Abstract: | A 20-yr retrospective study of disease prevalence was carried out for 51 sloths (34 Bradypus sp. and 17 Choloepus sp.) at the S?o Paulo Zoo. A total of 81 clinical disorders were detected, including nutritional (45.7%), digestive (12.3%), and respiratory (12.3%) problems and injuries (6.1%). A definitive diagnosis was not possible in 8.6% of the cases. The incidence of disease varied according to seasonal climate (winter, 32.5%; spring, 24%; summer, 22.9%; autumn, 20.5%), time in captivity (96.4% of diseases occurred within the first 6 mo and 3.6% occurred thereafter), and type of enclosure (quarantine cage, 96.4%; exhibition enclosure, 3.6%). Both young animals (86.7%) and adults (3.2%) were affected. Parasites were identified by fecal examination in 45.4% of animals with clinical illness (Ascaris sp., 80%; Coccidia sp., 20%). Bacteria such as Salmonella enteritidis, Escherichia coli, and Citrobacter freundii were isolated from feces and/or organs. The first 6 mo in captivity are critical for these animals. Proper management and early identification of medical conditions in captivity have implications for sloth population in the wild. |
