3= great. Use an antibiotic empirically if it is a 3.
2.5 = the best we got, but I sure wish we had better. OK to use empirically as we do not have any other choice.
2= adequate if susceptible, use with caution (ie know what you are doing and local susceptibility patterns) but do not rely on it empirically if you do not have susceptibilities.
1.5 = if it is susceptible its great, but is almost never susceptible.
1= no way dude. You want a dead patient?
R = resistant
"?" = looks good in a test tube
"." = placeholder pending data
