Zoetis Releases Update of M. Hyo Manual

2 October 2020, at 5:11pm

Zoetis has released an update of the comprehensive manual, “A Contemporary Review of Mycoplasma Hyopneumoniae Control Strategies,” a 62-page booklet with 14 articles developed by swine-disease experts specializing in this pathogen.

The revised booklet features an updated section on breeding-herd classifications and an entirely new section on fogging for controlled exposure to Mycoplasma hyopneumoniae (M. hyo).

Also known as enzootic pneumonia, mycoplasma pneumonia is a prevalent and costly disease caused by Mycoplasma hyopneumoniae (M. hyo). In damaging the cilia (tiny hairs lining pigs’ upper respiratory airways), the disease exposes the respiratory tract to bacterial and viral infections and coinfections by other pathogens.

“Respiratory infection caused by M. hyo has been a well-known feature of swine production for decades,” said Lucina Galina Pantoja, DVM, PhD, director, U.S. Pork Technical Services, Zoetis. “Despite a long acquaintance with M. hyo and its principal clinical manifestation, enzootic pneumonia (EP), some gaps in our understanding of the disease and its control still remain, and new information on diagnosis and management of M. hyo infection has emerged.”

“The purpose of this review is to provide a comprehensive update on M. hyo,” she added.

The manual is structured as a five-step approach for managing M. hyo in the production setting, including:

  1. Establishing herd status classification criteria for breeding herds
  2. Diagnosis of infection
  3. Risk management
  4. Control measures
  5. Monitoring intervention strategies

“Regardless of a farm’s M. hyo status, there are chapters in this manual that will be beneficial for production veterinarians,” Galina noted.
