Stability of porcine reproductive and respiratory syndrome virus and antibody in swine oral fluid
Conventional serum storage protocols (freezing or refrigeration at 4°C) preserves PRRSV and anti-PRRSV antibody in oral-fluid diagnostic samples without the use of preservatives.
The genomic diversity of Chinese porcine reproductive and respiratory syndrome virus isolates from 1996 to 2009
Since it was first reported in 1995, porcine reproductive and respiratory syndrome (PRRS) has become one of the most important swine diseases in China. A large number of field PRRSV strains have been isolated from different regions of China at different times, especially after a highly pathogenic PRRSV emerged in 2006.

Genetic resistance to PRRS
There is sufficient genetic variation in host response to infection to allow future breeding goals for enhanced resistance or tolerance so that there are grounds to believe that it may be possible to breed commercial animals that have increased genetic resistance or tolerance to the disease.
Cambodia bans pig imports as blue-ear swine disease spreads
Cambodia has banned the import of pigs from Vietnam and Thailand after swine infected with blue-ear disease were smuggled into the country from neighbouring Vietnam.
Simultaneous detection of porcine circovirus type 2, classical swine fever virus, porcine parvovirus and porcine reproductive and respiratory syndrome virus in pigs by multiplex polymerase chain reaction
A multiplex polymerase chain reaction (PCR) was designed for the simultaneous detection of four viruses involved in reproductive and respiratory failure in pigs: porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), classical swine fever virus (CSFV) and porcine reproductive and respiratory syndrome virus (PRRSV).
Haptoglobin and C-reactive protein as biomarkers in the serum, saliva and meat juice of pigs experimentally infected with porcine reproductive and respiratory syndrome virus
The correlations found suggest that the measurement of Hp and CRP in saliva and meat juice could serve as complementary, or possibly alternative, biomarkers of pig herd-health.
Long-distance airborne transport of infectious PRRSV and Mycoplasma hyopneumoniae from a swine population infected with multiple viral variants
Airborne transport of PRRSV 1-8-4 and M hyo 232 occurs over longer distances than previously reported and that both pathogens remained infectious.
