Impact of selected parameters on efficacy of pen based oral fluid collection from pigs
Oral fluid testing is becoming important tool in diagnostic and epidemiological studies of PRRSV, PCV2 and SIV infections. However, sample collection requires understanding of pigs behavior as many of it aspects directly impact the yield of oral fluid. The aim of the present study is to analyse factors affecting the amount of oral fluid collected in standard pig herds in Poland.
Median infectious dose (ID50) of PRRSV for young pigs via aerosol exposure
The objective of this research was to quantify the likelihood of PRRSV transmission via aerosol as a function of exposure dose. This data is critical to understanding of airborne transmission of PRRSV between pigs, within herds, and between herds.
A comparison of PRRS virus PCR testing methods: Serum PCR versus oral fluid PCR
The objective of this study was to evaluate the correlation between serum PRRSv PCR positives and oral fluids PRRSv PCR positives, to evaluate the detection dynamics between serum and oral fluids PRRSv PCR positives, and to determine the effects of pooling samples.
Thailand - Unexpected increase in morbidity or mortality of a swine 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.
Aerial mapping: Adding to the swine industry’s toolbox for area regional disease control
Area regional disease control (ARDC) strategies are an important tool in the swine industry due to the ability of many swine diseases, most notably PRRS, to spread by methods other than direct animal contact.
Oral fluid collection from individually-penned, PRRSV-infected boars
The objectives of this study were to determine if oral fluid samples 1) could be collected from individually-housed mature boars under field conditions and 2) could be used to detect PRRSV infection.
New Zealand extends raw-pork import ban
The New Zealand high court has stopped the importation of raw pork that pig farmers fear could infect animals in NZ with a disease that kills unborn and young pigs.
Global science network to protect against animal diseases
Defra is leading an international network research, funded by the EU, linking thousands of scientists across the world.
New Zealand - Pork Import Health Standards effectively manage risk
The Ministry of Agriculture and Forestry (MAF) issued updates to four Import Heath Standards for pig meat, pig meat products and by-products from Canada, the EU, Mexico and the USA.
Canada - Sask Pork prepares to launch western Canada PRRS-Free herd certification pilot project
The Saskatchewan Pork Development Board hopes to begin testing swine herds in western Canada for PRRS-Free Herd Certification within the next few months.

ArticlePhilippines: Swine industry situation and outlook
Despite the increases in the pork supply, deficit scenarios are expected in the 1st and 2nd quarters of 2011.
An evaluation of ultraviolet light (UV(254)) as a means to inactivate porcine reproductive and respiratory syndrome virus on common farm surfaces and materials
The results obtained in this study suggest that UV(254) is an effective means to inactivate PRRSV on commonly encountered farm surfaces and materials and inactivation can be accomplished following 10min of exposure.
China plans compulsory animal vaccination
The Ministry of Agriculture and Ministry of Finance jointly filed a new regulation on animal vaccination for prevention of epidemic diseases in 2011.
Mongolia - First occurrence of PRRS
The World Organisation for Animal Health (OIE) has reported the first occurrence of PRRS in Mongolia.
