Main pathologic findings of 2 bycaught Franciscana dolphins (Pontoporia blainvillei) positive for nonhemotropic mycoplasma in a study of molecular detection and characterization of Mycoplasma spp. in marine mammals, Brazil

Case no. Gross findings Microscopic findings
ID85 External examination: multifocal linear imprints and incisions associated with net entanglement. Multifocal moderate teeth marks in all ventral aspects, particularly in the pedunculus. Spleen: moderate white pulp hyperplasia. Moderate diffuse congestion. Mild to moderate acute granulocytic splenitis. Mild to moderate expansion of the periarteriolar lymphoid sheaths with deposition of eosinophilic amorphous material and lymphocytolysis.
Lungs: marked diffuse congestion and mild edema. Multifocal mild atelectasis areas Lungs: moderate multifocal congestion and hemorrhage. Mild to moderate granulocytic pneumonia with interalveolar macrophages and pneumocytes. Mild multifocal atelectasis.
Axillary and mesenteric lymph nodes: moderate lymphadenomegaly Prescapular lymph node: mild to moderate acute granulocytic lymphadenitis with lymphocytolysis in germinal centers.
Central nervous system: mild to moderate cerebral congestion. Liver: mild ductal hyperplasia. Mild congestion.
Thyroid, thymus, kidney, and pituitary and adrenal glands: Mild to moderate congestion.
Tongue, cerebellum, brain, mesenteric lymph node, stomach, and intestines: no significant findings observed
ID173, calf of ID85 External examination: mild multifocal linear marks associated with net entanglement. Central nervous system: Mild to moderate congestion. Mild satellitosis and gliosis. Mild neuronophagia.
Lungs: marked congestion, mild to moderate pulmonary edema. Lung: Marked diffuse congestion and hemorrhage associated with moderate to marked multifocal edema. Mild to moderate granulocytic pneumonia with exfoliation of macrophages and pneumocytes in alveoli. Rare megakaryocytes.
Liver: Mild multifocal to coalescent pale areas. Moderate congestion. Liver: mild microgoticular degeneration and congestion.
Generalized congestion. Kidney: mild congestion and hemorrhage.
Spleen, skeletal muscle, adrenal glands, trachea, skin, stomach, mesenteric and rectal lymph nodes: no significant findings observed
