[Clinical aspects and pathomorphology of Corynebacterium infection in cattle]

Clinical, paraclinical, and morphological investigations were carried out with a total of 12 cattle (9 calves and 3 cows) with an induced suppurative surgical infection caused by two strains of Corynebacterium pyogenes. It was established that such an experimental infection in cattle clinically ran a chronic course, involving predominantly the urinary and the digestive system as well as the joints. Morphologically, the infection was manifested as a chronic septicopyemia, with purulent nephritis and pyelonephritis, cystitis, splenitis, hepatitis, valvular meningoencephalitis, and absceses in various tissues and organs.
