General question to everyone but particularly to shelters. Has anyone seen the following reaction? Almost exactly two weeks following vaccination with IMRAB the ferret becomes extremely lethargic; quits eating and drinking; weakness to the point that it can hardly walk; followed in some cases by black tarry stool, slight fever, chills, congestion and then in two cases death. We observed our first nearly a year ago. The pathology report found nothing abnormal. Since then, we've had three more; one of which died and the other two recovered - treated with amoxicillin, Sulcrafate, lots of 'force feeding and hydration', We are now seeing our fifth, vaccinated almost exactly two weeks ago. Considering the number of ferrets we handle in the shelter it may be coincidence, but the consistent two week figure makes me suspicious. Dick B. [Posted in FML issue 1319]
