processing fluids – Swine in Minnesota

PRRS monitoring by processing fluids in Italian swine breeding farms

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.

In this week’s Science Page, researchers Matteo Tonni, Claudia Romeo, Nicoletta Formenti, M. Beatrice Boniotti, Flavia Guarneri, Livio Colosio, Simone Andreoni, Federico Scali, Paolo Pasquali and G. Loris Alborali share their findings from monitoring Italian breeding herds.

What is the role of parity in the detection of PRRSV in processing fluids?

Today we are sharing a paper by former MSHMP team member Juan Sanhueza, in collaboration with Drs. Cesar Corzo, Mariana Kikuti, and Declan Schroeder from the UMN swine group and multiple Midwestern swine systems. This recent publication in Preventive Veterinary Medicine looks at the impact of sow parity on the detection of PRRS virus in processing fluids.

Porcine reproductive and respiratory syndrome prevalence and processing fluids use for diagnosis in United States breeding herds

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.

In this Science Page we look at research conducted by Mariana Kikuti, Carles Vilalta, Juan Sanhueza, Claudio Marcello Melini, and Cesar Corzo from the MSHMP team. They look at PRRS prevalence and how the use of processing fluids can help diagnose the disease.

Litter level agreement of PRRS PCR results in testicles, tails and udder wipes samples

This recent publication by former MSHMP post-doc Dr. Carles Vilalta compares various sample types used to assess PRRS status of piglets at the litter level. The paper is available in the Preventive Veterinary Medicine journal.

Senecavirus A in processing fluids during an outbreak of SVA – a call for study participation!

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.

Doctors Guilherme Preis and Cesar Corzo from the University of Minnesota share with us preliminary data from a Senecavirus A (SVA) outbreak investigation in a sow herd. This research emphasizes the importance of understanding the within-herd epidemiology of this virus.

Highlights

SVA is still present in the U.S. swine herds at lower levels.
SVA RNA has been consistently detected in processing fluids in the event of a disease outbreak in a sow herd.
Viral dynamics and shedding cessation in the breeding herds need to be better characterized.
