What clinical sign is commonly seen in weaned pigs affected by Pseudorabies?

In weaned pigs affected by Pseudorabies, the most commonly observed clinical sign is the presence of neurological symptoms. Pseudorabies, caused by the suid herpesvirus-1 (SHV-1), primarily impacts the nervous system of infected pigs. Symptoms may include tremors, ataxia, and possible seizures. These neurological manifestations occur due to the virus’s ability to invade the central nervous system, leading to inflammation and dysfunction.

While diarrhea, high fever, and abdominal pain may also be seen in various pig diseases, they are not the hallmark symptoms of Pseudorabies. The neurological signs stand out as distinctive features of this particular viral infection, making them the most relevant clinical signs to associate with weaned pigs affected by Pseudorabies. Understanding this is key for accurate diagnosis and management of affected pigs in a veterinary setting.
