In the present experiment, trypomastigotes of different virulence were comparatively studied in terms of their infectivity to mouse macrophages, newly cultured fibroblasts from mouse heart and established fibroblasts (L-cells). Virulent trypomastigotes showed more rapid development both in macrophages and newly cultured fibroblasts than those of low virulence. On the other hand, trypomastigotes of low virulence grew more rapidly in established fibroblasts than highly virulent ones, though both of them showed slower development in established fibroblasts than in newly cultured fibroblasts. Trypomastigotes of low virulence could not induce apparent infection in normal mice but could induce gradually progressive infection in nude mice. These results show that virulence of T. cruzi in mice relates to the speed of parasite growth not only in macrophages but also in newly cultured fibroblasts and enable us to make the following suggestion that the age of cultured cells to be infected must be taken into consideration when examining the virulence of T, cruzi in cell culture systems.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"熱帯医学 Tropical medicine 27(4). p211-219, 1985","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"106124","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hermosura, Ma.
