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.

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.

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.

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.

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.

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.

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.
