REPRODUCTIVE CYCLE STAGE ASSESSMENT IN THE TWO-TOED SLOTH (CHOLOEPUS HOFFMANNI), PRELIMINARY RESULTS
Journal of Zoo and Wildlife MedicineThe number of two-toed sloths (Choloepus hoffmanni) has significantly decreased in the last years. Deepening the knowledge of this tropical mammal's reproductive physiology is essential to improve captive breeding within conservation programs for this species.

Leishmania Braziliensis in the Panamanian Two-Toed Sloth, Choloepus Hoffmanni
American Journal of Tropical Medicine and Hygiene, 1980A total of 498 two-toed sloths, Choloepus hoffmanni, collected in central Panama was examined for Leishmania braziliensis over a 10-year period. Isolations of the parasite from 96 (19.3%) of the animals were confirmed by culture and inoculation of golden hamsters. Improved culture techniques developed toward the end of the study assisted in determining

The spinal roots in the sloth (Choloepus hoffmanni peters)
Journal of Comparative Neurology, 1967AbstractIn the lower half of the thoracic region in Choloepus hoffmanni, a didactyl sloth, which possesses 23 dorsal vertebrae, the spinal roots assume a rostralward direction. This situation raises difficult problems in early embryological development as it already prevails — although slightly altered — in the 100 gm foetus. The myelinated nerve fiber

Choloepus hoffmanni (Hoffmann’s two-toed sloth)
1970These karyotypes were kindly donated by Drs. J. Corin and J. Corin-Frederic, University Liege, Belgium. The study was performed on ten animals (fibrous tissue culture) collected in Panama, Costa Rica and Equador. All possessed 49 chromosomes. Females are apparently XO, males have one unpaired element which in size is the 23rd autosome.

A 2-yr-old female captive-born Hoffmann's two-toed sloth (Choloepus hoffmanni) presented with respiratory disease. A severe inspiratory dyspnea with nasal congestion was observed with open-mouthed breathing and bilateral mucopurulent nasal exudate. Despite initial treatment with broad-spectrum antimicrobial therapy and anti-inflammatory and supportive ...

Trypanosoma (Herpetosoma) leeuwenhoeki, originally described in Panamanian sloths, was isolated from Didelphis marsupialis (Marsupialia) and Choloepus hoffmanni (Edentata) inhabiting the Pacific coast of Colombia. Trypanosomes were characterized by their large blood forms (total length 51-53 microns), poor infectivity for mice, and lack of development ...

Ventilatory responses to CO2, and hypoxia in the two-toed sloth Choloepus Hoffmanni
Respiration Physiology, 1974Abstract Sloths are unusual in that they have a low metabolic rate, a low body temperature and a low rate of secretion of thyroxine in comparison with most other mammals. Since it is known that any one of these features, if induced in a characteristic mammal, results in some altered state of the ventilatory control system, and its responses to ...

A Possible Vector of Endotrypanum schaudinni of the Sloth Choloepus hoffmanni, in Panama
Nature, 1964Endotrypanum schaudinni, a haemoflagellate of sloths, has a very wide geographical distribution in America, stretching from the Amazonian Basin in the South to Costa Rica in the North. It has been shown that the infection is limited to animals which live in forest regions1.

La fonction thyroidienne chez l'unau (Choloepus hoffmanni Peters)
General and Comparative Endocrinology, 1969Resume Le faible taux du metabolisme de repos et la basse temperature centrale du Paresseux Choloepus hoffmanni ont ete confirmes. Le poids relatif de la thyroide n'est pas anormal et l'insuffisance du tissu thyroidien ne peut etre invoquee pour expliquer un metabolisme de 34% inferieur a celui de Mammiferes de meme poids. Histologiquement, il s'agit
