[Examination of primary SPF swine after experimental infection with Haemophilus parasuis. Clinical symptoms, changes in hematological parameters and in the parameters of the cerebrospinal fluid]

The objectives of this work were to cause the Glässer's disease (GD) in primary specific pathogen free piglets after experimental infection, to observe the clinical symptoms and to examine the influence of the infection on the haematological parameters. GD was caused by experimental infection of Haemophilus parasuis in seven to eight weeks old specific pathogen free piglets. In relation to the infection route the morbidity was high (83-100%) and 20% of the infected piglets died. Based on the physical examination fever, respiratory distress, cramps and paralysis were observed which are typical for GD. Arthritis and nerval symptoms are also typical but less common in Glässer's disease. PCV was significantly decreased and WBC significant increased before the piglets were euthanatized.
