Improving M. hyopneumoniae diagnostic capabilities by harnessing the infection dynamics

In this concise and straight-forward review for The Veterinary journal, Dr. Garcia-Morante in collaboration with the MycoLab at the UMN shares the latest knowledge around Mycoplasma hyopneumoniae infection and what the best practices for diagnosis are. The full article is available on the journal’s website.

Highlights

  • This review updates M. hyopneumoniae infection diagnosis and dynamics.
  • Understanding M. hyopneumoniae infection dynamics is critical for diagnosis.
  • Final diagnosis is based on clinical observations aligned with laboratory results.
  • Laboratory tests are useful for detection of asymptomatic carriers.

Summary: The impacts of viral infection and subsequent antimicrobials on the microbiome-resistome of growing pigs

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.

The Science Page this week describes a study done by Tara N. Gaire, Carissa Odland, Bingzhou Zhang, Tui Ray, Enrique Doster, Joel Nerem, Scott Dee, Peter Davies and Noelle Noyes and sheds some light on the antimicrobial resistances carried by the pig’s microbiome after disease and treatment.

Evidence of influenza A infection and risk of transmission between pigs and farmworkers

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 today’s Science Page, University of Minnesota researchers Gustavo Lopez-Moreno, Peter Davies, My Yang, Marie Culhane, Cesar A. Corzo, Chong Li, Aaron Rendahl and Montserrat Torremorell present research on interspecies transmission of influenza A between pigs and farmworkers.

Multiple vaccinations: what effect on M. hyopneumoniae infection?

Dr. Betlach and the team from the MycoLab recently published a study in the journal Vaccine, regarding the impact of multiple vaccines against Mycoplasma hyopneumoniae. They assessed bacterial load and protection against infection in gilts.

Highlights

  • Vaccination against M. hyopneumoniae reduced bacterial load in infected gilts.
  • Vaccination of both infected and contact gilts reduced M. hyopneumoniae transmission.
  • Genetic diversity of M. hyopneumoniae was not influenced by vaccination.

Best of Leman 2018 series #3: J.Angulo – Understanding PRRSV infection dynamics in growing pigs in control and elimination programs

We launched a new series on the blog last year. Once a month, we are sharing with you a presentation given at the Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

We can find all of the presentations selected from last year’s conference on the blog here.

Our third presentation for this year is from Dr. Jose Angulo from Zoetis and Dr. Paul Yeske from Swine Vet Center regarding PRRS infection dynamics in growing pigs.
