Corynebacterium bovis
Corynebacterium bovis is a pathogenic bacterium that causes mastitis and pyelonephritis in cattle.
C. bovis is a facultatively anaerobic, Gram-positive organism, characterized by nonencapsulated, nonsporulated, immobile, straight or curved rods with a length of 1 to 8 µm and width of 0.3 to 0.8 µm, which forms ramified aggregations in culture (looking like "Chinese characters").
