I feel that the ones I took with a digital camera are fairly typical, so I'll share them with everyone for reference... Attachments: You need to log in to download or view attachments. No account? Register

I support you, and at the same time I'd like to remind you that it would be even better if you could adjust the image colors a bit. Thanks

I want to say sorry to the original poster, but I must speak up: this is very, very likely not contagious pleuropneumonia. Even if it is, it is not typical. Contagious pleuropneumonia is a hemorrhagic pleuropneumonia caused by Actinobacillus pleuropneumoniae. The pathogenic mechanism of Actinobacillus pleuropneumoniae is that the toxins it secretes cause tissue necrosis, including necrosis of blood vessels, resulting in the pulmonary hemorrhage, necrosis, and fibrinous exudation seen on gross necropsy. These lesions originate in the lungs. When severe enough, the lung tissue near the pleura also undergoes necrosis, and then the necrotic material enters the thoracic cavity, which is what causes pleuritis. There is also a very important feature: unlike ordinary bacterial pneumonia, the lesions caused by Actinobacillus pleuropneumoniae often appear on the dorsal side of the diaphragmatic lobe of the lung (that is, the rearmost and largest lung lobe). This is considered a very important supporting diagnostic sign. The case uploaded by the original poster does indeed have pleuritis, with extensive multifocal adhesions between the lungs and the costal pleura visible. However, the lungs do not show typical necrotizing hemorrhagic lesions, and judging from these images, the lung lesions also do not show a very typical distribution of Actinobacillus pleuropneumoniae lesions. For this case, it should be bacterial septicemia (with Streptococcus and Haemophilus parasuis being highly likely) causing increased vascular permeability, after which exudate with relatively high protein content in the thoracic cavity causes pleuritis, leading to the adhesions seen on necropsy. The lungs in this case may also have pneumonia (it is unclear, possibly only congestion), but having both pneumonia and pleuritis does not mean it is Actinobacillus pleuropneumoniae. This is because the primary site of this pleuritis is actually the thoracic cavity, whereas the primary site of Actinobacillus pleuropneumoniae is the lungs. Still, thank you to the original poster for uploading the images. I hope everyone can learn something from this case.

If there is laboratory diagnosis as a basis, then it would be relatively clear. Necropsy can only determine the general direction; necropsy cannot definitively diagnose whether this is APP or HPS disease.[ This post was last edited by syz on 2007-6-2 08:47 ]

These pleural adhesions are truly classic.....

What was uploaded above is precisely the relatively typical lesions of contagious pleuropneumonia. Of course, gross necropsy alone cannot confirm a diagnosis. But as veterinarians, we must know these relatively specific lesions. When you necropsy a pig, you need to know which diseases should be considered first, which should be considered secondarily, or which can basically be disregarded, and that is where the value of necropsy lies.

Thanks! Brother above, I learned another classic point.

Worth studying carefully!
