Porcine Reproductive and Respiratory Syndrome [PDF]
Outbreaks of undiagnosed reproductive failure occurred in North Carolina, Minnesota, and Iowa during 1987-1988 and were characterized by the presence of both respiratory and reproductive signs in swine herds. 29,35,36 The disease was referred to as mystery swine disease because no definitive cause could be assigned to it.

Porcine reproductive and respiratory syndrome in China
Porcine reproductive and respiratory syndrome (PRRS) is an economically important viral disease for the pig industry worldwide. This disease has brought great losses to the Chinese pig production in recent years, particularly following the emergence of the highly pathogenic PRRS virus (PRRSV), and has become an intractable problem for the development ...

An Outbreak of Porcine Reproductive and Respiratory Syndrome in Japan.
An emerging swine disease principally involving periweaning piglets was examined. The disease was clinically characterized by lethargy, fever, emaciation, coughing, and severe abdominal breathing, hence colloquially named "Heko-heko" disease. The consistent lesions in affected piglets were diffuse interstitial pneumonia with pronounced type II ...

Characterization of the attachment and infection by Porcine reproductive and respiratory syndrome virus 1 isolates in bone marrow-derived dendritic cells [PDF]
Porcine reproductive and respiratory syndrome virus (PRRSV) is known to infect porcine dendritic cells (DC). Previous studies indicated that different PRRSV1 isolates regulated differently the cytokine profiles and expression of surface molecules of DC ...
