1-7-4 – Swine in Minnesota

Tracking between-farm PRRSV-2 transmission and its potential routes through the virus genetic relationship and farm-based data

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 University of Minnesota researchers Nakarin Pamornchainavakul, Dennis N. Makau, Igor A. D. Paploski, Cesar A. Corzo and Kimberly VanderWaal take a look at the spread of different variants of PRRS between farms.

Do all PRRSV variants have the same level of infectivity?

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.

University of Minnesota researchers Marcello Melini, Mariana Kikuti, Montse Torremorell, Kimberly VanderWaal, Stephanie Rossow, Jerry Torrison, and Cesar Corzo share the results of a study conducted to measure the infectivity of different PRRSV variants.

Detection of PRRSV RFLP type 1-7-4 over time

This week, Dr. Mariana Kikuti from the MSHMP team shares information about the PRRS RFLP type 1-7-4 prevalence in the MSHMP data.

Key Points

PRRSV RFLP type 1-7-4 was first identified in our MSHMP dataset in 2003.
An increasing trend up to 2014 has been observed and is now on a decreasing trend.
