Types of hospital superbugs?

The two biggies just now are MRSA (Methicillin Resistant Streptococcus aureus) -- various strains of strep that resist all or most pennicillins, and VRE (Vancomycin Resistant Enterococcus) -- a bug from the gut that, as it says, resists Vancomycin -- one of the newer big guns in antibiotics. These are usually successfully treated with meds oxazolidinones (Zyvox) and daptomycin (Cubicin) (Gram positive only). These tow comparatively new medications take a different pharmokinetic approach to bacteria suppression.
