I don't really know much about it as there's limited info on it with rabbits, and even more limited with chloramphenicol treatment. But I know it can be a more common bacteria in rabbits with mastitis, and is easily passed to newborn kits, having a high rate of mortality (for the newborn kits).

Here are a few articles I came across that mentioned staph, and one lengthy one talking about ear infections. Worth a read.

Citation Excerpt :
Azithromycin has a broad spectrum of action against Gram positive and Gram negetive bacteria and both aerobic and anaerobic organisms. Azithromycin may, therefore, be efficacious over a wide range of infections in rabbits because it has been shown to be effecitive in treating Staphylococcus spp., Streptococcus spp., Haemophilus spp., Pasteurella spp., Clostridium spp., Bacteroides spp., Mycoplasma spp., Toxoplasma spp., and other common pathogens.
And one just generally about abscesses.

I'm presuming your vet shared with you the precautions needed when using chloramphenicol, and handling it safely?
