Occurrence of Cryptosporidium spp. oocysts in the maintenance water of Antillean manatees (Trichechus manatus) in captivity. The goal of this research was to verify the occurrence of Cryptosporidium spp. oocysts in the water consumption and supply of pools used by Antillean manatee (Trichechus manatus) in captivity. Six samples were collected from the pool's supply system (at the beach), water used for manatee consumption, mineral water used in the preparation of artificial milk formulas offered to orphan manatee calves, also used in permanent maintenance pools in the visitation area, and water utilized in the rehabilitation area, where calves of all ages were kept. Before the water samples were processed, each sample was submitted to a filtration process. The diagnosis of the parasite was obtained by Kinyoun technique and the positive samples were submitted to the Direct Immunoflorescence Test. The results showed the presence of Cryptosporidium spp. oocysts in 66.67% (4/6) of the samples from the water supply system and pool, with eight to 56 oocysts per liter. There was evidence that the water used in the maintenance of the Antillean manatees could be an important medium for hydric transmission of Cryptosporidium spp. and that it may be a predisposing factor to the occurrence of cryptosporidiosis in Antillean manatees in captivity.
