Pseudo rabies virus

Young swine are very susceptible and can develop severe CNS symptoms. Mortality can reach percent in piglets. Clinical signs in weaned pigs, depends on age.

Few weaned pigs develop a fatal CNS disease but more often will develop a respiratory disease. Grower finishing swine typically develop only a respiratory disease component.

Adult swine may have a respiratory disease component and if pregnant, depending on the trimester of pregnancy, may abort, have stillborns or give birth to weak piglets. Pigs of all ages display a generalized febrile response, anorexia, and weight loss. Infected pigs remain latently infected following clinical recovery. The US commercial industry has remained free. If you are testing for interstate shipment, contact the State animal health official in the State of destination for specific requirements.

The virus moves within the herd through direct animal-to-animal contact, or indirectly via respiratory excretions. Snotty nasal discharge can stick to panels, workers' clothing, feed, bedding, boots, trucks, and other equipment.

Non-infected hogs can pick up the disease after contacting such contaminated items. PRV is very susceptible to pH levels below 4 and above 9. Survival is temperature dependent. The virus can survive only a few hours on clean concrete or mixed in dirt. The PRV virus can survive up to three days on plastic and steel. Two days is the virus' survival time in manure and lagoon water. Whole corn can sustain the virus up to four days. The PRV virus mixed with body excrement can survive on the soil for up to six days.

Under optimal pH and temperature conditions, some virus particles may survive as long as 40 days to days. However, these conditions are unlikely to exist. Management procedures that revolve around sound biosecurity practices are very important in all disease control programs.

Any infected herds have been promptly depopulated when found, and intense epidemiological investigations have been conducted to ascertain that no viral spread to commercial production swine has occurred. Indemnity Information: for questions in regards to pseudorabies indemnity contact:. Humphrey usda. OR John A. Korslund aphis. PRV is a reportable disease in all states. PRV can be devastating to your breeding animals and young piglets in particular.

If you have any serious breeding, nervous, respiratory or sudden unexplained death issues with sows and newborn piglets in particular, call your veterinarian to investigate. The veterinarian will most likely get blood samples and tissues from dead piglets, for example to submit to the veterinary diagnostic lab to help determine a diagnosis. If the cause turns out to be PRV state and federal animal health officials will also become involved in the investigation.

Contact with feral swine is by far the most common method of PRV getting into your swine herd, so be sure this cannot happen through double fencing and other measures if feral swine are present in your area.
