Baytril (enruofloxacin) is converted to ciprofloxacin in the animal bodies to some extent and in humans. Both entities can have antibacterial activity. Can both entities have toxicities also? Hard to prove in living creatures since by giving enro-, some cipro- is produced. . Maybe studies could be done in tissue culture where little metabolism might occur.

I would guess the researchers felt it was not worth the effort to tease out which entity was the greater cause of the problems and why.
Not enrUofloxacin....Enro-.
Apologies for the misspelling.
