Plain-English summary

A 2-year-old mixed-breed dog from Nova Scotia was brought to the vet for symptoms like eye inflammation, excessive thirst and urination, and trouble walking. The vet diagnosed the dog with toxoplasmosis, a type of infection, but sadly, the dog passed away. An examination after death revealed that the dog also had protothecosis, another infection that can affect dogs. This case highlights the importance of considering multiple infections when diagnosing sick dogs, as they can complicate symptoms and delay treatment.

Abstract

A 2-year-old, neutered male mixed-breed dog from Nova Scotia, Canada was evaluated for panuveitis, polyuria, polydipsia, and hind limb ataxia. Toxoplasmosis was diagnosed ante-mortem based on markedly increasedtiters. The post-mortem examination confirmed systemic toxoplasmosis and demonstrated disseminated protothecosis. This article documents the first reported case of canine protothecosis in Atlantic Canada. Key clinical message: This case report demonstrates that protothecosis should be a clinical consideration for dogs in Canada. Co-infection with other organisms may occur, which may mask clinical signs and potentially delay diagnosis.
