Animal | Route | Lung Lobes | Peripheral Lymph Nodes1 | Bowel | Spleen | Heart | Other |
---|---|---|---|---|---|---|---|
08204 | IT | Extensive congestion, hyperemic, with multifocal areas of consolidation.Tracheal mucosa congested and edematous | Minimally congested & edematous | Diffusely distended with gas; ingesta and digesta minimal | Turgid, slightly friable & engorged with blood | Edema of mediastinum & pericardial connective tissue | Left Kidney enlarged, friable, congested; hemorrhage found in pylorus, duodenum, and urinary bladder mucosa |
08213 | IT | Mottled, hemorrhagic & congested. Severity greatest in caudodorsal lobes. Tracheal mucosa is hemorrhagic, congested and edematous | Minimally congested & edematous | Diffusely distended with moderate amounts of gas; ingesta and digesta minimal | Turgid, slightly friable | Abundant gelatinous edema of mediastinum and pericardial connective tissue | Urinary bladder and uterus had multifocal mucosal hemorrhage |
08181 | IT | Slightly congested/hyperemic with a few areas of consolidation. Severity greatest in caudodorsal lobes which have multifocal hemorrhage. Tracheal mucosa is hemorrhagic, congested and edematous | Minimally congested & edematous | Mildly distended with gas; ingesta and digesta minimal | Turgid, slightly friable, congested | Abundant gelatinous edema of mediastinum and pericardial connective tissue | Adrenals slightly congested; pylorus & duodenum have scattered petechial hemorrhages on mucosa, with serosal hemorrhage and edema surrounding the duodenum and pancreas |
08210 | Aerosol | Mildly congested with small multifocal areas of hemorrhage in cranial and caudodorsal lobes. Tracheal mucosa is congested and edematous | Minimally congested & edematous | Ingesta and digesta minimal | Turgid, slightly friable | Edema of the mediastinum and pericardial connective tissue | Multifocal mucosal hemorrhage of urinary bladder mucosa |
08095 | Aerosol | Mildly congested with multifocal areas of hemorrhage, primarily in caudodorsal lobes. Tracheal mucosa is congested and edematous | Minimally congested & edematous | Ingesta and digesta minimal | No changes noted | Edema of the mediastinum and pericardial connective tissue | Multifocal mucosal hemorrhage of urinary bladder mucosa |
08206 | Aerosol | Mildly congested with small multifocal areas of hemorrhage primarily in the caudodorsal lobe | Minimally congested & edematous | Ingest and digesta minimal | Turgid, slightly friable | Edema of mediastinum and pericardial connective tissue | Multifocal mucosal hemorrhage of urinary bladder mucosa |
