Porcine parvovirus infection (PPV) is a common and important cause of infectious infertility. PPV is a robust virus that multiplies normally in the intestine of the pig without causing clinical signs and is ubiquitous in pig populations world-wide.

What is PRRS in pigs?

PRRS is an acronym (porcine reproductive and respiratory syndrome) for a viral disease characterized by two overlapping clinical presentations, reproductive impairment or failure in breeding animals, and respiratory disease in pigs of any age.

How is the porcine parvovirus treated?

There is no treatment for porcine parvovirus.

What is Aujeszky’s disease?

Aujeszky’s Disease (AD) or Pseudorabies is a notifiable infectious disease of pigs. It is caused by a herpes virus and other species are also susceptible, for example, cattle, sheep, dogs and cats. It is not transmissible to humans.

How long does porcine parvovirus last?

The acute disease can last up to 8 weeks and after that decline for 4 to 6 weeks, followed by shorter periods of time with the presence of mummies during other 4 to 6 weeks. The virus can take up to 4 months in infecting all the sows and gilts of a naive population.

Is PRRS treatable?

Since PRRS is a virus, antibiotics are generally considered unsuccessful in treating the primary infection. However, using antibiotics correctly can reduce the presence of other pathogens in the herd.

What are the symptoms of PRRS?

Symptoms of acute PRRS virus infection in pigs infected in utero or shortly after birth include severe dyspnea (labored breathing or thumping), lethargy, inappetence, fever, edema or swelling of the eyelids, and a blue or red discoloration of the ears or hindquarters. Pre-weaning mortality may approach 100%.

Is there a vaccine for parvovirus?

Dogs and puppies can be vaccinated against parvovirus from the age of six weeks. A puppy should have their first vaccine at six to eight weeks old. They will then need a second vaccine two weeks later. After that, they will need a booster vaccine at one year old.

How is Aujeszky’s disease transmitted?

Aujeszky’s disease is generally spread by direct, nose to nose, contact between pigs. The virus can also become airborne and spread over longer distances. It can also be spread through objects contaminated with the virus.

What are two causes of porcine fetal mummification?

There are two possible causes of mummies. First, a piglet dies because there is a large litter and insufficient space in the womb. Second, there is infectious disease, usually of a progressive nature, at any stage during the period of pregnancy.

Can parvo cause infertility?

Canine parvovirus infection has been implicated by some breeders as a cause of infertility in their kennels.
