quantitative analysis of forebrain pallial morphology in monotremes and comparison with that in therians.	we have made quantitative volumetric analyses of cerebral cortical (pallial) structures in the brains of three species of monotreme (ornithorhynchus anatinus, tachyglossus aculeatus, zaglossus bruijni) and compared the findings with similar measurements in a range of therian mammals (6 marsupials and 50 placentals). we have found that although the iso- and periallocortical grey matter volume of the monotremes is about what would be expected for their brain size, the proportion of iso- and perial ...	2019	31146906
forelimb myology of armadillos (xenarthra: cingulata, chlamyphoridae): anatomical correlates with fossorial ability.	descriptions of myology reflect adaptations of the post-cranium and are essential for understanding the functional morphology of animal limbs. armadillos (cingulata) are the most species-rich group of the basal superorder xenarthra, which is evident by their various lifestyles (subterranean vs. terrestrial) and levels of fossoriality (fossorial vs. semi-fossorial). while there have been several studies on limb bone proportions in numerous armadillos, limb myology has been reported for a limited ...	2020	33111984
morphological features of lower respiratory tract of nine-banded armadillo (dasypus novemcinctus, linnaeus, 1758).	the nine-banded armadillo (dasypus novemcinctus) is a mammal of the xenarthra superorder, which inhabits central, south and north america. few morphological descriptions are observed in this species, including the respiratory tract; therefore, the objective of this study was to describe morphologically the lower respiratory tract of the nine-banded armadillo. five animals were dissected, and the macroscopic and microscopic aspects were analysed. in the anatomical analysis, the perfusion techniqu ...	2020	32997356
hansen disease (leprosy) and armadillo exposure in arkansas: a case series.	although most cases of hansen disease (hd) in the united states are imported from endemic areas, a subset of cases are relate to exposure to nine-banded armadillos. several recent cases of hd in arkansas occurred in patients who had not traveled to endemic areas and who reported variable degrees of armadillo exposure.	2020	32379089
reservoirs and transmission routes of leprosy; a systematic review.	leprosy is a chronic infectious disease caused by mycobacterium leprae (m. leprae) and the more recently discovered mycobacterium lepromatosis (m. lepromatosis). the two leprosy bacilli cause similar pathologic conditions. they primarily target the skin and the peripheral nervous system. currently it is considered a neglected tropical disease, being endemic in specific locations within countries of the americas, asia, and africa, while in europe it is only rarely reported. the reason for a spati ...	2020	32339201
serological and molecular detection of infection with mycobacterium leprae in brazilian six banded armadillos (euphractus sexcinctus).	leprosy was recognized as a zoonotic disease, associated with nine-banded armadillos (dasypus novemcinctus) in the southern united states of america in 2011. in addition, there is growing evidence to support a role for armadillos in zoonotic leprosy in south america. the current study evaluated twenty specimens of the six-banded armadillo (euphractus sexcinctus), collected from rural locations in the state of rio grande do norte (rn), brazil for evidence of infection with mycobacterium leprae. s ...	2020	31775113
survey of leptospira spp. and brucella abortus in free-ranging armadillos from pantanal, brazil.	out of the 20 recognized species of armadillos in the world, 11 are found in brazil, and five of them are found in pantanal, one of the world's largest wetlands. beef cattle (bos taurus) farming is the main economic activity in this region, which promotes intense wildlife-livestock contact and increases the likelihood of pathogen exposure, including to agents with zoonotic and economic relevance. previous studies demonstrated that several wildlife species in pantanal have been exposed to brucell ...	2020	31596674
prevalence of mycobacterium leprae in armadillos in brazil: a systematic review and meta-analysis.	understanding the prevalence of m. leprae infection in armadillos is important because of evidence from brazil and other countries of an association between contact with armadillos and the development of hansen's disease (leprosy). our aim was to characterize studies which have investigated natural m. leprae infection in wild armadillos in brazil, and to quantify and explore variability in the reported prevalence of infection. we conducted a systematic review (prospero crd42019155277) of publica ...	2020	32203502
brain anatomy of two-toed sloth (choloepus didactylus, linnaeus, 1758): a comparative gross anatomical study of extant xenarthrans.	the neural system plays an important role in understanding some features of animals. anatomical complexity correlates with the increase of functional capacity. xenarthrans include anteaters (vermilingua), armadillos (cingulata) and sloths (folivora). this group is the base of eutherian mammals, and understanding the anatomy of its neural system could provide data for functional and evolutionary interpretations. the gross anatomy of the xenarthran brain is recorded. four extant families of pilosa ...	2020	31588601
anatomical description of the aortic arch of a rare species "the giant armadillo" (priodontes maximus; kerr, 1792).	the giant armadillo (priodontes maximus) is found in diverse habitats from south america. a female adult giant armadillo with a body mass of 45 kg was used. the animal was a victim of trampling on highway ac-40, at 70 km, near the municipality of capixaba-acre and the corpse donated to the animal anatomy laboratory at federal university of acre (ufac). the arterial system was filled with natural latex via the thoracic aorta in a direction opposite the blood flow to facilitate the description of ...	2020	31063200
comparative metal analysis in a species assemblage of mammals from the southeastern united states.	metal pollution commonly occurs in many terrestrial environments and may pose a threat for the animals inhabiting such areas. here, we present concentrations of six metals (cadmium [cd], copper [cu], nickel [ni], lead [pb], selenium [se], and zinc [zn]) in the liver tissues of seven species of mammals obtained from a study that examined the impact of mesopredator removal on northern bobwhite (colinus virginianus) populations. a total of 1326 samples were collected from 2003 to 2006 at four sites ...	2020	32323028
