Protothecosis is an important infection caused by Prototheca spp., an alga that affect humans and animals. Prototheca spp. infections determine losses of production and quality of life for the affected animals. In this disease, prevention and early diagnosis are essential to avoid the spread of the agent to susceptible hosts. This review aimed to assemble the reported cases of protothecosis in Veterinary Medicine, highlighting Prototheca species involved in the infections, the main animal species affected, as well as the clinical manifestations, diagnosis, and treatment. Our findings showed that protothecosis has been reported in various domestic and wild animal species, presenting diverse clinical manifestations, including mastitis in cows, respiratory manifestations in goats and cats, and a wide range of clinical signs in dogs. The clinical diagnosis and treatment of Prototheca spp. infections are difficult and infected animals are frequently discarded or euthanized. Due to the importance of this infection, protothecosis must be considered an important differential diagnosis in routine clinical Veterinary Medicine.
