Abstract Classified as a critical public health threat by the World Health Organization, Cryptococcus neo-formans infections with significant morbidity and mortality. Reports of cryptococcosis persistence, relapse, reinfection date back to 1950s, yet factors driving chronic remain poorly understood. A major challenge is scarcity serial patient specimens detailed medical records study simultaneous evolution pathogen host status. This provides first genomic phenotypic analysis in-host C. neoformans during lasting over year in six immunocompromised patients. We find fungal genome persistent infection characterized large-scale restructuring increasing heterogeneity. Phenotypic changes show diversification virulence traits antifungal susceptibility. Genotypically phenotypically distinct sub-lineages arise co-persist within same tissues, consistent model diversifying selection niche partitioning complex environment human hosts.
