Survival of Corynebacterium renale, Corynebacterium pilosum and Corynebacterium cystitidis in soil.

Survival of the causative agents of bovine pyelonephritis, Corynebacterium renale, C. pilosum and C. cystitidis, was examined at 30 degrees C in autoclaved soil. In the soil from a paddock, C. renale and C. cystitidis survived for 56 and 63 days, respectively, and C. pilosum for a longer period of at least 210 days. In soil from a pasture, sand from an athletic field and sea sand, the survival of these bacteria was of shorter duration.
