trypanosoma cruzi in the sylvatic environment: distinct transmission cycles involving two sympatric marsupials.	thirty-five specimens of philander frenata and 36 didelphis marsupialis were captured in the same atlantic forest area of brazil between 1992 and 1994. haemocultures showed that 50% of p. frenata and 60% of d. marsupialis were infected with trypansoma cruzi. biological, biochemical and molecular characterization of the isolates suggested 2 distinct transmission cycles of t. cruzi occurred between these 2 sympatric didelphids. the t. cruzi isolates could be distinguished according to their associ ...	2000	11132378
trypanosoma cruzi in marsupial didelphids (philander frenata and didelhis marsupialis): differences in the humoral immune response in natural and experimental infections.	philander frenata and didelphis marsupialis harbor parasitism by trypanosoma cruzi without developing any apparent disease and on the contrary to d. marsupialis, p. frenata maintains parasitism by t. cruzi ii subpopulations. here we compared the humoral immune response of the two didelphids naturally and experimentally infected with t. cruzi ii group, employing sds-page/western blot techniques and by an indirect immunofluorescence assay. we also studied the histopathological pattern of naturally ...	2003	12806461
