Corneal scrapings are examined with direct fluorescent tests to detect inclusion bodies for the diagnosis of infection caused by

Explanation:
Direct fluorescent antibody testing of corneal scrapings targets chlamydial antigens inside infected epithelial cells by labeling the intracellular inclusions. Chlamydia trachomatis forms these inclusions within conjunctival and corneal epithelial cells during infection, and they illuminate with fluorescent antibodies, making this method a classic way to diagnose ocular chlamydial infections such as trachoma and inclusion conjunctivitis. The other organisms listed are not diagnosed this way in corneal scrapings, as their infections are identified by different patterns, specimens, or methods.
