Despite the many advances throughout the years, influenza still cannot be fully controlled and represents a major economic threat to the swine industry. Therefore, we can never discuss it enough and it’s never too late to tackle this challenge. In this podcast host Laura Greiner and guests Dr. Jeremy Pittman and Dr. Marie Culhane have a roundtable conversation about the latest updates about influenza, diagnostics and surveillance, and key strategies to manage those.Continue reading “Influenza in swine: the latest updates – A podcast episode”
Dr. Vilalta and collaborators from the University of Minnesota provide new insights for the potential use that processing fluid (PF) may have to detect M. hyopneumoniae in breeding farms by bringing us a clinical case published in VetRecord Case Reports.
- Genetic material of Mycoplasma hyopneumoniae from PF was quantified by real-time PCR.
- The origin of M. hyopneumoniae genetic material detected in PF needs to be clarified.
- Processing fluids are a potential sample to detect M. hyopneumoniae in breeding herds.
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, Shaoyuan Tan, PhD-candidate from the Murtaugh’s lab is sharing the technology behind MinION.
- MinION sequencing can be used for antibiotic resistance prediction to guide prudent and effective antibiotic use
- MinION sequencing can improve clinical diagnosis to strain-level detection
- MinION sequencing is a potential solution for rapid emerging infectious disease investigations
M. hyopneumoniae causes one of the swine industry’s most devastating diseases—a chronic, infectious pneumonia that can cause respiratory distress and lung lesions in pigs. It can also severely slow pig growth. In order for producers and veterinarians to best measure the success of their disease control and elimination efforts, they need to be able to detect the pathogen in live pigs. However, many diagnostic tools can be unreliable. Dr. Maria Pieters’ lab at the University of Minnesota College of Veterinary Medicine recently led a study to decipher the reliability of two tools, laryngeal swabs and deep tracheal catheters, in detecting the pathogen.Continue reading “What are the best diagnostic tools for tracking Mycoplasma hyopneumoniae in swine?”
This week, we are sharing a report by Harmon et al. from Iowa State University regarding PCR clamping. This project was funded by AAVLD Thermo Fisher Innovation Grant in Veterinary Diagnostic Medicine and ISU-VDL.
- Conventional ORF5 sequencing may not differentiate between wild-type or vaccine-like.
- Blocking the amplification of vaccine-like sequences it is possible to increase the likelihood of wild-type amplification.
- Clamping allows the amplification of the wild-type with mixtures containing as little as 10% of a mixture with the vaccine-like.
