher than that in other countries, though the proportion were declining over the past years. Despite the global problem of increasing vancomycinresistant enterococci, in Japan, the proportion of vancomycin-resistant Enterococcus faecalis remained lower than 0.05%, and that of Enterococcus faecium remained at 1% or lower. The proportion of penicillin-resistant Streptococcus pneumoniae (PRSP) accounted for approximately 40% of all detected pneumococcus in cerebrospinal fluid (CSF) samples, though the figure varies from year to year, because only around 100 CSF samples are tested. The proportion of PRSP was low for non-CSF samples at below 1%, and below 5% even adding penicillin intermediate resistant bacteria.
