Ocular infection of donkeys (Equus asinus) with Setaria equina.

Seven donkeys raised in different locations in Egypt were found to have a unilateral eye showing motile white worms in the aqueous humor. The parasites were surgically removed from the anterior chamber of the eye in five out of the seven donkeys, and were cleared, mounted and identified as Setaria equina based on light microscopic features. The ocular infection with S. equina reported herein may be the first reported aberrant cases in the Egyptian animals.
