[Contribution to the experimental hemophilus infection (Haemophilus parahaemolyticus, Haemophilus parasuis) in SPF piglets. 2. Comparative pathology and histology].
The pathologico-anatomic and even more the histological pattern of experimental Haemophilus parahaemolyticus pleuropneumonia in specific-pathogen-free piglets was found to be characteristic in the peracute, acute, and subacute-chronic stages of the disease. It is an infection which can be morphologically differentiated from other forms of pneumonia in swine primarily by three factors, localisation of the changes, inflammation, and a typical cell response. Changes following experimental Haemophilus parasuis infection were found to occur irregularly on serous skins and, in continuation, in the lung and joints. These were not characteristic and failed to exhibit morphological peculiarities.
