Ocular alterations in dogs naturally infected by Leishmania (Leishmania) chagasi

Abstract

Ocular conditions, anti-Leishmania antibodies and total protein of the aqueous humor were studied in dogs naturally infected by Leishmania (Leishmania) chagasi. Fifty dogs were analyzed and assigned into two groups of 25 animals each. All animals were submitted to routine ophthalmic exam. Results showed that 76% of the affected animals presented ocular signs, being uveitis the predominant. The mean of total protein in the aqueous humor of animals with uveitis was higher (P<0.05) when compared to the mean of animals with other ocular signs or no clinical sign. The anti-Leishmania chagasi antibody values in plasma were superior to those found in the aqueous humor (P<0.05).
