Dr. David Ley, Professor, Department of Population Health and Pathobiology in the College of Veterinary Medicine, North Carolina State University recently presented an update of Mycoplasma research and molecular epidemiology to an avian health advisory panel convened by the North Carolina Department of Agriculture and Consumer affairs.

The slide set prepared by Dr. Ley is reproduced with his kind permission for the benefit of subscribers to The important issues which emerged from the presentation were:-

  • Mycoplasma species are extremely specialized organisms and do not survive for more than 2 to 3 days in the environment in the absence of living host, which obviously facilitates decontamination.
  • Under commercial conditions the pathogenic species are most frequently transmitted by the horizontal route through movement of personnel and equipment which presumes that effective biosecurity should prevent introduction of infection.
  • Non-commercial poultry populations serve as reservoirs of Mycoplasma infection
  • Advanced diagnostic techniques are now available including RT-PCR and RAPD fingerprinting to differentiate among field strains of MG
