Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease found in swine (pigs and wild boars). It is caused by a virus belonging to the Arterivirus family which also contains the causative agents of equine arteritis and simian haemorrhagic fever. The PRRS virus is a small (50-60 nm), enveloped RNA virus with at least two different membrane proteins at its surface which are probably the antigens that elicit the serological responses detected in infected pigs. The virus has immunosuppressive activity and kills the macrophages in the lung inside which it replicates. This probably helps compromise pulmonary resistance to other infectious viruses and bacteria. The PRRS virus causes respiratory and influenza-like symptoms as well as fertility problems, abortion and the birth of runts. Viral particles are secreted in all bodily secretions, including nasal secretions, faeces and sperm as well as in aborted foetal tissue and placenta. This disease is spread throughout the world and affects domesticated pigs in particular.
