Symptoms of the virus in these animals are anorexia, excessive salivation, spasms, convulsions and intense itching followed by paralysis and then death. Pseudorabies is not related to the rabies virus and does not infect people. This disease is of special concern to domestic hog owners because it can weaken pigs and cause abortions and stillbirths, thus decreasing production and profits. Once infected, the hog is a lifetime carrier and will periodically shed the virus through the mouth and nose. Transmission of the disease can be through direct contact, contaminated feed and water, ingestion of infected tissues, or contaminated trailers.
Swine brucellosis can cause infertility in boars and abortions in sows.
This disease can also cause a loss of production and profit in domestic swine operations. Swine brucellosis is transmitted through reproductive discharges such as semen and afterbirth and once infected a hog is a carrier for life. The only effective way to control this disease is to test and remove infected individuals, a task impossible to do in a wild population. Swine brucellosis is contagious to humans and symptoms may range from severe flu-like symptoms to arthritis or meningitis. There is no cure for this disease in animals while humans can be treated with antibiotics in an attempt to clear the infection.
