Abstract

This paper presents the necropsy findings in South American fur seal (Arctocephalus australis) pups from Uruguayan colonies. Animals ( ) were aged between 0 and 18 months old. From 0 to 6 months, 69.4% of the pups showed a poor body condition, while 68.8% of animals from 7 to 18 months had fair-to-good body condition. From 6 to 7 months of age, the stomach content included fishes, crustaceans, and foreign bodies. Starvation in the first months of life and traumatic lesions in pups older than 9 months were the most frequent causes of death. Uncinaria spp. was the only parasite found in the small intestine between 0 and 6 month-old pups. Parasites with indirect cycle (Contracaecum spp., Corynosoma sp., Tetrabothriidae) were present from 6 months of age as well as the first report of the nematode Strongyloides spp. in pinnipeds. Orthohalarachne spp. was found in the respiratory tract. Mycobacterium pinnipedii was isolated from 9 animals without gross pathological lesions. Other pathological conditions were found in lesser extent. This information contributes to the main causes of death of A. australis pups at different ages and could be useful to perform further health studies on this wild pinniped species.
