The primary objective of this 7-month study was to determine the prevalence of porcine pathogens of the tonsil of the soft palate, principle tonsil of the pig, of swine at slaughter.

The filtering of incoming air to swine facilities located in dense regions of production has been proposed as a means to reduce the risk of airborne transport of PRRSV.

The purpose of the present study was to determine whether oral fluid samples could be used to monitor individually-housed adult boars for PRRSV infection.

The objectives of this study were to determine if co-infection of piglets with PRRSV and PCV2 has any affect on PCV2 shedding characteristics and if there are differences in shedding patterns between PCV2 subtypes (PCV2a and PCV2b) in co-infected pigs.

We evaluated the efficacy of serum inoculation to immunize gilts in prevention of reproductive PRRS following late-gestation challenge with the “homologous” virus.

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.
