December 2020 – Swine in Minnesota

China Swine Industry Confident Following COVID-19

Happy holidays! We hope you have a special season and enjoy good times with your loved ones and maybe a couple of podcasts! Here is our latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

Today’s podcast looks at how China’s ability to reduce the incidence of COVID-19 has given their commercial swine industry the confidence to expand.

Contemporary North American Mycoplasma hyopneumoniae MICs

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 MycoLab at the University of Minnesota shares results from a project looking at Mycoplasma hyopneumoniae Minimum Inhibitory Concentrations (MICs) from various US isolates.

Key points

Antibiotic susceptibility profiles of eleven M. hyopneumoniae isolates circulating in the US within the most recent six years were obtained.
Overall, a high in vitro efficacy of the tested antimicrobials against M. hyopneumoniae field isolates was observed.

Mycoplasmas in swine: a new comprehensive book

Dr. Maria Pieters, head of the MycoLab at the University of Minnesota has edited, in collaboration with Drs. Dominiek Maes and Marina Sibila, a newly published book on swine Mycoplasmas. Mycoplasmas in Swine provides up-to-date scientific, clinical and practical information useful to scientists and veterinarians alike. Most emphasis has been placed on Mycoplasma hyopneumoniae, as this is economically the most important Mycoplasma sp. in swine. However, other pathogenic species like Mycoplasma hyorhinis, Mycoplasma hyosynoviae and Mycoplasma suis are discussed.

ASF and PED alter China swine production: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

‘At The Meeting’ Honoring Dr. Bob Morrison focuses on how African Swine Fever (ASF) and Porcine Epidemic Diarrhea virus (PEDv) have driven changes in farm design and biosecurity in China, allowing China’s swine industry to regain an estimated 80 percent of its swine herd.

Which wipes are better to detect flu: udder skin or nasal wipes?

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, Dr. Albert Canturri from the Torremorell lab is sharing results on a study looking at udder skin wipes and piglet nasal wipe to detect swine influenza.

Key points

Various wipe types can be used to sample IAV from the udder skin of lactating sows. Although differences between wipe types were not seen, wipes that were wet provided a better detection rate than dry wipes.
Furthermore, wiping the nose of 5 piglets within a litter resulted in higher litter detection rates than sampling the udder directly. This indicates that within litter prevalence is a driver for IAV detection using wipes.
Future steps are needed to assess differences in virus isolation among sampling procedures.
