Algal infections are rare in humans and domestic animals. Prototheca spp. and Chlorella spp. are among the most commonly reported. Herein, we present a brief review on Chlorella spp. infections and related pathologies and discuss this information including a natural case in a sheep in Mexico with a disseminated form of the disease.

Nematodes similar to Oxyspirura sp. were recovered from the cornea and nictitating membrane of a fulvous owl (Strix fulvescens). The bird had been captive for several months, but died suddenly. It had no clinical history of prior diseases, including ocular lesions.
