Evolutionary events shaping the genome of Cryptococcus neoformans and their effects on pathogenesis

点击翻译按钮获取中文摘要

Recurring infection in patients with fungal meningitis caused by Cryptococcus neoformans is typically caused by persistence of the original infection rather than reinfection with a new strain. Our analysis of relapse strains shows that small-scale alterations frequently occur at the chromosome ends - regions containing important pathogenesis-related genes in other pathogens. We seek to characterise this microevolution further to understand how it contributes to the success of this pathogen.
