In this review paper published in Veterinary Sciences, Valeria Lugo, a student working with Drs. Corzo and Goyal at the University of Minnesota, discusses the current knowledge of PRRS survivability based on temperature and other environmental conditions. The publication is available in open access on the journal’s website.
The manuscript reviews what has been published regarding PRRSV persistence in/on:
- Tissues and serum
- Solid fomites
- Animal feed
- Fecal slurry and other liquids
- Aerosols
- Insects
- People
- Pork meat
- as well as the impact of temperature
Abstract
Porcine reproductive and respiratory syndrome (PRRS) is one of the most economically important diseases of swine, with losses due to poor reproductive performance and high piglet and growing pig mortality. Transmission of porcine reproductive and respiratory syndrome virus (PRRSV) may occur by both direct and indirect routes; the latter includes exposure to PRRSV-contaminated fomites, aerosols, and arthropod vectors. This review has collected available data on the ex-vivo environmental stability and persistence of PRRSV in an effort to highlight important sources of the virus and to determine the role of environmental conditions on the stability of the virus, especially temperature. The ex-vivo settings include fomites (solid, porous, and liquid fomites), insects, people, and pork meat, as well as the role of environmental conditions on the stability of the virus, especially temperature.
