PEDv – Swine in Minnesota

Evaluating the Efficacy of Boot Baths with Wet and Dry Disinfectants for Porcine Epidemic Diarrhea Virus and Porcine Reproductive and Respiratory Syndrome Virus

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

Researchers at Kansas State University (Olivia Harrison, Catherine Grace Elijah, Allison K. Blomme, Haley Ottot, Jianfa Bai, Elizabeth Poulsen-Porter, Jason C. Woodworth, Chad B. Paulk, Jordan T. Gebhardt, and Cassandra K. Jones) share their finding the efficacy of boot baths for control of the spread of porcine viruses.

Modeling between-farm transmission dynamics of porcine epidemic diarrhea virus: characterizing the dominant transmission routes

Read about PEDV dissemination modeling in today’s Science Page, presented by Jason A. Galvis, Cesar A. Corzo, Joaquín M. Prada, and Gustavo Machado.

PEDV Detection in Manure Pits Confirmed 841 to 1,949 days after Disease Outbreaks

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

Today, Dr. Allison and collaborators from Iowa State University and Central Life Science are sharing results regarding the detection of PEDV in manure pits for extended periods after disease outbreaks.

Key points:

Determining the origin of a PEDV re-infection at a farm is often difficult or inconclusive.
Manure pits have been shown to harbor virus after a farm has transitioned to a negative status.
PEDV DNA was found in farm manure pits between 46 and 1,949 days post disease outbreak.

Forecasting PEDv in the US through the use of machine learning

This week, Dr. Kim VanderWaal and her team share an update on a highly anticipated project regarding the forecast of PEDv in the United States.

Science Page: Stability of Porcine Epidemic Diarrhea Virus on Fomite Materials at Different Temperatures

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This week, we are sharing the summary of Dr. Cheeran’s team study on the stability of PEDv on fomite materials at different temperatures.

Key points:

Type of material and temperature have an impact on PEDV stability.
Infectious PEDV was not recovered from any fomite material after 2 days at room temperature (25ºC / 77ºF).
PEDV showed higher stability on plastic, cloth, Tyvek® coveralls, aluminum foil, Styrofoam at 4ºC (39.2ºF).
Virus could be detected by qRT-PCR from contaminated fomites even when infectivity was not observed.
