| chagas's disease in the amazon basin: ii. the distribution of trypanosoma cruzi zymodemes 1 and 3 in pará state, north brazil. | in pará state, brazil, 123 trypanosoma cruzi stocks were isolated from 12 silvatic mammal species, five silvatic triatomine species and individuals with acute chagas's disease. 100 t. cruzi stocks were identified as zymodeme (z) 1, 17 as z3 and 6 as z3 with z1 asat character, but none were t. cruzi z2. z1 was predominantly isolated from arboreal mammals, especially didelphis marsupialis; z3 was mainly found in terrestrial or burrowing mammals, particularly dasypus novemcinctus and monodelphis br ... | 1981 | 7036428 |
| notes on parasitism by amblyomma humerale (acari: ixodidae) in the state of rondônia, western amazon, brazil. | the tick amblyomma humerale koch is endemic to south america. all host records refer to the adult stage parasitizing tortoises, mostly yellow-footed tortoise, geochelone denticulata (l.), and red-footed tortoise, geochelone carbonaria (spix). the current study reports the presence of a. humerale in the state of rondônia, brazil. a total of 215 adult ticks (201 males, 14 females) was collected from six g denticulata in an indian reserve and nine geochelone sp. in rural monte negro county, giving ... | 2002 | 12495177 |

| morphology of the tongue of vermilingua (xenarthra: pilosa) and evolutionary considerations. | the tongue of anteaters (xenarthra, pilosa, vermilingua) is a highly specialized for myrmecophagy. here, we describe the topography and histology of the tongue, and compare it to that of other xenarthrans and other myrmecophagous eutherian mammals. the tongue of vermilingua is long and slender, with an apical protuberance, which differs between myrmecophagidae and cyclopes didactylus. in the former, the rostral region is conical, and in the latter, it is dorsoventrally compressed, as observed in ... | 2017 | 28643449 |
| phylogeographic history of south american populations of the silky anteater cyclopes didactylus (pilosa: cyclopedidae). | cyclopes didactylus, commonly called silky anteater, is the smallest and least studied of the anteaters. it is an arboreal species occurring in rainforests, ranging from southern mexico to central and south america, with an apparently disjoint distribution between amazon and atlantic rainforests in brazil. although seven subspecies are recognized, little is known about its geographical variation. thus, to evaluate the population dynamics and evolutionary history of the south american silky antea ... | 2017 | 28199442 |
| mitotic and meiotic chromosome studies in silky anteater cyclopes didactylus (myrmecophagidae: xenarthra). | the karyotype of a male pigmy anteater, cyclopes didactylus, an endangered species from the amazon region, is described. the size and morphology of the x and y chromosomes in mitotic and meiotic analyses is recorded and discussed. | 2000 | 10756982 |
| comparative masticatory myology in anteaters and its implications for interpreting morphological convergence in myrmecophagous placentals. | ecological adaptations of mammals are reflected in the morphological diversity of their feeding apparatus, which includes differences in tooth crown morphologies, variation in snout size, or changes in muscles of the feeding apparatus. the adaptability of their feeding apparatus allowed them to optimize resource exploitation in a wide range of habitats. the combination of computer-assisted x-ray microtomography (µ-ct) with contrast-enhancing staining protocols has bolstered the reconstruction of ... | 2020 | 32983632 |
| morphological description of smell glands in cyclopes didactylus. | a macroscopic and microscopic study of the mandibular organ of the silky anteater (cyclopes didactylus) was carried out. the organ extends from below the zygomatic bone line to the middle of the mandible body, between the skin and the masseter muscle, on both sides of the animal. it has an average length of 11.7 mm and a width of 6.3 mm. in the mesoscopic analysis, it was observed that the organ presents in yellowish color due to the high amount of sebaceous content. in the histological analysis ... | 2019 | 31087731 |
