PRRSV is endemic in most pig producing countries of the world and causes disease characterized by abortions and stillbirth,increased pre-weaning mortality and respiratory disorders in growing pigs.The genotype 1 strains of PRRSV are primary pathogens for reproductive failure and abortion.However,infections with this EU-type of PRRSV,only,do not lead to respiratory disease,but can induce a change in lung immune cell composition.In recent experiments we have been able to show,that the experimental infection had an effect on cellular immunity parameters and also induced mild,interstitial,inflammatory lung alterations,which can be predisposing for pneumonia.
