Report on the First African Swine Fever Case found in Greece in 2020

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 presenting a report by Bellou et al., from the Aristotle University of Thessaloniki, Greece on the first case of African Swine Fever discovered back in 2020.

Main Points

In February 2020 the first African Swine Fever (ASF) case in Greece was diagnosed in a backyard swine farm.
Clinical symptoms were vague and necropsy findings could be attributed to other conditions, including ASF.
In areas neighboring high ASF-risk areas, ASF should always be included on the differential diagnosis, even in cases with mild symptoms, due to the high mortality rate and acute spread that ASF poses.

Pooling udder skin wipes to detect influenza in preweaning pigs

This is a recent publication from the Torremorell’s lab refining the use of udder wipes to detect influenza in preweaning pigs. It is available in the Journal of Veterinary Diagnostic Investigation.

Key points

Pooling of three, five, and ten udder wipes was evaluated.
Sensitivity decreased if the Ct count was above 31.5.
Pooling more than three udder wipes can affect the ability to detect influenza virus.
