Lung from a suckling piglet. Craneo-ventral fibrinous bronchopneumonia (pleuropneumonia) in suckling piglets is generally associated with Bordetella bronchiseptica infection. Haemophilus parasuis usually produces pleuritis but no bronchopneumonia at different ages. In contrast, Actinobacillus pleuropneumoniae (App) causes fibrinous-necrotizing-hemorrhagic lesions in the lungs of growing and finishing pigs, but not in suckling piglets. Moreover, lesions associated to App are usually located caudo-dorsally in the lung.
