Abstract: | Studies of the influence of genotypic alterations on the murine virulence of Aspergillus nidulans Eidam are reviewed to emphasize the potential of this fungus for genetic studies of virulence.The filamentous ascomycete Aspergillus nidulans Eidam produces a fatal systemic mycosis characterized by signs referable to the central nervous system after its intravenous inoculation into male DBA/2J mice. The time and dosage of conidia required to produce a fatal infection are functions of the specific virulence of the strain. In previous investigations we showed that the murine virulence of A. nidulans was strongly dependent on genotype (21–24). In this paper the effects of a number of different genotypic alterations on the virulence of A. nidulans will be reviewed to emphasize the potential of A. nidulans as a model for genetic studies of fungal virulence. The paucity of genetic information regarding the virulence of mycotic zoopathogens makes such studies highly desirable. |
