Pasteurella HELP!

So I've recently noticed 3 of my bunnies have started sneezing and have runny noses. I'm almost certain its pasteurella so heres my questions. Can pasteurella be treated? Which antibiotics would I need? What would the dosages be? Would I be better off culling the 3 sick bunnies? I've never had a problem with pasteurella before and am quite worried... any advice would be appreciated! Thanks!

Is there a reason you suspect pasturella (to my understanding, it's the chronic runny nose condition) as opposed to a more permanently treatable upper respiratory infection?

To answer questions about medication and dosages, you'll need to go to a rabbit experienced vet. Different URIs will respond to different antibiotics, and many owners go through a trial and error process to find the right one. Dosage will depend on your rabbits weight and medication type.

Before you do anything drastic you need to have the vet culture the discharge to confirm if it’s pasteurella or not. Have you isolated these 3 from your others?
I see that you are breeding so it’s very important to confirm before you consider culling.
