[An atypical case of Aujeszky's disease in a dog (author's transl)].

Two cases of Aujeszky's disease in a cat and a dog belonging to the same owner are reported. The two animals each were five months of age. The symptoms shown by the cat were typical of Aujeszky's disease: intense itching, salivation and the head bent to one side. The main symptoms shown by the dog consisted in salivation, ptosis of one eye, a drooping ear, the head bent to one side and ataxia. As itching was not observed in the dog and the animal had spent the first months of its life in wooded surroundings, it could also have been affected with rabies, although it had been inoculated with LEP-Flury vaccine forty days prior to importation. It is of importance to the practitioner to know that itching may be absent in dogs with Aujeszky's disease and that rabies should also be suspected in these cases. Only a laboratory diagnosis will be conclusive. Studies were negative for rabies, the virus of Aujeszky's disease being found to be present in the two cases. The source of infection probably consisted in contaminated pork offal (larynges).
