Pinpointing pathogens, dead or alive: CVM graduate student designing better way to manage respiratory disease in swine

Mycoplasmal pneumonia of swine (MPS) first appeared in pigs a century ago, when producers had a hunch that it wasn’t influenza that was taking their droves. Today, the disease is nearly endemic.

“It exists in just about any country where pigs are raised,” says Maria Pieters, DVM, PhD, director of the College of Veterinary Medicine’s (CVM) Swine Disease Eradication Center. 

When the minuscule bacteria, called Mycoplasma hyopneumoniae, first enter a pig’s lungs, it can easily go undetected. But as the pig approaches the finishing stage, the bacteria cripples its respiratory system and stunts the swine’s growth. The infected pig takes longer to reach market size, elevating costs for producers. They also suffer, something veterinarians strive to eliminate. 

There’s a better way to manage the spread of the disease, and Albert Canturri, a PhD candidate in CVM, is designing it.

Happy Holidays!

This Friday, we are taking a break from our regular Science Pages to wish you all Happy Holidays. We are thankful for the time you spend reading our blog and for your support, that allows us to continue sharing our work. We hope that you have a joyful and peaceful time with your loved ones and we will be back on Tuesday as per usual.

Best of Leman 2021: Dr. Gerdts – New approaches to swine vaccines

This is our most popular series on the blog. 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.

You can find all of the presentations selected from previous conferences on the blog here.

This month, we are sharing one of the keynotes of the 2021 conference: Dr. Volker Gerdts takes us on a journey into the future of swine vaccines and vaccination strategies.

Evaluating the uses of geofencing under field conditions

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 sharing an update from Dr. Andreia Arruda’s lab at the Ohio State University.

Key Points

  • The vertically integrated structure of swine production and the network among swine facilities allow important swine pathogens to spread within and between production sites.
  • This study assessed the use of a geofencing technology to monitor personnel movements within multisite production systems.
  • Social network analysis indicated that employees in administrative and technical support roles are an important consideration with respect to increasing indirect connections between sites of different production phases.

Modelling PRRSV dissemination dynamics to quantify the contribution of multiple modes of transmission

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 Machado’s team from North Carolina State University shares the results of their latest modelling PRRS transmission project.
