Mycoplasma

Mycoplasma Research at the UMN (Areas of research focus, accomplishments and highlights)

Diagnostics

• Early detection of Mycoplasma hyopneumoniae:
     o Comparison of current methods
     o Development of new assays
• Development of an isothermal amplification method for detection of Mycoplasma hyopneumoniae
• Improving the serological detection of swine Mycoplasmas
• Development and validation of a quantitative PCR for the detection of Mycoplasma hyorhinis in clinical samples
• Development of a molecular based typing method for Mycoplasma hyorhinis

Immunology

• Neonatal immune response to Mycoplasma hyopneumoniae infection and/or vaccination
• Effect of extended lactation on piglet immune response

Epidemiology and Control

• Investigating the genetic variability of Mycoplasma hyopneumoniae strains circulating in US herds
• Assessment of duration of Mycoplasma hyopneumoniae infection in infected populations
• Investigating factors affecting Mycoplasma hyopneumoniae persistence and transmission during the chronic phase of infection
• Evaluation of Mycoplasma hyopneumoniae transmission from asymptomatic carriers to unvaccinated and vaccinated pigs
• Managing gilt introduction to Mycoplasma hyopneumoniae positive herds
• Effect of sow and piglet medication on piglet colonization with Mycoplasma hyopneumoniae
• Characterization of Mycoplasma hyorhinis transmission and spread within endemically infected populations
