Abstract

The goal of this work was to investigate the type and etiology of bacterial porcine pneumonia by analyses of autopsy findings made in the Tierärztlichen Ambulanz Schwarzenbek, Aussenstelle der Freien Universität Berlin, and in the Institut für Tiergesundheit, Milchhygiene und Lebensmittelqualität der Landwirtschaftskammer Westfalen-Lippe in Münster in the years from 1991 to 1993. The evaluation of the results of the total 6560 autopsies (N = 6560) of pigs shows: 1. Pneumonia as the main diagnosis was found in 24.4% (n = 1599), as the second diagnosis in 14.3% (n = 941) of the sections. 2. Fattening pigs show signs of pneumonia (43.2% (n = 1096) vs. 27.8% (n = 706); N = 2540) more frequently than younger pigs. 3. The most frequently isolated etiologic agents from lung specimens (N = 2337) were Pasteurella multocida (49.3%; n = 1152), Actinobacillus pleuropneumoniae (5.4%; n = 125) and Bordetella bronchiseptica (5.3%; n = 124). 4. With increasing age of the isolation rate of Pasteurella multocida (piglets [N = 210]: 21.4%, n = 45; fattening pigs [N = 652]: 61.8%, n = 403) and Actinobacillus pleuropneumoniae (piglets: 1.4%, n = 3; fattening pigs: 7.1%, n = 46) increased while Bordetella bronchiseptica (piglets: 10.0%, n = 21; fatt...Continue Reading
