In this recent publication in the Canadian Journal of Veterinary Research, Dr. Alyssa Betlach from the MycoLab at the University of Minnesota investigates the genetic variability of Mycoplasma hyopneumoniae within and across various production flows within a single system.
Key points
- Multiple-locus variable-number tandem repeat analysis allows to detect genetic variability between M. hyopneumoniae strains.
- Four production flows were sampled over a duration ranging from 4 months to 3 years.
- Between 1 and 6 variable-number tandem repeat (VNTR) types were found within the four production flows.
- VNTR types in growing sites seem to originate from their respective breeding herds.
