M. hyo intensifies respiratory disease

Mycoplasma hyopneumoniae (M. hyo) is the primary initiator of enzootic pneumonia – a widespread and chronic disease in swine herds. M. hyo is also a common agent implicated in the development of Porcine Respiratory Disease Complex (PRDC).

Because M. hyo damages the cilia in the lower respiratory tract, secondary viral and bacterial pathogens can more easily invade and infect the pig. For example, it increases the likelihood of disease caused by viral infections, such as PCV2. The synergistic impact of immunosuppression and co-infection results in not only disease, but also a significant reduction in average daily weight gain (ADWG) in growing pigs.
