| chagas' disease in the amazon basin iv. host records of trypanosoma cruzi zymodemes in the states of amazonas and rondonia, brazil. | of 151 trypanosoma cruzi stocks from 117 different individual hosts collected in the states of amazonas and rondonia, 147 from 113 hosts were identified as zymodeme 1 (z1). these included t. cruzi stocks from three marsupial species, two rodent species and three triatomine species although most were from the common opossum, didelphis marsupialis. one t. cruzi stock from rhodnius robustus was identified as z1 with a z3 pgm character, one from sciurus sp. as z3 and two from monodelphis brevicaudat ... | 1984 | 6441530 |
| 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 |
| the opossum, didelphis marsupialis (marsupialia: didelphidae), as a reservoir host of leishmania braziliensis guyanensis in the amazon basin of brazil. | a total of 52 opossums (six species) were examined for evidence of infection with leishmania in three different areas of forest near manaus, amazonas state, brazil. no infections were detected in 27 opossums from a region of relatively undisturbed forest, including specimens of didelphis marsupialis (18); metachirus nudicaudatus (four); monodelphis brevicaudata (one); marmosa cinerea (two); m. murina (one) and m. parvidens (one). of 15 d. marsupialis captured from a biological reserve, much dist ... | 1981 | 7324129 |
| didelphidae marsupials (mammalia, didelphimorphia) from the late pleistocene deposit of the gruta dos moura cave, northern brazil. | the present study acknowledges the diversity of fossil marsupials from the gruta dos moura cave, as well as environmental and climatic aspects during the quaternary. the results show that this is the largest diversity of pleistocene marsupials recorded in a single cave: didelphis albiventris, d. aurita, gracilinanus agilis, g. microtarsus, marmosa murina, monodelphis brevicaudata, m. domestica and sairadelphys tocantinensis. furthermore, the described specimens are also part of the only fossil a ... | 2015 | 25806985 |
| functional-adaptive anatomy of the forelimb in the didelphidae, and the paleobiology of the paleocene marsupials mayulestes ferox and pucadelphys andinus. | an attempt to determine the locomotor activities of mayulestes ferox (borhyaenoidea) and pucadelphys andinus (didelphoidea) from the early paleocene site of tiupampa (bolivia) is presented. the functional anatomy of the forelimbs of these south american marsupials is compared to that of some living didelphids: caluromys philander, micoureus demerarae, marmosa murina, didelphis marsupialis, monodelphis brevicaudata and metachirus nudicaudatus. deductions from bone morphology to myology and locomo ... | 2001 | 11124686 |
| rate of evolutionary change in cranial morphology of the marsupial genus monodelphis is constrained by the availability of additive genetic variation. | we tested the hypothesis that the rate of marsupial cranial evolution is dependent on the distribution of genetic variation in multivariate space. to do so, we carried out a genetic analysis of cranial morphological variation in laboratory strains of monodelphis domestica and used estimates of genetic covariation to analyse the morphological diversification of the monodelphis brevicaudata species group. we found that within-species genetic variation is concentrated in only a few axes of the morp ... | 2015 | 25818173 |
| laelapine mites (acari: laelapidae) associated with small mammals from amazonas, brazil, including a new species from marsupials. | an intensive survey of ectoparasitic arthropods associated with small mammals in upland forests near manaus, brazil, provides information on the taxonomy and host distribution of laelapine mites in the amazonian region. we identified 5 genera and 21 species of these mites by comparison with representative museum specimens, the taxonomic literature, and, when possible, the original type specimens. these mites are host specific, with associations ranging from strict monoxeny (18 species) to oligox ... | 2005 | 15856870 |
