Large lamellar bodies and their role in the growing oocytes of the armadillo Chaetophractus villosus

Journal of Morphology, 2021
Abstract Oogenesis in the armadillo Chaetophractus villosus , a representative species of a mammalian basal clade, was investigated by light microscopy, transmission electron microscopy, and immunohistochemical localization of keratin.

Body temperature of the armadilloChaetophractus villosus(mammalia, dasypodidae)

Archives Internationales de Physiologie, de Biochimie et de Biophysique, 1994
Body temperature of the armadillo Chaetophractus villosus (n = 17) was studied during a period of 15 days. Deep rectal temperature (TB) was recorded at 9 am, 1 pm and 5 pm. Temperature in the laboratory was kept between 24.6 degrees C and 26.0 degrees C.

Haemostatic mechanisms of the armadillo Chaetophractus villosus (Xenarthra, Dasypodidae)

Comparative Clinical Pathology, 2005
Haemostatic mechanisms in humans are formed by two activation pathways, named tissular factor pathway and contact system pathway, and a common pathway, that promotes the formation of the fibrin clot. These mechanisms have also been identified in other mammals. In this work we evaluate their presence in the armadillo Chaetophractus villosus, a mammal of

Brucella suis in armadillos (Chaetophractus villosus) from La Pampa, Argentina

Veterinary Microbiology, 2014
Brucellosis is a zoonotic disease transmitted from an animal reservoir to humans. Both, wildlife and domestic animals, contribute to the spreading of these zoonosis. The surveillance of the animal health status is strictly regulated for domestic animals, whereas disease monitoring in wildlife does not exist.

Fibrinolytic system of the armadillo Chaetophractus villosus (Xenarthra, Dasypodidae)

Comparative Clinical Pathology, 2008
The fibrinolytic mechanism in the armadillo Chaetophractus villosus (Mammalia, Xenarthra, Dasypodidae) quite unknown until now was studied. Results were compared with those corresponding to healthy adult human beings. Whole blood lysis time and diluted blood lysis time were not detectable in armadillos.

Chaetophractus villosus (Hairy armadillo, peludo)

1974
Two male and 5 female specimens have been studied with identical results. Two females were collected in Uruguay and Argentina. The others came through the courtesy of Mr. Dennis A. Meritt, Lincoln Park Zoo, Chicago, Illinois, USA. The X chromosome was identified by autoradiography, and the Y is unmistakable.

Spermatogenesis is seasonal in the large hairy armadillo, Chaetophractus villosus (Dasypodidae, Xenarthra, Mammalia)

Reproduction, Fertility and Development, 2012
Very little is known about the distinct reproductive biology of armadillos. Very few studies have investigated armadillo spermatogenesis, with data available only for Euphractus sexcinctus and Dasypus novemcinctus. In the present study, we analysed male germ cell differentiation in the large hairy armadillo Chaetophractus villosus throughout the year ...

Seasonal changes in ovarian steroid hormone concentrations in the large hairy armadillo (Chaetophractus villosus) and the crying armadillo (Chaetophractus vellerosus)

Theriogenology, 2011
Knowledge of armadillo reproductive physiology is essential for developing ex situ and in situ assisted reproductive techniques for propagating and/or controlling populations of these animals. The present study included assessment of fecal sex steroids by radioimmunoassay, determining reproductive status via monitoring ovarian activity (in the wild ...
