Adhesion of Corynebacterium renale, Corynebacterium pilosum, and Corynebacterium cystitidis to bovine urinary bladder epithelial cells of various ages and levels of differentiation.

The adhesion of Corynebacterium renale, Corynebacterium pilosum, and Corynebacterium cystitidis to various epithelial cell layers of bovine urinary bladders was examined. Adhesion was most efficient to the urinary sediment epithelial cells and the superficial cells immediately before shedding, followed by the remaining superficial cells and intermediate cells in this order, and least efficient to the deeper intermediate and basal cells. Incubation of the intermediate cells for 6 h increased the number of bacteria that adhered to these cells.
