Mycoplasma hyopneumoniae variability highlights the need for new terminology

In this latest article published in Transboundary and Emerging Diseases, Dr. Alyssa Betlach, phD candidate in Dr. Maria Pieters lab, reviews the observed variability in Mycoplasma hyopneumoniae, the effect it can have in swine farms and how a better terminology is possible to improve scientific communication.

Comparison of individual, group and environmental sampling strategies to conduct influenza surveillance in pigs

In this new scientific publication from Dr. Jorge Garrido, PhD candidate from the Torremorell lab, numerous sampling strategies to monitor influenza were compared. the following individual, litter, and environmental samples were included in the study:

  • Nasal swabs
  • Nasal wipes
  • Oropharyngeal swabs
  • Oral fluids
  • Surface wipes
  • Udder wipes
  • Airborne particle deposition
  • Air

Effect of strain-specific maternally-derived antibodies on influenza A virus infection dynamics in nursery pigs

A new scientific article from the Torremorell lab, about the influence of maternal antibodies on influenza dynamics was published in PLoS ONE.

The study followed 10 cohorts of nursery piglets form a single influenza-positive sow farm and compared influenza dynamics based on the vaccination status of the dam.

Mycoplasma hyorhinis and Mycoplasma hyosynoviae dual detection patterns in dams and piglets

Today, we are sharing an original research article published by the MycoLab and Dr. Maria Pieters in PLOS One regarding detection patterns for 2 species of mycoplasmas in sows and piglets.

The objectives of this study were to:

  • describe when Mycoplasma hyorhinis and Mycoplasma hyosynoviae can be detected in piglets and is sows,
  • assess if there was a correlation between detection of the mycoplasmas in the sow and in the piglet, and
  • assess if there was a correlation between lameness and mycoplasma detection.

Conclusions

Under the conditions of this investigation, dams appeared to be consistently positive for both M. hyorhinis and M. hyosynoviae prior to weaning.

In contrast, higher detection was observed in piglets at week 3, in comparison to week 1 post-farrowing, with M. hyorhinis, while detection of M. hyosynoviae was remarkably minimal.

The relative risk of developing lameness in postweaning piglets was highly associated with the detection of M. hyorhinis at 3 weeks of age

This research article is available in open-access on the PlOS One website.
