Porcine reproductive and respiratory syndrome virus-induced immunosuppression exacerbates the inflammatory response to porcine respiratory coronavirus in pigs
We performed a comprehensive analysis of innate and adaptive immune responses in dual-virus infected pigs to understand whether a pre-existing immunomodulatory respiratory viral infection affects the overall immunity to a subsequent porcine respiratory coronavirus (PRCV) infection in pigs.
Thailand - Unexpected increase in morbidity or mortality of a listed disease
An increase in the morbidity/mortality has been observed in the area of Amphur Ban-Ra-Kam (Phitsanulok province) and PRRS is suspected based on clinical signs.
Vietnam - Meat prices to rise 15-20%
Prices of meat in Vietnam particularly pork, will increase between 15% and 20% from a year earlier during the upcoming Lunar New Year holiday.
Vietnam resumes pig slaughtering in PRRS-affected areas
Vietnam has allowed abattoirs in areas affected by blue-ear disease to resume slaughtering pigs, said Hoang Van Nam, Director of the Department of Animal Health.
Canada - PRRS costs canadian swine industry 130 million dollars per year
The Guelph based George Morris Centre estimates Porcine Reproductive and Respiratory Syndrome is costing the Canadian swine industry a minimum of 130 million dollars per year.
Germany introduces health certificate for piglets
After several years of preparation and grants from the German government, the Deutsche Raiffeisen Verband (DRV), in collaboration with various German producers’ associations, will soon be launching a certification system for piglets. This certification system is a transparent counterpart of the Danish and Dutch model.
Sanitary Equilibrium: The role of PCV2 vaccines
The most common problems are due to interference with maternal antibodies and coincidence of vaccination with a recirculation of PRRS: viremic animals.
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.
Vietnam - Blue ear disease flattens corn demand
Pham Duc Binh, Deputy Chairman of the Vietnam Animal Feed Association, said Vietnam will import 1.25 million tonnes, the same as last year.
Vietnam - Pig farms in Dong Nai close due to PRRS
The Blue ear disease that has hit 13 provinces in Vietnam has resulted in a huge loss for farmers.
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.
