Abstract
|
|
|
|
Acanthamoeba infection is associated with keratitis in humans; however, its associationwith keratitis in dogs remains unclear. To investigate this possibility, we collected 171conjunctival swab samples from dogs with eye-related diseases (65 with keratitis and106 without keratitis) at Chungbuk National University Veterinary Teaching Hospital, Korea, from August 2021 to September 2022. Polymerase chain reaction identified 9 samples (5.3%) as Acanthamoeba positive; of these, 3 were from dogs with keratitis (4.6%)and 6 were from dogs without keratitis (5.7%). Our results indicated no significant association between Acanthamoeba infection and keratitis, season, sex, or age. All Acanthamoeba organisms found in this study had the genotype T4, according to 18S ribosomal RNA analysis. Acanthamoeba infection in dogs might have only a limited association with keratitis.
