Survival analysis of two Mycoplasma hyopneumoniae eradication methods

In this new article published in the Preventative Veterinary Medicine journal, Dr. Paul Yeske from Swine Vet Center in collaboration with Dr. Maria Pieters from the University of Minnesota share a survival analysis of two different eradication methods for Mycoplasma hyopneumoniae in farrow-to-wean farms.

Streptococcus equi subsp. zooepidemicus associated with sudden death of swine in North America

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. Matheus Costa from the University of Minnesota in collaboration with Dr. Brad Lage from Maple Leaf Agri-Farms share a case of sudden death due to Streptococcus equi subsp. zooepidemicus.

Key Points

  • Historically described as a commensal of the swine upper-respiratory tract, Streptococcus equi subsp. zooepidemicus was only reported previously in Asia as an important swine pathogen. 
  • Here we report the isolation and whole genome characterization of Streptococcus equi subsp. zooepidemicus associated with a sudden death outbreak in pigs in North America.

Creating measurable, practice-relevant day-1 competencies for swine veterinary education

In this open-access publication in the Education in the Health Professions journal, Dr. Perle Zhitnitskiy and faculty from the University of Minnesota describe their process to create day-1 competencies for veterinary graduates interested in swine practice.

Key points

  • The University of Minnesota collaborated with swine practitioners, faculty from other Universities and the American Association of Swine Veterinarians to develop relevant day-1 competencies.
  • Three levels of expertise were defined: basic, intermediate and defined.
  • 109 competencies were developed in nine domains: pig handling, swine husbandry, sample collection, record keeping, treatment and prevention, biosecurity, communication and regulatory.

Use of Whole Genome Sequencing during a PRRSv outbreak investigation

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.

We hope our US readers had a great Thanksgiving surrounded by loved ones. We are grateful that all of you keep reading us week after week and we hope we can continue providing you with valuable content for a long time!

This week, Drs. Sunil Mor and Albert Rovira from the University of Minnesota Veterinary Diagnostic Laboratory explain how we can use whole genome sequencing during a PRRS outbreak investigation.

Key Points

  • Viral recombination is documented in PRRSv
  • Whole Genome Sequencing can provide the detailed information to better understand recombination and PRRSv dynamics

Detection of Mycoplasma hyorhinis and Mycoplasma hyosynoviae in oral fluids and correlation with pig lameness scores

In this newly released article from the MycoLab in the Veterinary Microbiology journal, Dr. David Pillman working with Dr. Maria Pieters shares his results regarding detection of two mycoplasma species and how this was correlated with lameness scores in nursery and finishing pigs.

Key points

  • M. hyorhinis was frequently detected in oral fluids in nursery and finisher herds
  • High detection of M. hyosynoviae in oral fluids was observed in finisher herds.
  • Proportion of lame pigs and M. hyosynoviae detection in oral fluids were correlated.
