The great sensitivity of carnivorous animals to the Aujeszky's disease virus makes them an indicator of the presence or absence of the causative agent on a farm. The massive spread of rodents and especially cats, from porcine industrial farms with reproductive disorders, is the reason to investigate the clinical manifestations and pathomorphological changes induced by the vaccine strain and two terrain uterotropic strains of the Aujeszky's disease virus in dogs and cats. Kittens of 50–60 and dogs at 35–40 days of age were used. It was found that strain Mogila was highly virulent for dogs and cats, and the vaccine strain was more pathogenic for dogs and less pathogenic for cats. Cats had no itching. Pathohistological changes were localised in the nervous and respiratory system. They have the character of nonsuppurative encephalitis and interstitial pneumonia. In the lungs of cats, infected with strain Mogila, a fibrinous-necrotizing inflammatory response was observed.
