it is an infection by S aureus, the bacterium hs a wide ranging
resistance to most antibiotics, the organism swaps resistant genes via
plasmid trnsfer/conjugation

Scincxe antibiotics have no affect on it, an infection can spread
unhindered an a small cut, post operative infection can result in
devistating results

this is true, one of the last major Antibiotics to have some effect is
called Vancomycin, however this has side effects, it is in use in the
UK anyway

there also exists an organism called VRE, vancomycin resistant
enterobacter, It is resistant to Vancomysin, there is not a readily
available treatment for this, new drugs are being tested.

My two year old nephew contracted VRE after a house fire in june 95,
he developed menengitis as a result of VRE and is now suffering from
severe brain damage.  I know that the doctors at Gt Ormand Street
Hospital (London) used a test drug from france, but I am not sure of
its name. the drug appeared to work, but liver damage is a significant
side effect

the relapse rate is significant, I understand it to be in the nature
of 20 % ( don't quote me) It is theoreticl possible for them to lose
the infection but probably unlikely
