There are different types of MRSA: hospital and community acquired. The hospital acquired is MUCH worse. It's resistant to many more antibiotics. In fact, they have found some that are resistant to vancomycin, which is scary beyond belief.
The community acquired can be treated with more antibiotics, including some of the older, cheaper ones... so far.
Staph is the big news this week, but many, many bugs are becoming resistant to our antibiotics. Unfortunately, there's a lot more money in erectile dysfunction drugs than there is in antibiotics. So there just aren't that many new antibiotics coming down the pipe.
