[Detection of Haemophilus parasuis and Mycoplasma hyorhinis in swine and association of those pathogens with clinical and pathological-anatomic findings]. / Nachweis von Haemophilus parasuis und Mycoplasma hyorhinis bei Schweinen sowie Assoziation dieser Erreger mit klinischen und pathologisch-anatomischen Befunden.

In routine diagnostic it is difficult to detect a Haemophilus parasuis infection causing a polyserositis. In the presented study, a detection method by means of PCR, from collective swabs of the serosal surfaces from animals, with and without fibrinous serositis, was investigated. A significant association was detected between post mortal findings of fibrinous serositis and molecular biological detection of Haemophilus parasuis and Mycoplasma hyorhinis. However, no significant association existed between cultural detection of Haemophilus parasuis in bronchoalveolar lavage fluid and pathological-anatomical ascertainable fibrinous serositis. A significant association between Haemophilus parasuis and Mycoplasma hyorhinis could be determined in the animals that were included in this study.
