title: [Clinical and laboratory diagnostic findings in chronic pleuropneumonia of swine].
abstract: In the course of an experimental study 12 pigs were infected intrabronchially with the pathogen of infectious porcine pleuropneumonia, Actinobacillus pleuropneumoniae. All animals survived the acute stage of infection due to the application of subtherapeutic doses of antibiotics. After infection all of the animals showed clinical signs of acute pneumonia with an elevation of body temperature to about 41 degrees C. Bronchoalveolar lavage fluid (BALF) was taken every week endoscopically. An increase of neutrophil granulocytes could be observed at day 7 and 14 after infection. In parallel, a clear granulocytosis and a shift to the left of the nuclei was observed at day 7. Comparing the methods for detection of Actinobacillus pleuropneumoniae serological assays like the complement-fixation assay (CFA) and enzyme-linked immunosorbent assay (ELISA) as well as immunofluorescence in lung tissue and BALF were more sensitive than cultural isolation from lung tissue, tonsils and BALF.
