“Coughs sound different because of subtle differences in the ways that organisms cause damage to the respiratory tract”

Pigs with PRRS have a distinctive cough due to the type of damage inflicted by the virus, we hear from Dr. Greg Stevenson (veterinary diagnostic pathologist at Iowa State University, USA). Combined with information on the number of pigs in a barn that develop coughing over time, this helps us to recognise PRRS and differentiate it from other respiratory pathogens.
