It's actually generally inexpensive $3.50 for 10ml of 500mg/ml. I do understand that it is meant for IM or IV use, but this still goes back to my earlier comment about Vanco, as long as we're suspending it in the water column it's going to get into the Nem's body. Beyond that, we don't know much more about what it's reactions could be as we do with a "normally" oral medication like Cipro.
Maybe I need to look up the method of delivery for plants, but I feel it's an unexplored option with something with a little more coverage, or at least different coverage, than Cipro is currently giving us.
Edit:
This site seems to have a pretty solid list of what we have potentially at our disposal. There's not much I can think of that we use in the vet industry on a daily basis that isn't listed here:
