Abstract
This article reports on the occurrence and diagnosis of Aujeszky’s disease in a dog. The procedure for isolation and identification of Aujeszky’sdisease virus was described. A dog of unknown breed aged about two years died of Aujeszky’s disease after consuming animal offal (internal organs: lungs, spleen, kidneys) fed by the owner after slaughtering piglets and preparing meat for cooking. As early as 24 hours after consuming the offal, the dog manifested characteristic symptoms of Aujeszky’s disease, which were immediately recognized by the veterinarian. The death occurred within less than 24 hours upon first clinical signs of disease. Aujeszky’s disease virus was isolated and identified from brain and internal organ (lung and spleen) samples of the dog at the Department of Virology of the Scientific Veterinary Institute „Novi Sad“. Isolation and identification of the virus was performed on PK-15 porcine kidney cell line and using nested PCR technique.
Highlights
Aujeszky’s disease (AD), known as Pseudorabies, is an infectious disease caused by a Suid herpesvirus 1 (SHV-1) from the family Herpesviridae, subfamily Alphaherpesvirinae
Reported incubation periods in dogs and cats range from 2 to 10 days, but most cases probably become apparent in 2-4 days (CFSPH, 2017)

Summary
Aujeszky’s disease (AD), known as Pseudorabies, is an infectious disease caused by a Suid herpesvirus 1 (SHV-1) from the family Herpesviridae, subfamily Alphaherpesvirinae. The virus infects the central nervous system and other organs, such as respiratory tract of dogs, cats, cattle, sheep, rabbits, foxes, etc. Pigs are considered as a natural host and the main reservoir of the virus but the characteristic clinical picture is manifested only in the suckling and sometimes in the weaned piglets. Pets can get infected by consuming contaminated raw pork meat. After consuming meat contaminated with AD virus, the virus enters nerve endings in the mucosa and spreads to the brain along nerve axons (Kotnik et al, 2006). The incubation period is usually 2-6 days in the category of suckling pigs and less than 9 days in cattle and sheep. Reported incubation periods in dogs and cats range from 2 to 10 days, but most cases probably become apparent in 2-4 days (CFSPH, 2017). The infection of non-adapted species (such as dogs), results with death within few hours after showing of the first symptoms (Kotnik et al, 2006)
