Abstract: | Dogs affected with chronic superficial keratitis (CSK) and clinically normal dogs were tested for cellular hypersensitivity, using the leukocyte migration-inhibition (LMI) technique to 3 ocular antigens (Staphylococcus aureus and corneal and iridal proteins). Affected dogs had statistically significant increases in hypersensitivity cellular responses against corneal and iridal antigens. Affected dogs did not differ from clinically normal dogs in their cell response to S aureus. |
