This 14 day old calf had diarrhea. It was previously given electrolytes by esophageal tube, and the operator noted he had trouble positioning it correctly. This may have cause the peri-laryngeal lesion. There were also calf-diphtheria like lesions in the tongue, abomasum and forestomachs. The calf had a cardiac infarct, as well as leptomeningitis. The calf was positive for F. necrophorum by IHC (but not microbiologically; a fastidious organism), as well as for coronavirus, H. somni and parainfluenza 3.

Ulcerative glossitis, chronic, focall, with intralesional F. necrophorum
This 14 day old calf had had diarrhea. It was previously given electrolytes by esophageal tube. The operator noted he had trouble positioning it correctly. There was also necrotizing laryngitis, abomasitis, and similar necrotizing lesions in all forestomachs. The luckless bull calf also had a large cardiac infarct, as well as leptomeningitis. He was positive for F. necrophorum by IHC (but not microbiologically; a fastidious organism), as well as for coronavirus, H. somni and parainfluenza 3.
This 14 day old calf had diarrhea. It was previously given electrolytes by esophageal tube, and the operator noted he had trouble positioning it correctly. This may have caused an extensive necrotizing peri-laryngeal lesion. There were calf diphtheria-like lesions in tongue, abomasum and forestomachs. The calf had leptomeningitis. He was positive for F. necrophorum in tongue, larynx, pharynx and forestomach by IHC (but not microbiologically; a fastidious organism), as well as for coronavirus, H. somni and parainfluenza 3 on other tissues.

Diarrhea associated with Streptococcus equi spp. zooepidemicus and Actinobacillus sp. septicemia
This 3 week old colt had diarrhea and was intensively treated with antibiotics and I/V fluid. The main lesions at necropsy were oral ulcers from which S. equi spp. zooepidemicus was isolated, and dehydration. Streptococcus equi spp. zooepidemicus and Actinobacillus sp. were cultured from multiple tissues.
These wild turkeys (Meleagris gallopavo) were susceptible to a 2022 strain of H5N1 influenza virus. Principal gross lesions were hemorrhage and necrosis in ovaries, splenomegaly, and heavy red lungs. Histologically the main lesions were necrosis, hemorrhage and inflammation in lung, spleen, ovaries and gastrointestinal tract.
