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").
The number of somatic cells increases in response to pathogenic bacteria like Staphylococcus aureus, a cause of mastitis. The SCC is quantified as cells per milliliter. General agreement rests on a reference range of less than 100,000 cells/mL for uninfected cows and greater than 250,000 for cows infected with significant pathogen levels.
