Occurrence of Cryptosporidium spp. infection in Antillean manatee (Trichechus manatus).
Revista Brasileira de Parasitologia Veterinária 18(1): 60-61. Jan.-Mar. 2009.
–ABSTRACT: Cryptosporidiosis is a zoonosis which can affect man and a wide range of domestic and wild animals, mainly immunodeficient individuals. The objective of this paper was reported the occurrence of a Cryptosporidium infection in Antillean manatee. After an unusual behavior of an Antillean manatee kept in captivity at the Centro Mamíferos Aquáticos, ICMBio--FMA, clinical examination and posterior fecal sampling was performed. Fecal samples were examined by the Kinyoun technique, Direct Immunofluorescence Test and also examined by 4',6'-Diamidino-2-Phenylindole (DAPI) staining. At the clinical examination, the animal showed signs of abdominal pain. The results obtained by light and fluorescence microscopy analysis showed the presence of Cryptosporidium spp. oocyst in feces of this manatee.

Occurrence of Cryptosporidium spp. in Antillean manatees (Trichechus manatus) and Amazonian manatees (Trichechus inunguis) from Brazil.

–ABSTRACT: Infections by Cryptosporidium spp. in aquatic mammals is a major concern due to the possibility of the waterborne transmission of oocysts. The aim of the present study was to report the occurrence of Cryptosporidium spp. in Antillean manatees (Trichechus manatus) and Amazonian manatees (Trichechus inunguis) from Brazil. Fecal samples were collected and processed using Kinyoun's method. Positive samples were also submitted to the direct immunofluorescence test. The results revealed the presence of Cryptosporidium spp. oocysts in 12.5%% (17/136) of the material obtained from the Antillean manatees and in 4.3%% (05/115) of the samples from the Amazonian manatees. Cryptosporidium spp. infection was more prevalent in captive animals than in free-ranging specimens.

Eighteen years of Antillean manatee Trichechus manatus manatus releases in Brazil: lessons learnt.
Oryx 49(2): 338-344. 1 tab. 2 figs. 1 pl. DOI: 10.1017/S0030605313000896. April 2015.
–ABSTRACT: The Antillean manatee Trichechus manatus manatus was once widespread from the south-eastern coast of Brazil to Central America and the Caribbean. In Brazil habitat destruction and overhunting severely reduced and fragmented the wild population, restricting extant subpopulations to the north and north-east coast. In response to these threats an ambitious government-led programme was initiated in 1994, with the aim of rehabilitating orphaned manatee calves and releasing them into the southernmost subpopulation. The programme is unique within Brazil, and has invested unprecedented resources in post-release monitoring. So far 30 manatees have been released at three sites, with a high rate of success (> 75%). Time in captivity appears to be a key variable determining post-release success: too long or too short a time in captivity decreasing the probability of survival. We describe the main features of this long-term programme and identify six key lessons learnt: (1) close monitoring, health assessments and rescues can significantly increase the success of releases, (2) combining different monitoring techniques results in high-quality data and reduces tracking costs, (3) long-term studies are needed to effectively evaluate the results, (4) releasing manatees at c. 5 years of age can increase chances of success, (5) soft-release is important to aid acclimatization, and (6) the programme has been effective in raising awareness among the general public, supporting education and fund-raising.
