Conteúdo: | In a population of 700 goats, 150 died; of these, 29 were necropside. Ten of the 29 goats had pleuropneumonia. Mycoplasmma mycoides subsp. mycoides (Large Colony) (MmmLC), Mycoplasma mycoides subsp. capri (Mmc), and Pasteurella multocida were isolated from five of the pleuropneumonic goats. Gross and microscopical lesions were typical of caprine pleuropneumonia (CPP), with bronchopneumonia, fibrinopurulent or fibrinonecropic pleuropneumonia and dilatation of the interlobular septa and pleura. Immunohistochemical examination with antisera against MmmLC and Mmc showed mycoplasma antigens in all 10 goats with CPP. In all cases, both MmmLC and Mmc antigens were detected together. Mycoplasma antigens were present in the lumina of the airways and alveoli, mainly inside the cytoplasm of netrophils and macrophages, but extracellular antigen was demonstrated in areas of necrosis. Pasteurella antigens were detecd in four of the 10 animals with CPP. From the histological, immunohistochemical and microbiological results it was conluded that the two mycoplasmas, acting together, caused the pleuropneumonia, with P. multocida playing a subsidiary synergistc role.
