More accurate gilt testing needed to detect Mycoplasma hyopneumoniae

Alyssa Betlach -DVM, veterinarian with Swine Vet Center and graduate student at the University of Minnesota- talks in Pig Health Today® about differences in the ability to detect Mycoplasma hyopneumoniae based on sample types.

Highlights

  • Transmission of M. hyopneumoniae is very slow compared to other pathogens. Gilts and sows have a critical role in the transmission of M. hyopneumoniae
  • Accurate gilt surveillance is key in those sow herds seeking negative M. hyopneumoniae status.
  • To detect M. hyopneumoniae, the laryngeal swabs and deep tracheal catheters are more accurate than other sample types during the early stage of infection.

What are the best diagnostic tools for tracking Mycoplasma hyopneumoniae in swine?

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.
