What is your diagnosis? (46)


  Histopathology showed that the lesions consisted of an embolic nephritis (caused by septic emboli originating in another focus of primary infection, typically in the endocardium of the cardiac valves) and severe infarction, caused by bigger emboli able to clog arteries. The microbiological culture gave a negative result, thus the etiologic agent could not be identified in this case, but in cattle Trueperella pyogenes is usually isolated from such lesions.
