Ability of different matrices to transmit African swine fever 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.

This week, the MSHMP team summarized a report from the European Food Safety Authority (EFSA) regarding African Swine Fever transmission through fomites.

Assessing Senecavirus A shedding and transmission in growing pig populations

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, Drs. Preis and Corzo are inviting you to participate in an AASV-funded project regarding the epidemiology of Senecavirus A in growing pigs.

Are mosquitoes a risk for ASF?

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, the MSHMP tip summarized a publication by Qin et al. regarding the risk of mosquitoes carrying and transmitting African Swine Fever virus.

Key Points

African swine fever (ASF) continues to pose a large risk in the absence of safe and effective ASF vaccines
There is evidence indicating that mosquitos may be a possible ASF vector
Mosquitos captured at ASF positive farms had DNA extracted and tested for ASF with no positive results

Modeling the transmission and vaccination strategy for PRRS 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.

This week, the Science Page is written by Dr. Galvis et al. from the Machado lab at North Carolina State University. They report their results with modeling PRRSv transmission in situations where vaccines can be used as mitigation tools.

Transmission of a live influenza A virus vaccine in commercial pre-weaned pigs

The Plos One journal just published a new study by Dr. Gustavo Lopez and the Torremorell lab. The objectives of the project were to 1)assess the onset and duration of live attenuated influenza vaccine shedding in vaccinated pre-weaned pigs, 2)investigate the transmission of the live attenuated influenza vaccine from vaccinated to non-vaccinated pigs under field conditions and 3)evaluate whether the live attenuated influenza vaccine could be aerosolized and detected in the environment.
