Abstract

We describe a second case of human infection caused by Thelazia gulosa (the cattle eye worm), likely acquired in California. For epidemiologic purposes, it is important to identify all Thelazia recovered from humans in North America to the species level.

Keywords: Thelazia; conjunctivitis; helminth; parasitic; thelaziasis.
