Dr. Maria Pieters, head of the MycoLab at the University of Minnesota has edited, in collaboration with Drs. Dominiek Maes and Marina Sibila, a newly published book on swine Mycoplasmas. Mycoplasmas in Swine provides up-to-date scientific, clinical and practical information useful to scientists and veterinarians alike. Most emphasis has been placed on Mycoplasma hyopneumoniae, as this is economically the most important Mycoplasma sp. in swine. However, other pathogenic species like Mycoplasma hyorhinis, Mycoplasma hyosynoviae and Mycoplasma suis are discussed.Continue reading “Mycoplasmas in swine: a new comprehensive book”
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.
- 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.
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.
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
