Pathogenesis of Haemophilus parasuis Infection: Update of Current Research
Haemophilus parasuis has traditionally been considered a sporadic stress associated disease of young swine in conventional herds.12 In recent years there has been renewed interest in H. parasuis infection for several reasons. One of these reasons has been the expansion of high health status herds in which H. parasuis can produce severe disease with high morbidity and mortality in all age groups. 7 Another important factor is the emergence of Porcine Reproductive and Respiratory Syndrome Virus in Europe and North America as H. parasuis can be an important second~ bacterial infection in herds infected with PRRSV. 0 The following will provide a brief review of the role H. parasuis plays in swine disease and an update on current research efforts relating to the pathogenesis of H. parasuis infection.
