photorepair of pyrimidine dimers in the epidermis of the marsupial monodelphis domestica.		1984	6483989
differential nor activities in somatic and germ cells of monodelphis domestica (marsupialia, mammalia).	somatic and germ cells of the gray short-tailed opossum (monodelphis domestica) were analyzed cytogenetically by c-banding, g-banding, and silver staining. the diploid chromosome number was found to be 18. c-banding revealed constitutive heterochromatin at the centromeres of all chromosomes, with additional heterochromatin on one arm of the y. silver staining for the localization of nucleolus organizer regions (nors) showed nors on the x and on a pair of autosomes, tentatively designated as chro ...	1983	6617263
water balance in monodelphis domestica (didelphidae) from the semiarid caatinga of brazil.	1. water conservation and energy metabolism in a semiarid-area, neotropical marsupial (monodelphis domestica) were studied in the laboratory. 2. the rate of energy consumption in this species is low, corresponding with results reported for australian and other neotropical marsupials. 3. evaporative water loss rate is low and comparable to that of several desert small rodents, when body size differences are taken into account; however, the ratio of metabolic water production-to-evaporative water ...	1983	6132710
effect of inbreeding on juvenile mortality in some small mammal species.	in breeding records for 12 species of small mammals from 9 families in 3 orders, individuals with an inbreeding coefficient of 0 were classified as non-inbred, those with inbreeding coefficients greater than 0 as inbred. juvenile mortality was defined as all deaths prior to 1/2 of the age of sexual maturity for each species. it was significantly higher for inbred than for noninbred animals in 11 of the 12 species using a 1-tailed sign test, and by fisher's exact test in 3 species. monodelphis do ...	1982	7043080
care and breeding of the gray, short-tailed opossum (monodelphis domestica)	husbandry procedures were developed for the gray short-tailed opossum (monodelphis domestica) based on experience with several colonies that were self-sustaining for up to 4 years (five generations). individual adult animals (80-155 g) were maintained in modified single rat or guinea pig cages, although larger cages with floor areas of at least 2,000 cm2 were required for breeding. diets consisted primarily of ground meat, dried milk powder, wheat germ, and vitamin supplements. switching males i ...	1982	7144118
genetic diversity of laboratory gray short-tailed opossums (monodelphis domestica): effect of newly introduced wild-caught animals.	the colony of gray, short-tailed opossums (monodelphis domestica) at the southwest foundation for biomedical research, the primary supplier of this species for research purposes, was founded with nine animals trapped in 1978 in the state of pernambuco, brazil. since 1984, 14 newly acquired founders from the state of paraiba, brazil have contributed to the gene pool of the colony. the animals from paraiba and their descendants are significantly larger than the founders from pernambuco and their d ...	1981	1320155
feeding preferences of lutzomyia longipalpis (diptera: psychodidae), the sand fly vector, for leishmania infantum (kinetoplastida: trypanosomatidae).	leishmania infantum, the causative agent of visceral leishmaniasis (vl) in brazil, is spread mostly by the bite of the sand fly lutzomyia longipalpis (lutz & neiva). we trapped sand flies in endemic neighborhoods near natal, brazil, where cases of human and dog vl were documented. amplification of species-specific cytochrome b (cyt b) genes by polymerase chain reaction revealed that sand flies from rural and periurban areas harbored blood from different sources. the most common source ofbloodmea ...	0	24605474
the genomes of the south american opossum (monodelphis domestica) and platypus (ornithorhynchus anatinus) encode a more complete purine catabolic pathway than placental mammals.	the end product of purine catabolism varies amongst vertebrates and is a consequence of independent gene inactivation events that have truncated the purine catabolic pathway. mammals have traditionally been grouped into two classes based on their end product of purine catabolism: most mammals, whose end product is allantoin due to an ancient loss of allantoinase (alln), and the hominoids, whose end product is uric acid due to recent inactivations of urate oxidase (uox). however little is known a ...	0	20161190
the opossum genome: insights and opportunities from an alternative mammal.	the strategic importance of the genome sequence of the gray, short-tailed opossum, monodelphis domestica, accrues from both the unique phylogenetic position of metatherian (marsupial) mammals and the fundamental biologic characteristics of metatherians that distinguish them from other mammalian species. metatherian and eutherian (placental) mammals are more closely related to one another than to other vertebrate groups, and owing to this close relationship they share fundamentally similar geneti ...	0	18676819
