Use of NFIDs does not prevent hematogenous transmission of PRRSV.

Aerosols of PRRS virus were exposed to one of four doses of UV254 under nine combinations of temperature (n = 3) and relative humidity (n = 3).

The economic loss varied between €59 and €379 for one sow per 18-week period outbreak.

Host response to experimental PRRS virus challenge has a strong genetic component and a QTL on chromosome 4.

The evolution of infectiousness was mainly correlated with the course of viral genome load in blood.

A total of 1279 Eurasian wild boar (Sus scrofa) sera were collected from 2000 to 2011 to reveal time changes in serum antibody prevalences against selected infectious agents (PCV2, PRRSV, HEV and Erysipelothrix rhusiopathiae.

All filter types equally reduced the risk of airborne transmission of both pathogens, compared to non-filtered controls, supporting further application in the field.

The objectives of this abstract are to present the methodology followed in PRRS area regional control and elimination (ARCE) projects in the United States and to report the advancement of these projects.

A total of 4889 animals, ranging in age from 9 to 10months, from 48 batches of pigs belonging to an equal number of herds, were included in the study.

This paper summarizes observations recorded over a 4-year period regarding the ability of a 1-night period of downtime to prevent mechanical spread of PRRS and Mycoplasma hyopneumoniae between pig populations by personnel and fomites.

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.
