This experiment was performed to study gross and microscopic lung lesions after endotracheal inoculation with Actinobacillus pleuropneumoniae (A. pleuropneumoniae) serotype 1 in twenty-four guinea pigs.

The differences between the pulmonary lesions were evaluated. In this experiment, the lesions of peracute infection by A. pleuropneumoniae were induced within 4-6 hours and the lesions of subacute infection, characterized by fibrinopurulent pleuritis were observed in surviving animals 18-20 hours post inoculation. The results suggested that guinea pigs could be used …
