title: Effects of prednisolone on the development of immune responses to canine distemper virus in beagle pups.
abstract: Effects of oral prednisolone (OP) on the development of immune responses of Beagle pups to canine distemper virus (CDV) were studied. Dogs were treated with OP for 21 days, twice a day for the first 7 days, once a day for the next 7 days, and on alternate days for the last 7 days. Dogs given dosages of OP (1 mg/kg and 10 mg/kg) showed a normal in vivo immunogenic response after CDV vaccination and survived a virulent CDV challenge exposure, whereas non-treated, nonvaccinated dogs became ill or died after challenge exposure. The most marked effect of corticosteroid treatment on the immune system was the graded phytoimmunosuppressive effect upon the lymphocyte blast transformation test.
