We surveyed 13 carcasses of marine mammals (12 Trichechus manatus and one Stenella clymene) that had stranded in northeastern Brazil during 1990–2013 for infectious diseases by screening tissues from the collection of the Brazilian National Center of Research and Conservation of Aquatic Mammal, Chico Mendes Institute for Biodiversity Conservation. Brucella spp. and Mycobacterium spp. were investigated by culturing and PCR of tissue samples, whereas Sarcocystidae parasites, Leptospira spp., and Morbillivirus were surveyed for using specific PCR assays. Brucella spp. and Mycobacterium spp. were not isolated through microbiologic culturing, and all animals were negative for detection of Sarcocystidae parasites, Leptospira spp., Mycobacterium spp., and Morbillivirus by PCR assays. All manatees were negative for Brucella spp. infection, but Brucella ceti was detected in the brain tissue of an S. clymene calf by using a PCR assay.
